XenApp & XenDesktop / Virtual Apps and Desktops (excluding Machine Creation Services):
| wdt_ID | Brief Description of Issue | Brief Description of Fix | Applicable Product Versions Affected (if known) | Link to supplemental Support Article(s) |
|---|---|---|---|---|
| 1 | Windows Media Player throws an error "An error occured while playing the file" when attempting to play mp4 videos or "Windows Media Player encountered a problem while playing the file" when attempting to play wmv videos. | A new registry DWORD needs to be created within "HKLM\Software\Citrix\HDXMediaStream" for 32-bit machines and "HKLM\Software\Wow6432Node\Citrix\HdxMediaStream" for 64-bit machines. The DWORD name is "UseDefaultRenderers" with a value of "0x1". | Citrix XenDesktop 7.6 to 7.13. | https://support.citrix.com/article/CTX227223 |
| 2 | USB redirection is not working for signature pad. | Manufacturers of signature pads may provide additional client and/or server components that need to be loaded in order for signature pad operations to succeed in ICA sessions. For example ePAD provides drivers for the client and server and an ePadLink utility for testing functionality on both the client and VDA. These components may also enable the redirection of signature pads into the VDA session. | https://support.citrix.com/article/CTX212103 | |
| 3 | XenApp 7.6 VMs randomly become unresponsive. | A deadlock situation between 2 threads causes this issue. Upgrade the VDA to version 7.8 which contains fix "LC4195". | Citrix XenApp 7.6. | https://support.citrix.com/article/CTX208386 |
| 4 | Citrix Studio reports "The security timestamp is invalid" when browsing Machine Catalogs or Delivery Groups. | Resync the clock of each Delivery Controller in the farm using command "w32tm /resync". The default maximum acceptable different in time between a client computer clock and the Domain Controller clock is 5 minutes. | https://support.citrix.com/article/CTX223992 | |
| 5 | VDA failed to uninstall or upgrade because profilemgt_x64.msi failed to uninstall. The error reported is "Installation of MSI File 'profilemgt_x64.msi' failed with code 'InstallFailure' (1603)". | This is to be resolved by Citrix. In the meantime, you should as a workaround follow the three steps contained in the CTX article. | Citrix XenDesktop 7.6 or 7.6 LTSR. | https://support.citrix.com/article/CTX226859 |
| 6 | VDA blue screens randomly and all changes on standalone VDA are lost after reboot. | Upgrade to XenDesktop 7.14 or later. Otherwise, attach the VDA VHD to another computer, open the System hive, make registry changes noted in CTX article and then detach the VHD. | Citrix XenApp 7.11. | https://support.citrix.com/article/CTX222825 |
| 7 | You receive error "Could not connect to Orchestration Service" after upgrade to XenDesktop 7.15. | During the Site upgrade the "OrchDBConnection" and "TrustDBConnection" schema was not created. You must run the failed commands manually to create the Orchestration database connections. | Citrix XenDesktop 7.15. | https://support.citrix.com/article/CTX226882 |
| 8 | Schannel Event IDs 36888 and 36874 are reported on VDAs. | These errors appear due to the client and server being unable to communicate correctly, which may be caused by certificate or cipher suite issues. Citrix report that it is safe to ignore these errors. | https://support.citrix.com/article/CTX226770 | |
| 9 | A "1030" error occurs when connecting to a Remote PC connection. | Turn off the proxy in Internet Explorer or set "ProxyType" to "None" in default.ica. McAfee Web Gateway was configured as a proxy on the client. This was blocking the ICA connection request from reaching the VDA. This issue could be caused by other proxies too. | https://support.citrix.com/article/CTX226744 | |
| 10 | When connecting to a published desktop from Mozilla Firefox you receive "The connection to ... failed with status (Unknown client error 0)" or "Unable to launch your application. Contact your help desk with the following information: Cannot connect to the Citrix XenApp Server. The Citrix SSL server you have selected is not accepting connections". | Download Firefox 53.067 64-bit. It seems that the 32-bit version of Firefox 52.0.2 is not working and causing these errors. | Citrix XenDesktop 7.12 and Mozilla Firefox. | https://support.citrix.com/article/CTX222961 |
| 11 | A second logon prompt appears after users have logged on to StoreFront and launched a published resource. | This can be caused by a number of things. Configuration steps need to be checked and rectified if applicable as mentioned in the CTX article. | https://support.citrix.com/article/CTX220154 | |
| 12 | The Citrix Monitor Service may intermittently lose connectivity to the Monitoring SQL Database. The connection restores on its own after some time. In Event Viewer you see Event ID 1201 "The connection to the database has been lost" and Event ID 1200 "The connection to the database has been restored". | Collect WireShark logs from the Delivery Controller and SQL to make sure there is no intermittent network issues. Check for performance issues on SQL using PSSDIAG logs and evaluate increasing the Connection Pool size of the Citrix Monitor Service. | Citrix XenApp and XenDesktop 7.12 and 7.13. | https://support.citrix.com/article/CTX226658 |
| 13 | Users are unable to launch published applications intermittently with no error being displayed to the user. Citrix Studio also shows an active desktop session for the user even though the Delivery Group is set to provide applications only. | This was caused by multiple application launch requests within a few seconds. Uncheck "Auto Launch Desktop" and change the Multi-click duration from the default 3 seconds to 5 seconds. | Citrix XenDesktop 7.12 to 7.14. | https://support.citrix.com/article/CTX226606 |
