We get the following error ever so often with different users trying to log into their account after a reboot or logoff "The Trust Relationship between this workstation and the primary domain failed."
I have developed a work around for the user where they unplug their network cable and log in using their local copy and then plug it back into the connection.
I also have done the following suggestion found online (This suggestion did not work):
My Computer -> Properties -> Advanced System Settings -> Computer Name -> Network ID… -> This is part of a business network… -> My Company uses a network with a domain -> Next -> Enter your domain username and password -> “An Account for this computer (“COMPUTERNAME”) has been found on the domain “DOMAIN.” Would you like to use this? Yes -> Add the following domain user account (the one you usually logon with) -> Administrator (if that’s how you roll) -> Finish -> Restart.
