Hi folks,
I’m a little confused — I have two Windows 2003 DNS servers that are on the same subnet. Each has DNS running correctly, and each runs its own separate Forest.
Server A: 192.168.2.5 running domain A.com
Server B: 192.168.2.10 running domain B.com
In order to allow each server to resolve the other’s DNS records, I simply edited the network properties of the NIC on server A and added the IP of server B as the secondary DNS server.
I then did the same thing on server B.
However, pinging the domain or doing a DNS lookup still failed on either server. Perplexed, I then configured a Forwarder on server A for the domain B.com and configured a Forwarder on server B for domain A.com
Once I did that, DNS resolution between servers worked fine.
So what am I missing here? Shouldn’t DNS first check the primary server, and if that lookup fails, check the secondary server? If that’s the case, then I shouldn’t have needed to set up Forwarders on each server.
Please help me understand
Thank you!
