I Current have a small windows 2008 AD Domain, as well as 2 completely different forests and subnets. Each with its own unique domain running windows 2003 domains.
All subnets are properly routed via VPN tunnels, and I can ping the IP of the various domain controllers and DNS Servers properly.
When adding the allows Zone Transfer server IPs on the primary zone of the 2003 DNS servers, it worked properly and transferred to the secondary zones of both the 2008 domain as well as the other 2003 domain.
The problem occurs when I try to add the allowed Zone Transfer server IPs on the 2008 dns server. It resolves the hostname correctly, but gives a warning saying "This Server IP is not Authoritative for the required zone"
I have tried some googling, but can not seem to find an acceptable answer.
Any help is greatly appreciated!