| 14 | On GPU enabled VDAs a grey screen shows and Event ID "1005 is recorded in the Application Event Log indicating that "CtxUvi" has disabled itself. | The CtxUvi driver fails to load hooks correctly. Create a DWORD with name "UviEnabled" and value "0x1" under "HKLM\SYSTEM\CurrentControlSet\Services\CtxUvi" and then disable Group Policies that are set to modify the AppInit_Dlls registry value. | Citrix XenDesktop 7.12 to 7.14. | https://support.citrix.com/article/CTX226605 |
| 15 | When VDA 7.9 or newer is used, Microsoft Office activation fails. | The Software Protection Service fails to start. The service times out on system startup after about 30 seconds. Starting the service manually resolves the issue. Create a registry string with name "UviProcessExcludes" and vaue "sppsvc.exe" under "HKLM\SYSTEM\CurrentControlSet\Services\CtxUvi" on each VDA. | Citrix XenApp 7.9 to 7.14. | https://support.citrix.com/article/CTX223973 |
| 16 | A JavaScript form may jump to the top unexpectedly in Google Chrome when VDA is installed on Windows 7. | Disable the "Citrix Multi Touch" driver and service by editing the registry of the VDA. | Windows 7. | https://support.citrix.com/article/CTX227229 |
| 17 | Disabling Triple DES on the VDA breaks SSL connections to the VDA. | You must exclude Triple DES from the SSL Cipher Suite on each VDA to make sure an ICA connection does not attempt to use this cipher. | https://support.citrix.com/article/CTX226049 | |
| 18 | CTXAppVComAdmin account is missing. | As of XenApp and XenDesktop 7.14, this account is no longer created and is replaced by a "CtxAppVService" service which performs the same function. No further user interaction is required. | Citrix XenApp and XenDesktop 7.14. | |
| 19 | Application and desktop launches continue to fail for up to 6 minutes after a Controller fails, even though there are multiple Controllers. | As soon as a Controller fails, the VDA does not realise for up to 5 minutes until it sends a heartbeat ping, realises the Controller is unavailable and re-registers with another Controller. This explains the delay. You can decrease the heartbeat interval by changing the "HeartbeatPeriosMs" value on each Controller. | https://support.citrix.com/article/CTX223819 | |
| 20 | After a SQL failure, all VDAs apart from one successfully registered with the Delivery Controller. | The one affected VDA could not start the "Citrix Desktop Service". The VDA was missing a "brokeragent.exe.config_orig" file. In order to resolve, reinstall the VDA. | https://support.citrix.com/article/CTX218001 | |
| 21 | VDA 7.7 install fails with error "XDMI:CAC3C7EE Exception: Citrix.MetaInstaller.MetaInstallerException" and "failed with error code -4". | Post install the user account you are using should have access to the RDP listener. If it doesn't the install will fail. Add the user you are using to install the VDA to the "Remote Desktop Users" group and try again. | https://support.citrix.com/article/CTX206629 | |
| 22 | App-V breaks after upgrading VDA from 7.6 to 7.11. When launching an App-V application you receive error "Application failed to start. The Citrix Server is unable to process your request to start this published application". | CtxAppLauncher.exe was missing after the VDA installatin. Run a repair of the VDA and then confirm this file exists under "C:\Program Files\Citrix\Virtual Desktop Agent\". | https://support.citrix.com/article/CTX218328 | |
| 23 | Session timeouts configured via Active Directory within the "Sessions" tab of a users properties no longer works on Windows Server 2012 R2. It did previously work on Windows Server 2008 R2. It also works via RDP sessions. | This seems to be a design or product limitation in Windows Server 2012 R2. As a workaround you should use Group Policy to configure timeout settings. | https://support.citrix.com/article/CTX218916 | |
| 24 | When users launch a published instance of Outlook 2013 from Windows 10 client machines, the application crashes. Other applications such as Excel and Word work fine. | This seems to be caused by a .NET exception as it looks for DLL "penimc.dll". Upgrade .NET to a newer version. | Citrix XenApp 7.7. | https://support.citrix.com/article/CTX226354 |
| 25 | You receive database connection failures on an AlwaysOn SQL cluster using "MultiSubnetFailover". | The SQL Cluster Listener IP was not getting updated in DNS which was the cause of these database dicsonnections. | https://support.citrix.com/article/CTX214738 | |
| 26 | Whenever a Delivery Group contains special characters, clicking on any Application or Application Details tab produces error "An error occured while parsing EntityName". | Remove the special characters from each Delivery Group that contains them. | https://support.citrix.com/article/CTX226068 | |
| 27 | Anonymous/unathenticted users are disconnected after being idle for 10 minutes, even after increasing the idle limit value. This behaviour is not experienced on VDA 7.8 or below. | Change the value of "AnonymousUserIdleTime" to "0" in the registry. | Citrix VDA 7.9. | https://support.citrix.com/article/CTX225958 |
| 28 | XenApp 7.6 VDAs randomly stop accepting new ICA or RDP connections. RDSWatcher shows that a new connection gains the username of an existing connection. | This is caused by Res Appguard preventing "Winlogon.exe" from accessing "dwm.exe". An exception should be made within Res Appguard. | https://support.citrix.com/article/CTX203519 | |
