I am running Windows Server 2003 with Windows 7 clients. All of the users are setup as restricted users. A while back, I had to do a system restore to one of the client machines. Upon doing the system restore, I unjoined and rejoined the client PC to the domain to prevent any trust relationship problems. The user has had no problems to date logging into her PC.
Today, she asked me to install some additional fonts on her PC for a project she is working on. When copying over the fonts, I was prompted to enter an Administrators user credentials. I typed in my username and password and received a Trust Relationship Failed with the Workstation error message and my credentials were not accepted.
At this point, I cannot even go into the System Properties of the PC to unjoin and rejoin the domain because it will not accept my admin credentials. Also, if I unplug the network cable then I receive an error stating that no server is available to authenticate my username / password.
What I find strange is that the user can log in and out of the PC with her credentials without any problems with or without the network cable being plugged in.
