I have a crazy problem, primarily with Win2k server, but I'm trying to find a workaround. My problem is that i have a ghost user. I have a user who everything was working fine. One day she couldn't access her exchange mailbox. I try working on the machine, then try to readd her to the local admin group. There are two users, the one that should be there and another with the username and the serial number following it. Adding both will not let me gain amdin privs. The second user does not show up on Active Directory users and computers anywhere. I have checked the lost and found, but nothing. anyway If you have fix for the above, that would be great, but how about a workaround. Is there anyway to create a new user, make that user have the same e-mail address as the old user, but different logon. Can I then reassociate the old users mailbox to the new user. Confusing but I'm reaching here. Thank You
