I was forced to rebuild my SBS 2003 server when it got corrupted by virus protection. After formatting the disk and reloading the O/S and installing all the updates, I tried to login from one of the client machines. I get an error " The security database on the server does not have a computer account for this workstation trust relationship. " and it won't let me log in. I tried the Administrator login and password and it still won't let me. So, I'm locked out of my client PCs.
