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

The
System.ServiceModel.ChannelFactory1communication object _[<object name>_]cannot be changed while its state is Opening.[CVADHELP-15801]
-

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]
-

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]
-
This fix addresses performance issues you might experience with Delivery Controller (XML service) in slow active directory environments.
To enable the fix, set the following registry key:
HKEY_LOCAL_MACHINE\Software\Citrix\DesktopServer
Or
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]
-

$trueto$falseon 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:

[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]
-
