Some of you may have noticed there were some missing tabs in Active Directory Users and Computers after you installed RSAT on Windows Vista.  Specifically the Terminal Services Profile, Remote Control, Environment, and Sessions tabs are not there.  The reason behind this is because Windows Vista is missing the TSUSEREX.DLL...basically it can't be a Terminal Server.

Ned from the Directory Services team has posted an unsupported fix for this on the Directory Services blog.  I snagged the fix here for you to see.

1. You can use your Windows Server 2008 AD Users and Computers snap-in by terminal serving into the remote administration sessions.
2. You can make your RSAT DSA.MSC work the way you’d expect by taking the following unsupported steps:

A. Locate a Win2008 Server which has DSA.MSC installed via Server Manager features/roles. The installed OS platform architecture must match your client (so use 32-bit OS server if using 32-bit OS client, and the same for 64-bit).

B. Locate the following two files:

%systemroot%\system32\tsuserex.dll
%systemroot%\system32\en-us\tsuserex.dll.mui

(NOTE: If not running US English, the path would not be EN-US; it would be the language(s) running on the server)

C. Copy these two files to the Vista machine running RSAT tools and place them in the same paths.

D. Run as an administrator:

regsvr32.exe tsuserex.dll

E. Start DSA.MSC on the Vista machine and look at a user's properties - the tabs will now be there.