| 29 | Session begins to launch but then ends straight away with no specific error. | Check your Citrix licenses to make sure they have not expired or exceeded the amount. | ||
| 30 | Desktop option greyed out when creating a Delivery Group. | Check the license model and if it is set to XenApp, change it to XenDesktop. | https://support.citrix.com/article/CTX218251 | |
| 31 | VDA stuck on "Welcome Screen". | Install KB2878182. | https://support.citrix.com/article/CTX224607 | |
| 32 | When editing policies on Wnidows Server 2012 R2 the mmc crashes upon clicking "Citrix Policies". | This is caused by a missing assembly from Visual C++. Install Visual C++ 2015 Redistributable x64. | https://support.citrix.com/article/CTX225741 | |
| 33 | Reboot schedules no longer work after upgrading Delivery Controller to 7.13. | Remove the reboot schedule via PowerShell and then create it again via Citrix Studio. If that does not work recreate the Machine Catalog. If that also does not work, contact Citrix support. | https://support.citrix.com/article/CTX225785 | |
| 34 | Workspace Control may stop working and reconnection attempts hand at "Welcome Screen" before failing. | This only seems to occur when using VMware App Volume Manager. On the VDA, vhange the value of "SessionInPreLogoff" from "0" to "1" in the registry. | https://support.citrix.com/article/CTX225625 | |
| 35 | Applications do not enumerate in StoreFront 3.9 using SAML with ADFS and NetScaler. | You need to implement Citrix Federated Authentication Service on StoreFront. This is the only supported option when using SAML authentication. | Citrix XenApp and XenDesktop 7.9 and StoreFront 3.6. | https://support.citrix.com/article/CTX220993 |
| 36 | The first time a user saves PDF files to a client drive via Client Drive Mapping it works, however subsequent attempts fail with error "File in use". | Upgrade to XenApp/XenDesktop 7.13. This has also been resolved in XenApp/XenDesktop 7.6 CU3 LTSR. | Citrix XenApp 7.8 to 7.12. | https://support.citrix.com/article/CTX220268 |
| 37 | You experience slow reconnection and logons to Windows Server 2012 R2 VDA. | Create "GpoCacheEnabled" DWORD with value "1" and "CacheGpoExpireInHours" DWORD with value "5" under "HKLM\SOFTWARE\Citrix\GroupPolicy" | https://support.citrix.com/article/CTX218734 | |
| 38 | Lauching a second application in "Fixed Window Mode" fails with error "Application Name is currently unavailable. Try reconnecting and if the problem persists, contact your system administrator". | Citrix XenApp 7.x does not support multiple application sessions from the same Delivery Group in Fixed Window Mode because Session Sharing only supports seamless application sessions. There are workarounds available. Either separate applications in to multiple Delivery Groups or in XenApp 7.9 and above, create an Application Group and disable Session Sharing. | Citrix XenApp 7.6 to 7.9. | https://support.citrix.com/article/CTX214532 |
| 39 | Unable to delete desktops from Machine Catalog due to error "The uuid is invalid". | If a VM is deleted from the Hypervisor directly, the Virtual Machines UUID in the Site database will no longer be valid. Attempting to delete that Virtual Machine through Citrix Studio will fail due to the UUID not being validated. Run the "Remove-BrokerMachine" PowerShell command manually to remove these machines. | https://support.citrix.com/article/CTX223187 | |
| 40 | Personal vDisk enabled VMs fail to registry with a Delivery Controller with Citrix Studio returning agent error code 6 "The Personal vDisk could not find a disk attached to the system for storing user data". | The Personal vDisk service prevents registration of a VDA with the Controller until the PvD successfully initializes. This is to ensure that users are not connected to the desktop before the PvD is fully functional. Verify the PvD disk is attached to the Virtual Machine. Make sure the GUID marker file exists at the root of the PvD disk and that the file can be read. | https://support.citrix.com/article/CTX225302 | |
| 41 | VDA reboots after a few minutes of being online after migration from one Citrix Site to another. The device appears as Unregistered in Citrix Studio the whole time. | The VDA still has the old list of Delivery Controllers under "C:\Program Files\Citrix\PvsVm\Service\PersistedData\BrokerAgentInfo\SavedListOfDdcsSids.xml". Uninstall the VDA using the VDA Cleanup Utility and then install again. | https://support.citrix.com/article/CTX225199 | |
| 42 | When launching a published desktop you receive error "There is a time and/or date difference between the client and server". On the Delivery Controller Event Log shows errors such as "The Citrix Broker Service failed to validate a user's credentials on an XML service" and "Verify the trust relationships between your domains". | Make sure the correct time is configured on each Delivery Controller and Domain Controller. | https://support.citrix.com/article/CTX225029 | |
| 43 | XenApp and XenDesktop catalogs can stop performing as expected after you change the name of storage, network or datacentre paths on your Hypervisor *after* you have created the Hosting Connection and Machine Catalogs. This mostly occurs with MCS but can also be found on PVS. | As of XenApp or XenDesktop 7.13, this version updates all hosting related objects if you rename the storage, network or root paths in your Hosting Connection. If you install 7.13 fresh no additional work is required. If you are upgrading from a previous version which contains existing Hosting units, you need to recreate them. | https://support.citrix.com/article/CTX225019 | |
