VPN broadband vs. dial-up

I have set up a VPN at work using RRAS. So far it works fine with the following exception:

When I dial up (Bellsouth ISP) and establish a connection to the VPN everything works the way it should ... ie. if I go to start->run and type \\servername ... I go to the correct server. If I ping "servername" it resolves to the internal networks IP address. If I drop the VPN connection and ping the "servername" it resolves to the EXTERNAL ip address.

So far so good ...

When I use a broadband connection (Cable or DSL always on NOT PPPoE) and establish a VPN connection it doesn't work the same way. If I go to start->run and type \\servername I get nothing. If I ping "servername" I get nothing. If I ping the FQDN ("servername.company.com") I get the EXTERNAL address whether I have the VPN connected or not.

This is with the same client machine by the way.

I don't think it's really a DNS issue, but rather how M$'s VPN software interprets how the initial ISP connection is established. M$ VPN seems to be tied to the whole "dial-up" concept. I'm assuming it tries the VPN connection first and if the address does not resolve it goes out the internet connection. But there is no real dial-up setting for a broadband connection.

Anybody have any advice? Other than switching to Funk or some other VPN server/client software. I don't have a choice in the matter ... we either use Microsoft or nothing. I am pushing for the VPN in the first place so we can drop FTP and (reverse) Proxy and other things.
