Citrix Virtual Apps and Desktops

Fixed issues

The following issues have been fixed since Citrix Virtual Apps and Desktops 7 1912 LTSR CU2:

Citrix Director

  • After uninstalling a VDA, the namespaces for Citrix Windows Management Instrumentation (WMI) might remain. [CVADHELP-14965]

  • Citrix Director might intermittently display the following alert on the Delivery Controller:

    The System.ServiceModel.ChannelFactory1 communication object _[<object name>_] cannot be changed while its state is Opening.

    [CVADHELP-15801]

  • On the Historic Machine Utilization page, data in the Top 10 Processes table might not be displayed. This message appears:

    Process data collection is disabled on this machine. Enable process monitoring policy to start collection.

    [CVADHELP-15893]

  • On the Director > Trends > Logon Performance > Export Report page, when you generate and export a report, incorrect brokering time values might appear in the report. The issue occurs with the German language report where . is replaced with ,. [CVADHELP-16097]

  • On the Director > Filters > All Machines page, if you select a machine and then perform maintenance operations, check marks might not be retained for the selected machines. [CVADHELP-16469]

  • When extracting process data from the Monitor API, invalid data might appear. The process creation time (ProcessCreationDate) appears after the process collection time (CollectionDate) instead of appearing before. [CVADHELP-17092]

Citrix Policy

  • When you upgrade the Citrix Group Policy Engine from Version 1.7 to Version 1912 LTSR, the Printer assignments policy under Citrix User Policies might not be displayed. [CVADHELP-15608]

Citrix Provisioning

Citrix Provisioning 1912 CU3 documentation provides specific information about the updates in this release.

Delivery Controller

  • Attempts to restart a Delivery Controller might cause all connected VDAs to unregister in multiple domains. [CVADHELP-12840]

  • When you send authentication requests to the XML Service on a Delivery Controller by using certain third-party application services, performance issues might occur.

    To enable the fix, set this registry key as follows:

    HKEY_LOCAL_MACHINE\Software\Policies\Citrix\DesktopServer

    Name: DisableGetPasswordExpiryInfo

    Type: DWORD

    Value: 1

    [CVADHELP-15536]

  • With this fix, the preparation machine does not use the default cache expiration time (five minutes). The fix provides the following:

    • Reduces the expiration time of a machine with an unknown power state (one minute).
    • Reduces the expiration time of a preparation machine that is transitioning power (five seconds)
    • Reduces the expiration time of a preparation machine that is not transitioning power (one minute).
    • Reduces the expiration time of a non-preparation machine that is transitioning power (30 seconds).

    [CVADHELP-15678]

  • When you use PowerShell to perform a power action, the action might be processed successfully, but the action is logged as failed in Citrix Studio > Logging. [CVADHELP-15807]

  • When you delete machines or catalogs associated with an AWS hosting connection, EBS root devices might not be automatically deleted. The issue occurs because the flag DeleteOnTermination on the base image changes from $true to $false on disks created for those catalogs during machine catalog creation. [CVADHELP-16096]

  • In a multi-zone environment with high latencies, attempts to upgrade XenApp and XenDesktop version 7.15 LTSR CU5 to Citrix Virtual Apps and Desktops version 1912 CU1 might fail with the following exception:

    NullReferenceException

    [CVADHELP-16236]

  • On a Delivery Controller, the following error message might appear frequently in Event Viewer > Windows Logs > Application:

    Event ID 505: The Citrix Config Sync Service failed an import

    [CVADHELP-16322]

  • Signing in to an unbrokered RDP session with a UPN credential might result in an uncaught exception. In 1912 LTSR CU2, a name translation for usernames provided as UPN was introduced. The truncation of the username due to the limit imposed in RDS data structures produces an incorrect username, resulting in the uncaught exception. [CVADHELP-16510]

  • When you launch a VM hosted app and then attempt to launch a second VM hosted app from the same VDA, the launch might fail. The issue occurs when the machine catalog uses the static allocation. [CVADHELP-16829]
