Small 3 workstation network behind a linksys router, in a office building with t-1. The network doesn't interact with the other workstations or pc in the building, only internet access. One of the workstations was running slow today after being on over the weekend, rebooted and now the workstation wont log on, it says"unable to log user on the computer, domain (ex) is unavailable. The workstation never required a password before and was never set and isn't on a domain. The proposed domain name is the workstation name. Please help XP Pro w/SP1..
