I have a question about sites and subnetting under a single domain (windows 2003/windows 2000). I am going to be bringing up a new DC on an existing network at a different physical location. The two locations will be connected through a Sonicwall VPN (already up and working). The existing location has two DCs and around 20 clients. The new location will eventually have two DCs and around 10 clients. The existing location is on the 192.168.0.x subnet, and the new location will be on the 192.168.1.x subnet. What are the steps neccessary to get the new site up and working properly? I think I would like it all on the same domain, and have each location handle it's own DHCP, DNS, and Logon. How do I make sure the clients at the new location use the new DC and not the existing one? Will the two sites show up separately in My Network Places? Can I configure it so they do? Will all of the clients be able to use DCs on either end of the tunnel if for some reason there is no available DC at their location? Do I need to use Sites-and-Services to set this up, or is it done by bringing up the first DC in the new location with an IP address on the new subnet? Sorry, I know there are a lot of detail questions and a very broad original question, so I will make the points high for this. Thanks.
