i have a Vista Business workstation connected to a Windows Enterprise Server 2003. On logging into the domain I regularly get "The trust relationship between the workstation and primary domain failed" then cannot log on. This error does not occur on the XP workstations connected to the same domain. So the error must be in Vista but where.....?Any help would be great

Do you have certificates set up on your domain? Are you properly joined to the domain? What type of domain is it? Need more information please

Everything is set up correctly. All TCP(IP) settings are correct. Certificates are correct. The domain is just a Server 2003 Enterprise domain.The XP workstations attached to the same domain do not have this problem only the Vista workstation. Every day I come back in and the Trust has failed.The permanent fix I have managed is to log onto the Workstation as Administrator but this defeats the object.
