Server 2008 RAS Demand Dial VPN

Trying a secure connection between networks, and the interface "Internal" is
configured to get an IP from a range. The first connection works, and the
"Internal" is given an IP, but successive attempts to connect give an
"interace already connected" error, and the IP is still in place even when
the VPN is disconnected. I can't reset this, even tried disabling the
network cards...

I have 12 sites, and 3 of them started doing this.. Running Server 2008 x64
dialing to another 2008 box..

Thanks.

This is the current configuration, and unfortunately, that Internal
connection gets and keeps it's IP before the demand dial connection starts.
