I've got a website setup in my virtual webserver using server2003 and can access it from my internal network no probs which includes a domain controller server with dns and active directory and so forth. How would i go about setting it up the virtual machines so i could access the site using my host browser not just by ip but by using the www. name i've got set up for it on the dns server.

Thanks

If you have a (Properly configured) DNS server just set it up and point the guests to use that for their DNS.
If you don't want to use a DNS server you can put the information in your guests hosts file <IP-Address> <Friendly Name>
Example: 192.168.0.10 "www.mywebserver.com" (Without the "")

SteveThePirate87, since you've got A/D on your internal network and I assume that you've got the A/D DNS enabled then if your VM W2K3 is a domain member then it should be accessible as you suggest. I am assuming that you are using a bridged network.
This isn't a VB issue but a straight A/D / DNS configuration issue and if you need help on this then the best place to get this is on an appropriate MS support forum.
