I Have two domain controllers xxx.xxx.xxx.1, xxx.xxx.xxx.2 and a gateway router xxx.xxx.xxx.3

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you mean DNS it should be 1 and 2 and 2 and 1. Domain Controllers only really need to point to themselves but it doesn't hut to point to the other domain controller.

What about network users computers? Should they have 1 & 2 for DNS or 1 & 3 so they can pick up internet DNS? How does a workstation translate google.com into 74.125.196.102

1 & 2. Set up the DNS server properties and set the forwarders to your ISP's DNS servers. So when they use the DNS server they can resolve local domain resources and for anything on the internet your DNS server will forward the request to your ISP DNS servers.

Just a note by default your DNS servers will find some root DNS server to forward to if you do not specify a forwarder. So you don't HAVE to put your ISP DNS just recommended.

OK. in Server 2012 I  would use DNS manager | Myserver | properties | Forwarders | Edit | Then add my ISP DNS servers, yes?
