explorer.exe and Print Management suddenly stops in a Citrix environment

Hi all!

Some weeks ago I hit my head with a easy but annoying error: When a user opens a explorer.exe or Print Management published application in a Citrix environment, the application suddenly stops/disappear with no error message. After a time troubleshooting, it seems to appear a hidden error message: Server execution failed

In spite of we have two different errors: explorer.exe and Print Management, the error is the same because Print Management application runs explorer.exe with a parameter.

Environment:

Citrix 7.5 running Windows Server 2008 R2.

The problem:

The error appears because Windows Explorer looks for "Personal" folder specified in the registry hive:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\

If the folder does not exist, fails.

Resolution:

The problem was detected and solved by Microsoft with the KB2444677

If you cannot apply the KB article(restart needed, or others...) you can do two actions:

1. Change the folder path for an existing
2. Create the specified folder

Hope it helps!
