Recently my DB server ran out of space and DB Error LOG file was occupying about 20 GB. When I checked Application Event log of my DB Server and saw an error filling up around 20 times in 1 second.
An exception occurred while enqueueing a message in the target queue. Error: 15404, State: 19. Could not obtain information about Windows NT group/user 'Domain\user', error code 0x5.
An exception occurred while enqueueing a message in the target queue. Error: 15404, State: 19. Could not obtain information about Windows NT group/user 'Domain\user', error code 0x5.
The SQL Server service account and the SQL Server Agent account requires the same account but with DOMAIN ADMIN privileges. In my case the SQL DB service was ran by local administrator. I have changed local administrator to domain user account and restarted the service.
Then SQL comes up without any of these messages in the Event Viewer and DB Error log file stopped generating.
Hope this helps anyone else having the same issue.
