We have a customer who will soon be moving from an SBS 2003 domain to a 2012 R2 domain with Exchange 2013. I am testing this in a virtual scenario first. I have taken a copy of their SBS2003 server and am now running it in Hyper-V. I have created a second Hyper-V guest with Server 2012 R2
So far, I have joined the 2012 server to the domain as a member server, then I installed Active Directory Domain Services on that server so that the schema would update. DHCP is now running properly from the 2012 Server.
I am stuck at the moment however, because DNS doesn't appear to be replicating.
In the DNS Server event log on the 2012 server, every couple of minutes Event ID 4013 is logged:-
The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.
If I run dcdiag /test:DNS
then I get the results as shown in the attached text file.
I can ping both servers by name from each other, and I can see that my 2012 server is registered in DNS on the SBS2003 server.
The IP (v4) configuration on both servers has the Primary DNS address set to that of the SBS server, and the Secondary DNS address set to that of the 2012 Server.
I have left both servers on overnight, and still no replication. I am at a loss.
