I installed a Win2k8 domain controller (let’s call it DC1) successfully in my lab situation.
I then installed a new server (lets call it DC2) and then promoted it as a second domain controller.
This went well, the AD user accounts from DC1 were replicated to DC2.
A problem developed after I rebooted DC1. The boot process takes hangs for 5-10 minutes with the message “Applying computer settings” displayed.
The Active Directory Domain Services log has the following entry:
“Active Directory Domain Services could not use DNS to resolve the IP address of the source domain controller listed below. . . .”
There are other log entries in the system indicating that replication has failed.
Forcing replication also fails.
DC1 and DC2 are connected on the same network and are members of the same domain.
Are there additional steps such as DNS forwarding, zone transfers etc required to get replication to work?
Is there an authorization problem?
Initially, I had the following IPv4 Networking details:
DC1
DNS : pointing to itself
DC2
DNS : pointing to DC1
I have now tried criss-crossing DNS addresses so that:
DC1’s primary DNS address points to DC2
DC2’s primary DNS address points to DC1
Using nslookup I can resolve names and IP addresses correctly, but the issue of replication exists.
Thanks in advance.
