Server 2003 install
ISP --> Router's outside Live IP --->Router's Inside local IP (172.16.1.1)

Server 2003 has been assigned 172.16.1.21  with the 172.16.1.1 listed as the Gateway and the DNS server

I can get out and run updates etc, just fine...but my question is on the DNS forwarders....should they be pointing to that router at 172.16.1.1 for resolution....or to my ISP's DNS servers?

It all happends so fast it's negligable I believe, but there have been a times when I did notice an improvement when going straight to the ISP.

Is it a matter of preference ? What is best practice.....to have your in house DC's act as the DNS server for all..with their forwarders pointed to the ISP's DNS servers...or do you want your DC's to point to the router and have it foward the requests?

I configure my forwarders to OPENDNS.com servers.  Gives me extra controll and I get faster DNS than through my ISP's.   I don't see how just pointing them to your router would help because it's just one more devices that has to check its settings and forward again.
dpait,  i use vlan that has multiple ip's  10.0.1.0 - 10.0.50.0 255.255.255.0   must connect to the vlan router and to reduse bandwith to each other..  
dont like the idea of using the isp as a gateway..  not much control on that side if it goes down...

pstrawser, I understand that logic.  But where are your routers pointing?  Same issue there.  It has to get to either the DNS root servers by it's list or get it elsewhere.  I use OPENDNS because they seem to be more responsive than setting my servers to direct to the root servers, although I do have them configured to be userd if I can't get to OPENDNS.

I've setup DHCP to dish out my internal server as the DNS Pri and Sec. and then set my server's forwarders to look at my ISP's DNS entries... everything is working just fine.
