Please remember to mark the replies as answers if they help.If the object that is affected in the collision is a computer or a domain controller, only the RDN that is used to locate the object in Active Directory is changed after the collision. Because the FRS or DFS Replication member object is not updated with the domain controller name automatically during the domain controller rename, we recommend that you rename your server before you promote it to domain controller status. This object must be updated with the new domain controller name so that the domain controllerĬan replicate SYSVOL.

Also, the application server didn't fail over to its secondary DNS because it detects that the primary DNS server The DC is not finish yet in the replication (somehow the dns database is not yet complete), the application server cannot resolve any queries. It seems that it detects that the DNS server in the DC is already active. In the middle of the replication, some application servers seems to be throwing dns query to the new DC. We hadĪn issue before when we demote the old 2008 r2 dc and promote 2012 r2. Also, we are not sure if there are LDAP connection that is using the DC's host name. There are application server that is using our DC's as DNS Most of it are pointing to IP address and some are pointing to the Host name of the DC.
