I'm back at an institute I was visiting last year. Last year I was using a Windows 7 machine, and both VPN services that I use worked perfectly. This year I am back, but with a Windows 8 machine. Neither VPN service works. Moreover, I have ruled out the problem being with the Institute's network, because my wife brought her Windows 7 machine back with her, and it still works perfectly. The problem is subtle: On a side-trip to Berlin, VPN under Windows 8 worked fine from the hotel's network.
Here are the two errors I'm getting, each with a different VPN server:
1. Standard Windows 7 VPN server, on my own desktop back home: "Error 806: The VPN connection between your computer and the VPN server could not be completed..." It goes on to say that the most common problem is that something isn't configured to allow Generic Routing Encapsulation (GRE) protocol packets.
2. University's VPN server: "Error 800: The remote connection was not made because the attempted VPN tunnels failed...."
Suggestions? T
