Jean-Pierre Paradis's Blog: RSAT and ADUC for Vista - Update to add tabs for Terminal Services Profile, Environment, Sessions, and Remote Control

Ned here. After much strife, here is the hotfix to get RSAT AD Users and Computers to include tabs for:

• Terminal Services Profile 
• Environment 
• Sessions 
• Remote Control 

960890 Some tabs are not available in the properties of a user account in the Active Directory Users and Computers MMC snap-in after you install Remote Server Administration Tools (RSAT) on a computer that is running Windows Vista
http://support.microsoft.com/default.aspx?scid=kb;EN-US;960890

If you have been hacking away at this previously to make it work, make sure to unregister and remove your server DLL's before installing this update.
