What is the best way to configure our intranet DNS to work efficiently with our internet DNS? We have our internet dns protected by our firewall with a valid IP address, then our intranet(using NAT) dns is being referenced in our internet DNS by a point of origin in the DNS table. As of right now our intranet resolves internet & intranet queries just fine, but I'm getting some errors in the event log that says something like: oversized DNS errors 229. I imagine that it has to do something with the configuration that's in place. I have enabled forwarders in the root dc (intranet DNS) to point to my internet DNS.  Should we take away that point of origin in our internet DNS table & have them as 2 separate DNS, & just leave the forwarders in place?  Any help.

-I suggest you leave the forwarders in place, or replace the forwarder IP's with your ISP's DNS server IP's.

They should be totally seperate DNS servers, both being master neither being slave and the private server using the public as forwarder.

Thanks Housenet. We are removing that point of origin in the outside DNS table.
