Setup 2 W2K3 servers over VPN, how to setup DNS

[scriggs]

I have 2 W2K3 servers which are configured to network to each other.

Server1 192.168.3.100 / 255.255.255.128
Server2 192.168.4.100 / 255.255.255.128

On each server I have set ROUTE so that the servers network OK.

I plan to setup a VPN and connect the computers over the VPN. Each server will have a unique IP on the VPN, how do I integrate this into my DNS settings on the server?

Are the servers both in the same AD domain? Do you have an AD domain? If you don't have one, I'm not implying that you have to have one.

Do you have separate DNS servers for each network?

If each server has its own separately maintained DNS, then you just manually create an entry for the remote server using the local IP that the VPN server is going to assign the remote server. Do this on both sides, and as far as DNS in each area is concerned, the remote servers have local IPs.

If the servers share a common DNS, it's a little more tricky--conceptually, but not on a practical level. You will want to create a pair of A-records in the DNS, one record for the real IP and one for the virtual VPN IP. By default, Windows 2003 DNS uses 'subnet prioritization' when it hands out multiple A-records as the result of a query, and the IP that matches the local subnet will be at the top of the list.

If my solutions don't match your scenario, let us know, and we'll give you something else.
