I have just set up a small server for testing, using SBS 2003. I have set it up as a domain controller, and my dev machine belongs to that domain. One of the first things I wish to test is a scenario where HTTP requests under many domain names access sub-directories of a single parent site.

Both my dev machine and domain controller are both currently set up to use my ISP's DNS, but I think I will need to set the DC up to use the ISP one, and my dev machine to use a DNS on my DC server. Is this a good option? How do I make my dev machine think it is actually accessing 'external' domain names?
