Question:

Using Remote Server Admin Tools (RSAT) on Windows 7, the Dial-in tab is missing from ADUC (active directory users and computers). Any suggestions? I recall this was also missing from ADUC on Wndows Vista and Windows Server 2008.

Poking around the internet I see some articles about .dll files to add, but is this the fix?

Solution:

There is no “fix” unfortunately as Microsoft do not consider it to be broken – it seems that the tab was excluded intentionally.

There is a script in this thread that might be of assistance:  http://social.technet.microsoft.com/Forums/en-US/w7itprogeneral/thread/7e7b1220-375c-49c2-8deb-6f8c035ef54c
