We had a power outtage at one of our three campuses. After the power came on, we started seeing users not able to log in. The Macbooks, couldn't log in with the login window shaking as though it was a bad password. The Macbook users for the most part, are able to log in if they reboot their Macbook.  There are not as many Windows PC users on this domain, but they get an actual error message        " The trust relationship failed...." I have redacted the domain name and ip addresses to post this.  Outside the power outtage, there hasn't been anything changed to have caused this.

Please note, the domain and ip address information was changed in the log below. The rest of the information is directly from a log entry.

You could go to the affected computer properties, click on change domain membership and re-enter the the domain name (i.e. if domain name is xyz.local then enter xyz and if domain shows xyz then enter xyz.local) and this will reset the trust relationship.  Your other option would be to remove PC from domain (i.e. join it to a workgroup) and then rejoin the domain.

Don't know what happened but this should fix it.
