I have an environment with Windows 2003 SBS and a few other member servers. one of the member servers is acting as a file server. One particular user can log on to his computer using a domain account but cannot access any domain resources that are hosted on the SBS box without re-entering the same credentials. When he opens outlook he is faced with a logon prompt, which accepts his credentials, when he access shares on the SBS server same thing, Printer no go also. But any resources on the member servers is fine. I had another user log on to the same machine to rule out a computer account issue and he is able to access everything ok. Any ideas?
