RAS DNS Problem

[Joe Sorenson]

I am using Windows 2003 Server on two Computers. One computer is a DC
the other is a Member Server. On the Member Server I have enabled RAS.
I have two DNS zones on the DC: testdomain.local and realdomain.com

When I VPN into the Member Server I can resolve all of the computers
with no problem. However, when I use computer.realdomain.com it
always resolves the Public IP address, not the Private IP address.

How do I force the private IP address to be resolved rather than the
public?

Thanks for the reply! From what I can tell, the DNS lookups are not
defaulting to the VPN DNS server, rather, they are using my DNS server?
I guess I can add 192.168.0.2 to my DNS servers, but this delays
everything when I am not using the VPN.
