Ok. I just migrated off our windows 200 server PDC to 2003. Tested the DNS for about 3 days and all looked ok. So we demoted our 2000 box and raised the domain and forest levels to 2003. No our outgoing mail will not route unless it's dns settings are pointed at the old 2000 box. I left DNS running on it just in case. Is there a way to transfer those DNS settings from the 2000 box over to the 2003 box. We though it worked fine through AD but when 2000 box demoted that was not the case. There are no DNS errors on the 2003 server in the event log.
