I would look closely at your DSL router. One of the little nasty secrets of dsl routers is that while they support pptp pass-through, they don't say anywhere in their documentaion how many encrypted tunnels they can handle. We recently experienced this problem at a conference were we were using a universities network to establish a sort of WAN back to our offices. We had several machines behind a DSL router to give us some seperation from the UC network. We were just VPN'ing from the individual PC's we were using for registration, inventory, etc back to our ISA 2000. We had a very hard time getting anymore than 3 PC's to connect at a time. I switch to a from a D-link to a Linksys and it worked fine. If you need to keep multiple machines all connected, you may think about placing a isa 2004 box at the far end and let that be your router. That was the direction we were headed, but we simply ran out of time and had to go with the dsl router. Since it was a temporary need, it worked fine. But in the future I think the isa 2004 box would have been more robust.

Can ISA 2000 accept multiple VPN connections from the same IP or same MAC address ? I am trying to pinpoint where my problem is. I have mutiple people VPN'ing into our system without a problem, accept for two machines. I basically have a warehouse where we have two PC's connected to an ADSL router and only one machine will ever connect to the VPN. The other either times-out saying 'the server did not respond in a timely fashion' or just does not find the ISA server at all. Both machines can browse the Internet fine !
