_msdcs DNS records for a demoted DC
Posted on 2011-03-04
We are upgrading our active Directory from 2003 SP2 to 2008 R2, we've decided to demote a domain controller that was also the secondary DNS server, demotion went fine with no errors, but we started having events 1083 and 1955 (Replication conflict) repeatedly, while trouble shooting the problem, we've noticed that in the DNS zone, under _msdcs we still have all the entries for the demoted domain controller, aren't these records supposed to be removed in the demotion process? Should we go ahead and delete them manually? Should we expect any problems in the upgrade process because of these entries?
