best practices question on domain setup

I am about to set up a 2003 server for the first time. I'm not to familiar with Active Directory. I'm looking for some basic advice on best practices/setup. I have had experience with the NT4 server and domain environment. This server will only have about 5 users and is purchased for the sole purpose of running an accounting application. One of my concerns is the naming of the domain. The company already has a website and this server will never host it, so I believe I will just create a domain name that has nothing to do with their registered fqdn.

"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.

The domain name should be a two part name, the normal recommendation is to use something like mydomian.local or mydomain.lan
