Go to Add/Remove Programs and install DNS service. Then go to Computer Management and go to the DNS console and create a zone for your domain.com (or .net or whatever) then inside the zone create an A entry for domain.com to forward to your IP and 2 NS entries for domain.com to go to ns1 and ns2.domain . Then go to Godaddy domain management. Scroll all the way down in your domain screen and you can add NS entries there. Add ns1 and ns2 for your domain for the IP addresses of your server. This might all sound confusing but search on google for IIS DNS and you'll get some nice tutorials.
