Slow Logons in XenApp Sites with Read-Only Domain Controllers

Symptoms

Users experience slow logons on sites with Read-Only Domain Controllers (RODC). Administrators may also notice a spike in processor usage by winlogon.exe for up to 30 seconds.

Cause

The existence of Read-Only Domain Controllers is causing Active Directory Service Interface (ADSI) calls to take a long time, which in turn is causing a slow logon and winlogon to spike.

Workaround

Switch away from Read-Only Domain Controllers on the site where you are experiencing the issue.

Resolution

Citrix have diagnosed the root-cause behind this issue, and a Private fix is available for XenApp 5, XenApp 6, and XenApp 6.5. As this fix is still a private fix, you must contact Citrix Support to obtain a copy of this.

Please quote CPR Ref: LA1617 when contacting support to assist with locating the correct fix.

Provisioned XenApp Servers do not Accept Connections

Provisioned XenApp servers do not accept connections when restarted while the license server is unavailable.

Requirements
  • Provisioned XenApp servers
  • XenApp 6.0
  • License Edition 11.9
Background

The license server cache file, MPS-WSXICA_MPS-WSXICA.ini, is saved in the %systemroot%Program FilesCitrix folder, which might be unavailable when the server image shuts down and Provisioned XenApp servers refuse to accept connections when they are restarted while the license server is unavailable.
Procedure
The following are the steps to complete the task:

Save the license server cache file in a shared network location – a location separate from the XenApp server image so that the file is available even when the server image shuts down.
If you save the file in a location away from the server image, you must set the following registry key to point to the cache file location:
Caution! This fix requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.” Continue reading “Provisioned XenApp Servers do not Accept Connections”