| 44 | Policies do not apply against certain Delivery Groups. | This happens if you delete a Delivery Group and then recreate with the same name. Remove and re-apply the policy filter. | https://support.citrix.com/article/CTX224905 | |
| 45 | Citrix Receiver crashes when launching a published application within a published desktop double-hop scenario. You receive error "Citrix HDX engine has stopped working" and then Receiver crashes. Event Viewer logs Event ID 1000 with crashing process "Wfica32.exe". | Upgrade the VDA to 7.14. | Citrix XenApp 7.12 to 7.13. | https://support.citrix.com/article/CTX224890 |
| 46 | Webcam redirection does not work with Windows N and KN editions. | Web cameras do not work for these editions of Microsoft Windows. | Windows 7, Windows 8 and Windows 10 N or KN editions. | https://support.citrix.com/article/CTX224830 |
| 47 | When dragging a window you receive lag. | Try disabling policy setting "View window contents while dragging" and make use of the lossless switch (available for HDX 3D Pro enabled VDAs). | https://support.citrix.com/article/CTX224826 | |
| 48 | You receive a "ConnectionValidationFailure" when attempting to create a host connection to SCVMM. | The required SCVMM DWORD port value is missing. On each Delivery Controller, create a DWORD with name "IndigoTcpPort" and value "8100" under "HKLM\SOFTWARE\Microsoft\Microsoft System Center Virtual Machine Administrator Console\Settings". | https://support.citrix.com/article/CTX224741 | |
| 49 | Power Managed Server VDAs randomly receive a shutdown request approximately 20 minutes after the scheduled reboot and remain turned off. You must then manually power them back on. | This may be due to the affected VDAs not registering with a Delivery Controller within 20 minutes. You will see Event Viewer logs such as "The Citrix Broker Service marked a power action as failed because virtual machine ... failed to register with the site after being started, restarted or resumed". You may have to change the "MaxRegistrationDelayMin" timeout or investigate why these VDAs are failing to register. You could also spread the VDA reboots out over a larger timeframe. | https://support.citrix.com/article/CTX223434 | |
| 50 | When launching a published application the session begins to connect but then dissapear after a few minutes. | This may be because the session cannot fully complete its launch before the default application launch timeout period value. By default this timeout is 1 minute. On each VDA, create an "ApplicationLaunchWaitTimeoutMS" DWORD to increase this timeout value. | https://support.citrix.com/article/CTX224596 | |
| 51 | As a user logs off a published Internet Explorer, the session remains active in the back-end. | This can be caused by one of the Internet Explorer processes created for ACR (Automatic Crash Recovery) hanging. You can force Internet Explorer to execute a single process by setting the "TabProcGrowth" string to "0" in registry. | https://support.citrix.com/article/CTX224600 | |
| 52 | You receive error "Can't connect to this camera. Close any active conversations or other programs that are using your camera, and then try again". | Video compression for 64-bit applications is not supported on the VDA. You must use 32-bit applications if you wish to use video compression with them via H.264. | https://support.citrix.com/article/CTX224617 | |
| 53 | When creating a Machine Catalog you receive exception "0x80005000". | As a workaround you can upgrade to XenApp or XenDesktop 7.15 LTSR. | Citrix XenApp and XenDesktop 7.8. | https://support.citrix.com/article/CTX224616 |
| 54 | Black screens may flash or appear steadily across the desktop when interacting with controls in custom published applications. | Certain applications create an invisible full-screen window and in this case a full-screen black window is created for this window. As you interact with the published application, the "CompatWindowDesktopReplacement" seamless window may gain focus and cover the client desktop with a full screen black window. You can resolve this issue by setting per window class seamless flags in the registry of each VDA as described in the CTX article. | https://support.citrix.com/article/CTX224513 | |
| 55 | With Adaptive Transport enabled, you receive a "Connection Interrupted" message from Receiver when working from a high latency network. | This happens due to network fragmentation. Reducing the UDT MSS to a smaller value will resolve the problem. The default value for UDT MSS is 1500. You can modify the default UDT MSS value by firstly consulting with your network team to find the right value and then editing the "default.ica" file on StoreFront. | https://support.citrix.com/article/CTX224373 | |
| 56 | In a multi-domain environment, a child domain user receives error "You have not been granted access to this published application" when attempting to launch an application from StoreFront. | This happens when the published applications "Limit Visibility" setting is configured for a child-domain user group and that user-group name exists in another child or parent domain. Either change the group names so that there is no duplicates across domains, add users to "Limit Visibility" instead of groups, create a Universal Security Group, contact Citrix for a private fix for 7.12/7.13 or upgrade to XenApp and XenDesktop 7.15 which contains the fix. | Citrix XenApp and XenDesktop 7.13 to 7.15. | https://support.citrix.com/article/CTX224290 |
