XP Pro -----> Win 2003 Server. I can join the domain as a domain user, no problem. I can log on locally to the machine as Admin, no problem. I can log on to the machine as a Domain Admin, no problem.

When trying to add a domain user to the local Admin Group, I get an error message saying the domain doesn't exist or could not be contacted.
I have other machines on the domain that have local admin rights so I dont think it's a server issue.

Any Ideas????
