Well, we had two former DCs. They were both rather old (Dell PE-2550), and they were upgraded from Windows 2000 to Windows 2003. All had been fine, until...
We demoted them to member servers. The DNS broke on both of them. No (other) machine with one of these machines listed first in its DNS stack could resolve anything. So, we had to go in and change all our machines with static IPs to point to machines which were still DCs. -- Richard D. McClary Systems Administrator, Information Technology Group ASPCA® 1717 S.
