DNS Setup
I have one DNS (DC) setup in a small network.
Is it a common practice to put the internal server (ie. my DC) and a public DNS (eg. 8.8.8.8) for DNS setting ?
Client use public DNS that can't resolove the internal servers will then use the other DNS server (ie. DC) to resolve. Am I correct ?
Thx

One other thing...
If you are using the same domain internally as you do externally (as we normally implement), make sure you have an A record in your internal DNS zone for each public record that exists, and put the public IP there. This will ensure your users can resolve your public addresses.

The Spiceworks thread doesn't really add anything new. Seriously... just point everything to your internal DNS server (including itself) and let it do the rest. You don't need to configure forwarders or anything else. Windows Servers automagically forward unresolved request to root servers, so just make sure your firewall allows it.
(I mention the firewall because on some older Cisco ASA and the old PIX firewalls, there were problems due to Microsoft DNS packet size.)
