I recently replaced the PDC in a 2 server network. I did this by replicating the AD from the old server to a temporary server and then in turn replicating this to the new server. Once I put the new server in place the 2nd server in the group (Engineerserv) lost the ability to replicate AD from it (the new server). I have narrowed the problem down to DNS. When I open the NTDS Settings properties under AD Sites and Services on the Engineerserv the DNS Alias is showing the wrong GUID. How can I change or replace this incorrect information?
