I was thinking DNS also. A quick and dirty test would be to open a
command prompt on the problem workstation and try "ping domain.name". It
should resolve to the address of one of your DC's and ping. If not,
definitely a DNS issue. If not, have you check running processes on the
problem system? You may have a virus, being that it is a Windows system.