| 57 | Machines fail to register with any Delivery Controller after a scheduled reboot. | Set DWORD "MaxTimeBeforeStuckOnBootFaultSecs" and "MaxTimeBeforeUnregisteredFaultSecs" to a value of "3000". This gives the VDAs more time to registry after a reboot. | https://support.citrix.com/article/CTX224308 | |
| 58 | Session launch is stuck at "Connection established. Negotiating capabilities". | This issue occured after anti-virus definition updates and was resolved by disabling Trend anti-virus. | Citrix XenApp 6.5 for Windows Server 2008 R2. | https://support.citrix.com/article/CTX224309 |
| 59 | Email toast notifications do not appear when Outlook is published as a seamless application. This affects both Outlook 2013 and 2016. | Due to a limitation of the Metro UI in Windows Server 2012 R2, toast notifications in Outlook 2013/2016 are not supported in XenApp 7.x. Microsoft anticipated that this issue would be resolved in Windows Server 2016 but it does not appear to be. | Windows Server 2012 R2 or Windows Server 2016 with Outlook 2013 or 2016. | https://support.citrix.com/article/CTX214638 |
| 60 | When connecting to VMware an error "TLS Error Prevented Connection to the Hypervisor, Not All SSL Details Could be Validated" appears. | Upgrade to XenDesktop 7.8. | Citrix XenDesktop 7.7. | https://support.citrix.com/article/CTX212870 |
| 61 | When disconnecting a session using the disconnect button on the Start Menu you receive error "The network connection to your application was interrupted. Try to access your application later, or contact your help desk". | This is a known issue. Contact Citrix support. | Citrix XenDesktop 7.12 and 7.13. | |
| 62 | When logging on to StoreFront you receive error "Please verify your user name and password and try logging on again. If you cannot log on, contact your help desk". | This can happen due to a timeout between StoreFront and the Delivery Controller when attempting to authenticate the user via XML authentication. Try increasing the timeout value of "XmlWpnbrRequestTimeoutMs" to "90000" on each Delivery Controller. | Citrix XenDesktop 7.13. | https://support.citrix.com/article/CTX223750 |
| 63 | Adaptive Transport or Framehawk might fall back to TCP. | This can be caused by stale entries in DNS for the NetScaler Gateway Virtual Server on a client machine. Flush the DNS cache on client machine and reconnect. | ||
| 64 | When logging on or off a Windows 10 or Windows Server 2016 VDA, the operation may pause and appear to be hung. | Click in the session window to resume the operation. | Citrix XenApp and XenDesktop 7.14. | |
| 65 | When Local Host Cache is enabled, users with desktop connections may not be able to reconnect during an outage. | Restart the Citrix High Availability Service. | Citrix XenApp and XenDesktop 7.14. | |
| 66 | CtxAuth (Citrix Kerberos Authentication) does not work for Windows Server 2016 VDAs that have "KB3213986" installed. | Upgrade to VDA 7.14. | ||
| 67 | On 64-bit Firefox browsers with the "Electrolysis" or "e10s" feature enabled, unexpected terminations occur. | Upgrade to XenApp or XenDesktop 7.14 to resolve the Firefox terminations or contact Citrix Support for a private fix for older builds. You could also disable Citrix API hooks for Firefox. To resolve Chrome, create an "ExcludedImageNames" string with value "chrome.exe,nacl64.exe". | Citrix XenApp 6.5, XenApp 7.x or XenDesktop 7.x. | https://support.citrix.com/article/CTX224067 |
| 68 | Users are unable to launch desktops or applications after a XenApp or XenDesktop database is set up for mirroring. The Delivery Controller's event logs record "An unexpected exception occured while the Citrix Broker Service processed an HTTP request". | Either remove mirroring or update all FMA service connection strings to reflect the new failover SQL partner. | https://support.citrix.com/article/CTX224035 | |
| 69 | Running a basic search in Studio may be slow or time out. | This is due to a large deployment containing a substantial amount of data and lack of selectivity in the search query. You should use the advanced search options to increase selectivity and target the SQL database more precisely and efficiently. | Citrix XenDesktop 7.6 to XenDesktop 7.13. | https://support.citrix.com/article/CTX223990 |
| 70 | Client-side content fetching does not work when accesing a video using the "mms" protocol. When accessing the same video via HTTP, client-side content fetching works. | When video is played back using the mms protocol, Windows Media Player loads and uses an original DirectShow source filter which interferes with cleint-side content fetching. Instead, continue to access videos on a web server via HTTP. | https://support.citrix.com/article/CTX223982 | |
| 71 | After a XenDesktop and PVS upgrade, the XenDesktop Setup Wizard in PVS does not list existing catalogs that were created before the upgrade. | Upgrade existing Machine Catalogs to the latest functional level or else run the PVS XenDesktop Setup Wizard choosing a lower functional level when asked. | Citrix XenApp and XenDesktop 7.6/7.8. | https://support.citrix.com/article/CTX223899 |
| 72 | XenDesktop 7.x Site creation fails with error "XDDS:7205050FF6" and in Event Viewer ID 1000 is logged with error "0xc0000005". | Upgrade SQL to the latest service pack, run a repair/reinstall of SQL and make sure the instance is configured properly and all services are up. | https://support.citrix.com/article/CTX223896 | |
