Azure, AWS, Citrix XenApp Essentials and XenDesktop Essentials:


wdt_ID Brief Description of Issue Brief Description of Fix Applicable Product Versions Affected (if known) Link to supplemental Support Article(s)
1 In a multi-zone XenDesktop site, the DDC in Azure fails to connect to an on-premise DDC. VDAs in Azure are also listed as unregistered. Set the primary domain controller (PDC) as the primary time source for the domain and enable the PDC to sync its time with an external reliable time source. https://support.citrix.com/article/CTX206522
2 VDAs in Azure are powering up, registering and then powering off again. This process continues as a reboot cycle. Users can not launch applications as a result. The Cloud Connectors were running Windows Server 2016. Installation of MS Hotfix KB4025339 resolves the issue. https://support.citrix.com/article/CTX226240
3 The creation, updating and deletion of MCS Machine Catalogs from Azure Resource Location fails. Running a Host Connection test and Resources test results in error message "Contact Citrix Support". A CDF trace on the Delivery Controller shows an exception when trying to enumerate the Azure Storage Account details. This was caused by an earlier Azure outage resulting in missing tags. Add the missing tags manually to the Azure Storage Account. MCS Storage Account on Azure was missing the tags required for MCS to work correctly. https://support.citrix.com/article/CTX222848
4 You have configured Azure AD for XenApp Essentials however when users log on to StoreFront they receive error "There was a failure with the mapped account". This means that the user account has not yet synchronised from your on-premises Active Directory to Azure AD. The synchronisation process can take up to 2 hours. https://support.citrix.com/article/CTX227065
5 When trying to link Azure subscription to a catalog, you get a message that the subscription has already been linked, however the subscription does not show in Azure subscription tab. This is due to lack of premissions on Azure for the XenApp Essentials service and the account adding the subscription. https://support.citrix.com/article/CTX226977
6 Machines in Azure are not being started fast enough to cover increased user load. Support for Azure ARM is continually improving. One of the new features is on demand provisioning of virtual machines. To take advantage of this benefit, recreate your machine catalogs. https://support.citrix.com/article/CTX227833
7 Azure NV6 series machines deployed via MCS encounter a reboot loop. Citrix are investigating this issue. In the meantime, when creating a Machine Catalog do not enable Write Cache. https://discussions.citrix.com/topic/393726-azure-mcs-nvidia/
8 VDAs in Azure that use Adaptive Transport may freeze every 5-15 minutes. The EDT MSS must be reduced to 1400 or lower. Packets greater than 1420 may be dropped in Azure. https://discussions.citrix.com/topic/391703-edt-adaptive-transport-with-azure-netscaler/
9 You cannot create more than 240 machines in an Azure resource group. An Azure resource group can only accomodate 800 disks. The Machine Creation Services process creates three disks per machine. The XenDesktop design creates 240 machines per resource group. https://support.citrix.com/article/CTX237504
10 You cannot update a Machine Catalog hosted on AWS. A CDF trace shows error "IpRange is malformed". AWS recently enabled IPv6 security group rules by default which caused this issue. Removing the outbound rules solved it. https://support.citrix.com/article/CTX239201

    HI

    I am getting error “There was an failure with the mapped account”.
    I have on prem AD and xenapp is installed on client machine.
    As per above mention issue it is due to unsynchronised AD users, can you please explain how we can forcefully sync the user in xenapp.
