Important Notes

  • Caution: Several items in this hotfix rollup pack require 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.
  • Skype might not recognize the camera, in which case the video portion of the Skype call is missing. To avoid this, make sure the camera is connected before launching Skype. If necessary, sign out of Skype and then sign back into Skype. In some cases, it might be necessary to disconnect and reconnect the camera before signing back into Skype.

Slow Logons in XenApp Sites with Read-Only Domain Controllers


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.


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.


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


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.

Field guide to XenApp 6.5 session pre-launch

While preparing for XenApp 6.5 I came across this good explanation by David Gaunt about session pre-launch within XenApp 6.5. David explains the CCU model very good and how it is used with session pre-launch.

“A bit of background

Before we go forward, lets take a few steps back over some familiar technology.

Remember in the old days when you would launch a Presentation Server app with a click of an icon and…wait…wait…logon script fires up…profile loads…wait a moment more…ta-dahh, you’re app is ready? Well we, and a few other clever partners, managed to reduce application launch time by doing clever things with the user profile or just trimming the fat that was the traditional roaming profile. But it was never going to be ‘like-local,’ which is really the end-goal of any virtual desktop solution.

In XenApp 6.5 we’ve cracked this launch delay by using a combination of the latest Windows Receiver and a new feature called Session Pre-Launch. Using this feature will mean than any application will start up immediately, without any delay.”
