what is in front of the isa server connecting to the other end of the tunnel? a 
router or some such?

Subject: [isalist] PPTP Interface not working

Hello,

I have a site to site VPN based on a PPTP VPN that has stopped working. I have 
received the following error when attempting to start the interface.

An error occurred during the connection of the interface.
The modem (or other connecting device) is already in use or is not configured 
properly.

PPTP clients on my internal network can connect to the target server but the 
Demand Dial Interface on my ISA server returns this error.

I have been using this connection for over a year and it seems to have stopped 
working after I applied the latest patches to my ISA 2006 SP1 Server. That may 
not have anything to do with the problem.

I don’t see any traffic in the ISA Logs.

Can anyone help me out with troubleshooting this problem.

Thanks

Bill
