I hope you can help me. I recently upgraded a workstation at my office (to a whole new machine) and ran into a pretty serious problem. Friday until 5:00 PM, I could access my mail on 2000 Exchange server.

When I shut the old workstation down and put in the new workstation, I tried to set up an account. When I put the server name in appropriate field and typed my username and hit check names, my username does not come up.

So to troubleshoot, (It also is a SMB server) I try to logon to my file share. (My local credentials are the same as server credientials of user account) When I try to logon to share, I just get the Username/Password screen (Never had gotten that before since credentials are the same)

Again, in troubleshooting mode, I try to log on to my user from another workstation. Still can't authenticate via my user. Every other user can authenticate and load up their shares/mailboxes. I have restored Exchange from the backup as of 3 days ago (Thursday) but the exact same issue is still there.

I really do not understand what is wrong and what else I can do to troubleshoot. If anyone has some pointers for me, I will surely accept them.

Thanks, Mike
