When I try to add a new DFS Domain Root on a Windows 2003 R2 server I get the following error when clicking finish:-
"The following error occured while creating DFS root on server servername.domain.local:
The object identifier does not represent a valid object."
I can add a new Domain Root on another server without any problems. I also tried creating a DFS root on another server, then adding the problem server as a new root target and get the same error".
There is nothing in the event logs to suggest what the issue is, I've checked and there are no existing DFS root's that could be causing an issue (this is the first in the domain).
I've also tried running DFSUtil /clean on the server, but that had no effect either.