| 73 | Citrix Studio shows the incorrect site name. | Open file "Studio" found in "%AppData%\Microsoft\MMC\" and search for the incorrect site name, replacing it with the correct site name. | https://support.citrix.com/article/CTX216268 | |
| 74 | Dragging windows inside of a seamless published application may show in some instances the window contents or background colour of the server VDA. At other times the window will appear to snap into place once the mouse button is released. This may make you believe that the "View window contents while dragging" policy is not behaving as expected. | This is expected behaviour as you are dragging content from within the server rather than dragging content from the client window that Receiver handles. | https://support.citrix.com/article/CTX223876 | |
| 75 | Logons hang at "Please wait for Citrix Profile Management". | Make a copy of the vDisk and mount it to a machine, load the System Registry hive and set service "Citrix Telemetry Service" startup to "Automatic (Delayed Startup)". | https://support.citrix.com/article/CTX219468 | |

| 95 | Session launches but then the progress bar dissapears with no error message. | This happens when multiple nested AD groups are used to assign access to Citrix applications and desktops. This is not recommended by Citrix. Avoid nested groups and instead add users directly to a single group and use that group against your Delivery Groups. | https://support.citrix.com/article/CTX216005 | |
| 96 | Logon scripts are delayed by up to 5 minutes on Windows 8.1 or Windows Server 2012 VDAs. | Using Group Policy, disable "Configure Logon Script Delay" if you do not require a delay in running logon scripts. The default delay is 5 minutes and was introduced by Microsoft to provide faster logons. | https://support.citrix.com/article/CTX200190 | |
| 97 | When launching a published application you receive error "Access denied" during Windows logon. This only happens to certain users. | This can be caused by the user being a member of a large number of groups in Active Directory. Create a DWORD with name "MaxTokenSize" and decimal value "48000" under "HKLM\System\CurrentControlSet\Control\Lsa\Kerberos\Parameters". | https://support.citrix.com/article/CTX138329 | |

Either provide the Studio machine with internet access or uncheck "Check for publisher's certificate revocation" within Internet Explorer properties. | https://support.citrix.com/article/CTX139325 | |
| 104 | When an idle timeout is reached on Windows Server 2012 VDAs, the "Idle timer expired" message to indicate that the session has been idle over its time limit does not display in ICA sessions. | Microsoft have been engaged to help fix this issue on Windows Server 2012. | Windows Server 2012. | https://support.citrix.com/article/CTX222445 |
| 105 | On Server OS VDAs, the Load Index shows "10000" in Citrix Studio. This happens shortly after configuring the "Memory usage" Studio policy. | This was caused by base OS performance counters being disabled on the VDA. Open "Perfmon" and attempt to add the Memory related performance counters such as "Available MBytes" and "Cache Faults/sec". If you can't it's likely performance counters are disabled via registry. | https://support.citrix.com/article/CTX218335 | |

| 108 | After upgrading to Firefox 52 you can no longer launch applications. | NPAPI plugin support was removed in Firefox 52. You can either use an extended support release for Firefox 52. Alternatively StoreFront 3.8 and 3.9 can be edited to enable Citrix Receiver launcher as a workaround. StoreFront 3.11 enabled Citrix Receiver launcher by default. | https://support.citrix.com/article/CTX221551 | |
| 109 | When attempting to launch a published application via Receiver for Web, nothing happens. | This issue was caused by the web browser process and "wfica32.exe" running on different integrity levels which resulted in COM problems. | https://support.citrix.com/article/CTX221707 | |

| 114 | ICA sessions get stuck at prelogon and Citrix Studio/Director shows a blank Current User or Associated Username. Running "Get-BrokerSession" from PowerShell shows the session as being in the prelogon state. The VDA machined in Event Viewer show ID 1011 "The remote session could not be established from remote desktop client xxxxx because its temporary license has expired". | This can be caused by an incorrect configuration of Remote Desktop licensing. For example, if you have purchased "Per User" CALs but the Remote Desktop Licensing Mode is set to "Per Device". | Citrix XenDesktop 7.8. | https://support.citrix.com/article/CTX219511 |
| 115 | The Citrix Desktop Service fails to start on each VDA with Event Log logging ID 7000 error "The service did not respond to the start or control request in a timely fashion". | This issue can be caused by slow system startup which prevents the Citrix Desktop Service from starting within 30 seconds and therefore timing out. It could also be caused by hypervisor load, too many VDAs rebooting at once or network issues. As a workaround, you can set the startup type to "Automatic (Delayed Start)" or increase the services timeout value from 30 seconds to a value such as 45 by modifying the "ServicesPipeTimeout" registry DWORD. | https://support.citrix.com/article/CTX119421 | |
| 116 | When adding a new Delivery Controller to your Site you receive error "Error ID: XDDS:1E9F32BB" and "Failed to update database 'databasename' on server 'domain\server'". | This can happen if the same Controller was previously added to the SQL database with the same hostname but different SID and not removed properly from the Site database.

