I am an IT volunteer for a charity organization. We have a windows 2000 server and 8 XP Pro workstations, recently the workstations were upgraded to Windows Vista Business. A workstation was renamed. The next day the user was not able to log on the machine, the message appeared: “The security database on the server does not have a computer account for this workstation trust relationship”, I’ve managed resolve the issue by restarting the Server and the workstation. However, the following day, the user had same problem, so I restarted the server again and it worked. How do I solve this issue permanently.
