So I have a win2k server with win2k clients. One client (on the network 4 or 5 months already) "suddenly" stopped being able to logon sometime in the past couple days. The worker came in on Sunday, reportedly to a functioning computer. He was out of the office M + T, now when he tries to log on he gets a "Local Policy on this system does not allow you to logon interactively" error. This is just on one machine. The machine won't let other user accounts or the domain admin account log on either, and gives the same error when you try to log on locally to the machine. All accounts work from other client computers, including the user in question. The cable connection is fine, and other clients are working fine. Any ideas?
