I had a work computer (Windows 7) set up with local login (not domain login). Later I needed to login to the domain.
So I made changes to join the domain by right-clicking on My computer and generating a network Id and entering the domain name there. I was successfully able to join the domain.
Now I cannot log back into the local login. I get the message saying "the trust relationship between this workstation and the primary domain failed".
How do I fix this?
