Error:
Citrix offline plug-in Error
An error occurred while starting your application.  Please contact your help desk.

You receive the above error when launching a streamed application.

I experienced the issue after someone changed a username within Active Directory.

You may also receive the below error within the event log

Error:
Launch of application from the location failed and the last error message was: An error occurred while starting your application.  Please contact your help desk.

To resolve, logon to each Citrix server where the streamed app is assigned to and open a command prompt.

Next, type: cd “c:\program files\citrix\streaming client\” and press enter

Type radecache /flushall

Try launching apps again. If this does not work, run the same command on the profiler server and try again.

Citrix Load Evaluator Memory/CPU Utilization at 100%

If you come across one or more of your Citrix Servers Load Evaluator reporting memory/cpu utilization at 100% but there is no one logged onto the server. A possible cause is a patch which was applied to the server. Try the below to  resolve:

1) Copy the following file from a Citrix server which is working %systemroot%\System32\Perfstringbackup.ini to the same location on server experiencing  the issue.
2) Open a command prompt on the server experiencing issues and type lodctr /R:perfstringbackup.ini
3) Reboot the server

The above should resolve the issue. If not follow http://support.microsoft.com/kb/300956 to rebuild the Performance Counter Library.
