Since Thursday, March 16, we have received some reports of Windows authentication errors, usually experienced during login to Windows after a fresh reboot or at the lock screen. A common error indicated “The trust relationship between this workstation and the primary domain failed.” Temporarily disabling the network, when possible, allowed one to login as normal (using cached credentials).

We found some Active Directory replication issues that may be at fault, and are working to rebuild one of our domain controllers. If you encountered the above error after 3pm today, March 21, please feel free to notify help@eecs with any specifics.

UPDATE

With the troubled Domain Controller being handled, we had no further reports of this issue. All Windows Domain Controllers are now replicating properly.
