I have a problem with 1 of the computer in the network.
This user recieved in the previous logon a message to change his password because it has expired , but he didn't change it. Then, when he tried to logon into the computer the later he recieved a msg that "The system couldn't log you on, either the domain name or user name is incorrect.
I have reseted the user password but this didn't solve the problem.
Then, i loged in as an administrator and i tried to add another user in the network to this computer but i recieved an error"The trust relationship between this workstation and the primary domain failed."
