You might want to start with a 2003 book. Your issue is that your router is providing dhcp address which include the dns of your isp. Since the workstations use dns to find the server, and the isp dns doesn't know your server and never will, they can't find the server. You need the 2003 server book so you can configure Active Directory and DNS correctly.

Peter, do you realize how difficult it is to read a seven line "sentence" with no punctuation? Posting questions in a lucid and correct manner goes a long way in showing that you're willing to make the effort to help us help you. :) "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Install DHCP if not installed earlier. If installed goto admin tools>dhcp. Just add a new scope for the ip range, add lease and domain name and then you are set to go. You would also need a DNS server..so please install it. you can either install dhcp/dns from add remove windows components or use the configure your wizard to do that. if you are a newbie i would highly recommend you to get a book and study.