| 133 | When launching a desktop through Receiver for Web, Desktop Viewer quits after reaching the CTRL+ALT+DEL screen. | On each VDA, disable autologon by setting "EnforceAutoLogon" DWORD to "0" under "HKLM\Software\Policies\Citrix". | https://support.citrix.com/article/CTX227562 | |
| 134 | After replacing expired SSL certificates on your Delivery Controllers, you find that StoreFront Event Logs show ID 4003 and Event ID 0 due to the DDCs continuing to offer the expired certificate. | This is because the old certificate's thumbprint is still bound to the HTTPS port on each Delivery Controller. You need to use "netsh" to bind the new certificate thumbprint against port 443 on each Delivery Controller. | https://support.citrix.com/article/CTX227572 | |
| 135 | Cannot install VDA due to a print spooler service error. | Make sure the Print Spooler service is started on the Server OS VDA. Failure of the service can cause issues during VDA install. | ||
| 136 | VDA shows as unregistered due to an incompatible OS.

| 447 | Trying to launch a published application from within a published desktop (double hop) causes a new published desktop session starting with the published app running, and an "Access Denied" message showing in the background. | A number of Citrix related registry values were missing and needed to be created, as shown in the CTX article. | https://discussions.citrix.com/topic/403168-strange-published-app-behavior-in-remote-desktop/ | |
| 448 | When launching a published application Receiver or Workspace app hangs at "Please wait for the Local Session Manager".

| 449 | Odd numbered VDAs all appear with a "Power State" of "Unknown" and they do not accept connections. Even numbered VDAs are fine. | Rebooting the VDAs solved this issue. | ||
| 450 | With multiple monitors in use, the mouse pointer is being pushed outside of the publsihed application window. | Setting the resolution on each monitor to be the same as the laptop resolved the issue. | ||
| 451 | A Windows Defender update released by Microsoft breaks broker communication as it detects the "Citrix Broker Service" and "Citrix High Availability Service" as trojans and removes the files associated with those services. | This occurs when Windows Defender is installed on Delivery Controllers. There are three workarounds available in the CTX article, such as disabling/downgrading Windows Defender, or restoring the missing files including excluding them from Windows Defender. | https://support.citrix.com/article/CTX279897 | |
| 452 | After launching a published application, the window of the application cannot be expanded to cover the entire screen, and a large portion of the application window is filled by a black box. | This was caused by a docking station, or the external monitor connected to it. After disconnecting the docking station, the application window displayed normally. | ||
| 453 | When opening Studio you receive message "Is your License Server compatible? Your License Server must be compatible with this upgrade to make sure that users can access their applications and desktops". However, no upgrade has been performed. | A service stuck on any of the Delivery Controllers can cause this. On each Delivery Controller, launch PowerShell and run cmdlet "Get-Command Get-*ServiceStatus" followed by running all of the returned cmdlets such as "Get-ConfigServiceStatus". Check the output of each cmdlet returns "OK". If any return "DBUnconfigured" then reboot the affected Delivery Controller and recheck. If the cmdlet continues to return DBUnconfigured, you can configure it manually using for example "Set-ConfigServiceStatus". | ||
| 454 | VDAs reboot out of schedule just after midnight before daylight savings time ends. | Upgrade to Virtual Apps and Desktops 7.15 LTSR CU6, 1912 LTSR CU1, or Virtual Apps and Desktops 7 2003 and newer versions. | Citrix Virtual Apps and Desktops 7.15 LTSR before CU5, 1912 LTSR before CU1, and Current Release before 2003. | |
| 455 | Users fail to enumerate and launch published resources, and VDAs may attempt to re-register with Delivery Controllers. The Delivery Controllers may also log Event ID 1200 and 1201 "The connection between the Citrix Broker Service and the database has been lost". Running "Get-BrokerServiceStatus" from Delivery Controllers may return "PendingFailure". This happens because many access requests to the "Chb_State.Sessions" SQL table are blocked. | This is resolved in Virtual Apps and Desktops 1912 LTSR CU2. Otherwise, you can reach out to Citrix support to obtain a fix by referring to bug ID "CVADHELP-14876". | https://support.citrix.com/article/CTX286221 | |
| 456 | Server VDAs do not complete a reboot and are left in a powered off state. | Set the "MaxShutdownTimeSecs", "MaxShutdownDelayMin" and "ShutdownTimeoutRecovery" DWORD values to decimal "20", "60" and "1" respectively as outlined in the CTX article. | https://support.citrix.com/article/CTX237058 | |
| 457 | After an upgrade to 1912 LTSR CU2, the Azure Hosting connection may fail to work. When using the "Test Connection" feature you receive error "Error Id: XDDS:D2089BCC". | Upgrade .NET Framework to 4.7.2 or higher. Citrix is working on incorporating the .NET Framework 4.7.2 install into the Virtual Apps and Desktops meta-installer in a future release. | Citrix Virtual Apps and Desktops 1912 LTSR CU2. | https://support.citrix.com/article/CTX292869 |
