Split DNS Prob. in MS environment

by elliotross . Updated 25 years, 7 months ago

I am having a DNS problem. Behind the firewall I am using NAT addresses in the 192.x.x.x range. I also have a DNS server behind the firewall for local resources. I also have a DNS server outside the firewall for external resolution.

On the clients, the DNS server that is “first” works OK, the second one does not. I thought that if DNS server #1 could not resolve, the client would then check DNS server #2.

What happens is that DNS server #1 is checked & then will simply fail. (So I can access either internal, or external – not both)

I also tried to set the internal DNS as a secondary of the external primary – that also did not work.

What is required for proper split DNS on NT ?

Thanks.
