After demoting my one and only win 2k DC to a member I ran dcpromo on a new 2k server. I joined all of my 2k and xp clients to this new domain with no problem. But when I try to join my old DC to this domain I get an error. I checked the event log and I am getting DNS errors. DNS was running on the old DC and I removed it after I demoted it. DNS is now config on the new DC. All ips are static and and tcp/ip config points to the new server. I confirmed this by running ipconfig on the old
DC. Ping works from old DC to new. Two questions, How can I fix this and how should I have done it in the first place? Thanks.
