Lose connectivity after activating vpn client

Am I overlooking something obvious?  I am at my office lan behind a nat router with normal internet connectivity.  I just set up a server at home with rras vpn host.  I can connect to home with the windows 2000 vpn client just fine.

When I VPN in to my server with the built-in windows client from my office I lose the normal public internet connectivity I have at through my office isp connection.  For example, opening nslookup from a command prompt times out finding dns servers.

More generally, with two ip connections active (nic and vpn client) what determines which one an application that tries to connect to an ip port gets?

The routing tables do that. When you connected the vpn connectoid did you check use the remote gateway?

Bingo!  You win the kewpie doll.  I didn't check "use the remote gateway" but it was checked anyway.  Removing the check solved the problem, thanks.

Hmmm.  How is the routing determined on a two-nic multihomed machine running windows 2000, just out of curiosity?

It depends on the tcp/ip settings and routing tables. Normally with a multihomed machine each card is set for a different subnet.

So which gateway is used for addresses outside of both subnets?  Man, I'm learning a lot today!

Here check out this link it might explain it better http://support.microsoft.com/default.aspx?scid=kb;en-us;140859

Normally if you want to route out of both to the same area (i.e. like the public internet) you will need some kind of way to bind the nics or actually load balance them so that they use a round robin approach. First this one then the other one etc.