| 458 | Upgrading VDA 2003 to 2009 or 2012 fails with error "1721" and "Windows Installer installed the product. Product Name: Citrix Monitor Service VDA Plugin. Product Version: 7.28.0.11. Product Language: 1033. Manufacturer: Citrix Systems, Inc. Installation success or error status: 1603.". | Follow the steps in CTX article such as adding new System variables, running the VDA cleanup utility, and then retrying an install. | https://support.citrix.com/article/CTX292909 | |
| 459 | With URL redirection configured, particular users working remotely click on URL links within published apps, however the web page attempts to load through the client's local browser and subsequently fails. | This issue affects Virgin Media (UK) broadband customers. Opting out of ANES (Advanced Network Error Search) resolves the issue. | ||
| 460 | Citrix Site upgrade from 1903 to 2103 gets stuck in a loop and the upgrade fails with error "Update requires all services to be stopped" or "Update requires all Citrix Broker service instances to be stopped" until you stop services "Citrix Host Service", "Citrix Broker Service", and "Citrix Machine Creation Service". | Rolling back the upgraded Delivery Controllers and restoring the Site database, and then attempting the upgrade again resolved the issue. | ||
| 461 | User profiles are not being deleted at logoff. Upon investigating, some folders under "%LocalAppData%\Microsoft\Windows\WER" are locked and cannot be deleted. | Symantec Endpoint Protection was found to be causing this issue. The issue is resolved in version 14.3 RU1 and above. There is also a workaround posted in the linked article. | https://knowledge.broadcom.com/external/article/184245/endpoint-protection-142-prevents-termina.html | |
| 462 | Applications launch with a black screen. | Updating the graphics card drivers on the machine experiencing the issue resolved this. | ||
| 463 | When copying data from a published application or desktop to the local endpoint, the data can become corrupt or appear to lose its formatting. | This appears to be an issue affecting the VDA. Upgrade to 2106. | Virtual Apps and Desktops 7 2103. | |
| 464 | VDAs fail to register with any Delivery Controller and log Event ID 1023 "The registration was refused due to 'AgentNotContactable'". | Add each Delivery Controller to the "Access this computer from the network" policy, which can be controlled via Group Policy. | ||
| 465 | When connecting to a Virtual Delivery Agent running 2112, you receive a Windows Firewall popup on your client asking if you want to allow access for "Citrix HDX Engine". | Only occurs when the VDA is version 2112. You can allow access if you have the elevated rights. | Citrix Virtual Apps and Desktops 7 2112. | |
| 466 | Mac users experience the Citrix Viewer crashing and session connection issues. | Citrix Virtual Apps and Desktops 7 2203 and older versions. | ||
| 467 | Microsoft 365 build 16.0.7967 and later when published as applications from a Windows Server 2019 Virtual Delivery Agent may freeze after a user enters their email address as part of the license activation prompt. | This is resolved in VDA versions 2203 CU1 and above. Upgrade to 2203 CU1, create a 'Shellbridge' DWORD with value '0x1' under 'HKLM\SOFTWARE\Citrix\Citrix Virtual Desktop Agent' and ensure Microsoft KB5014022 is installed on the VDA. | ||
| 468 | When attempting to remove the VDA component you receive message "There are no components available to remove". | From a Process Monitor trace the uninstall was trying to reference VDA media from a remote share to execute the uninstall and the share no longer existed. Changing all registry values to the equivalent local path where the VDA media resided resolved the issue. | ||
| 469 | After launching a Citrix session a blank white screen is displayed. | Creating a 'UseSoftwareOnlyRendering' DWORD with value '0x1' under 'HKLM\SOFTWARE\WOW6432Node\Citrix\Dazzle' resolved the issue. | https://support.citrix.com/article/CTX484461 | |
| 470 | After upgrading the VDA software the machines in Studio show as unregistered due to "Registration Missing". | The command "LODCTR /R" was run twice on each of the affected VDAs and then the Citrix Desktop Service restarted. This resets the counters. | ||
| 471 | A Server OS VDA running version 2203 or 2206 may experience a BSO with BugCheck code 0x0000007e due to an access violation by tdica.sys. | The issue has been resolved in Citrix Virtual Apps and Desktops 2209 and 2203 LTSR Cumulative Update 2. | Citrix Virtual Apps and Desktops 2203 and 2206. | https://support.citrix.com/article/CTX463756/2203-or-2206-server-os-vda-may-experience-bsod-on-tdicasys |

November 26, 2020Hi,
We see one of the problem too. Every time the hosting connection has a problem an maschine goes to power state “unknown”, then we are not able to get a connection to multi-session hosts. Any idea ? We see that with LTSR 1912 (CU1 + CU2). A reboot still bringing up the machine with “unknown” does to fix the problem of no connection.
Regards
Reinhard

March 29, 2021From a delivery controller run get-brokerhypervisorconnection determine the preferred controller, from that preferred controller restart the citrix host connection service. I see this occasionally as well. This normally fixes the unknown power state.

March 23, 2021If you see servers with power state unknown log on to DDC server , open powershell as administrator and paste commands below one by one]
asnp Citrix*
Get-Service Citrix* | Stop-Service -Force
Get-Service Citrix* | Start-Service
citrix asnp*
If it doesnt fix the issue, try executing it on all DDC.
