Not exactly neighbours but less than ten minutes apart by car

tnx Dalight for the info and encouraging reply

Haha! I had to do a double take as I didn't remember posting a reply. Anyway, good link Bishop, very informative.

If you have AD do you need DNS Server

Yes. Whereas WINS was Microsoft's proprietary name resolution service for NT based domains, Active Directory is built around DNS and just about relies on it. You'd have a hard time implementing AD without DNS. That said though, I bet you could do it with open-source DNS but why bother since MS provide integrated DNS services?
