This is a unique question and I hope I can ask this correctly, we have recently had a client move out of a building and has bought a new server and as requested kept the same domain name but wanted it rebuilt. We have the domain up and running and I have joined all the pc's to the domain by just changing it to workgroup mode under the local admin account and back to the domain with the same username and credentials, however one computer was setup years ago and no one knows the local admin account. So here is the problem
The domain at the old building was mycompany.local, at the new building it is mycompany.local running SBS also. Per clients request we kept the usernames the same so joining the domain for most went without a hitch because it thought it was the same domain with the same username just different password, or we just logged on with the local admin account and disjoined and rejoined. however with this computer, no one knows the local admin account info and the username on this computer has changed from ccornett to acct. When I logged in it asked me for the new password as planned however the computer will no login saying that the computer does not know or trust the domain even though it is the same domain name as before and SBS 2003 as in the previous building.
Is there anyway I can force the computer to login with the new username and password? Is there a way to reset the "trust" it has with the same domain as before? I have not tried safe mode yet to see if the local admin account was never changed but wanted to know some other things I may try.
Oh FYI, I tried to add the old user account to see if it would login and that was a no go also, it would do the usual password change per policy but would never login. Also I tried to add the computer name manually but that has not seemed to solve it either, any help would be appreciated.
