Not quite sure what forum to put this in, but this one seemed as good as any !

I want have two isa boxes in different locations, with the locations connected internally via a wan. I would like users at location A to failback to using the ISA box at location B if the internet connection goes down, and vice versa.Using wpad, I can get the browser to check for availability if the ISA is down, but if ISA is up, but the internet connection is down, it browser still connects to the ISA without the internet connection. Using a connection verifier, I can check for internet connectivity, and down the firewall service, thereby re-directing the browser to the ISA at the other site, but once the firewall service is down, the connection verifier etc is unavailable.

Does anyone have an idea on how I can start/stop the ISA box based on internet availability ?
