I have taken a group of PC's and disjoined them from their original domain and joined them to a new domain/new forest. While in the original domain the PC's received printer assignments through GPO. In the new domain the printer assignments are being made manually. The problem is that now after each user logs in (using user names that didn't exist in the old domain) printers from the old domain are appearing 30-60 seconds after login. The domain controllers for the old server have been shut down and the print queues are no longer active. Any attempt to access the old printers results in a long delay with an eventual timeout. I have repeatedly deleted the old printers, but they return at the next login. Presumably the PC's are getting printers through the old GPO configuration -- but how can that be after disjoining the old domain and shutting down the old Domain Controllers?
