Comment:
Is it possible for a Win2003 Server to operate as a DHCP server and connect to the internet with only one NIC? Thanks in advance for the help.

Seems like you are describing a Small Business Server which does dhcp and connects to the internet.
So what was your question?

In a word:
yes.
In general you'd want two NICs for best practice, but you can use just one. Simply set your NIC to have a static IP address (network connections=>lan connection=>properties=>tcp/ip), and then install and configure the DHCP role.

why would you think you can't do it?
Do you understand how to set it up?
you only use two nics if you want to control internet traffic via the server.

There is no need for 2 NIC`s on SBS for DHCP. The amount of NIC`s in the server is entirely irrelavent to how DHCP works unless you wanted to create a superscope and have the said DHCP server serve multiple subnets. In best practice SBS should only ever contain 1 NIC. Multihoming is not supported on a DC and also SBS 2008 only supports 1 NIC with the server behind an existing firewall. Although ISA was included with the premium edition that is a horrible practice. You do not in any network put your DC in the perimeter network and expose it to the internet. ISA is a nice product but its NOT a sensible perimieter firewall purely because it sits on a windows platform. Plus in order to use its functionality all clients must also have the firewall agent deployed to them. In a real scenario its only use is as a proxy.
