I have a little test lab set up for learning Server 2003 (and 2008 later on). What I want to do is create a domain within my existing (school) domain. I’ve experimented with using 2003 as a NAT router and having hosts behind it browsing the Internet, pinging each other, etc., but now I’d like to get more into DHCP, DNS, and Active Directory.
I have a D-Link wired router that I can use for NAT and I’ve even used an OpenBSD appliance for NAT.
What I’d like to know is if I can use a single multi-homed Server 2003 box for NAT, DHCP, DNS, and Active Directory or should NAT be separate from DNS?
