I have 4 laptops running Windows 7 inside this domain. Two of the laptops are having a problem logging in every morning. When these two users try to log in they get an error messege stating that "This workstation has lost the trust relationship between the machine and the domain." When I have the users walk with the laptops to a certian part of the office to log into the domain they can get in and start working normally. These laptops are all on wireless, when they sit back down with the laptop at they're desks, they have no problems getting out to the wireless. How can I stop them from losing this trust relationship between the workstation and the domain? What is causing this problem?
