After upgrading our Citrix Presentation Server 4.0 environment to Presentation Server 4.5, Citrix users are no longer able to modify the desktop wallpaper or display settings. The display properties are greyed out.
Each anonymous user has Power User and Remote Desktop User permissions.
I have checked the terminal server configuration properties on the Citrix servers and settings are set correctly. I have ensured that active desktop settings are not configured in Group Policy.
We are running the Citrix on Windows 2003 R2 Enterprise Server SP2.
