Best setup-single server and 6 users.

I have a new server and 6 client workstations to setup in a small office. What is the best AD solution to use for such a small setup if any. The website and email for this organization is currently hosted offsite. What about wins and DNS, I heard DNS is a must in 2000. If this was NT4 it would be a no brainer. Any Ideas? Thanks in advance…
