I had the opportunity to test a 2003 VM by now (had to find the install
disk first) and it's working there as well. So while not officially
supported it works.

I had other VPN clients but uninstalled them. Can't spot a driver or stuff
that's left over from any of them, even checked registry.

Sadly Fritzbox doesn't provide that useful logging. There's nothing at all
in there for the unsuccesful connections, for the successful ones there's
"connected" and "disconnected: timeout".
