Vista - VPN L2TP error 789 with Vista / Windows 7

Hello folks,
I can't consistently connect over VPN using L2TP, I get error 789.
Others using that server can connect consistently. Here are some
details.

- I'm using Windows 7 but had the same problem with Vista.
- I can connect sometimes, maybe every 10th reboot.
- I've saved copies of system and application event logs and compared
them, there are no differences other than the listed order of items that
all happened to start in the same second.
- I've saved copies of services running and they're the same.
- I've tried a clean boot using msconfig with all non-ms services
stopped and no startup apps running.
- I've tried removing my home router from the equation and using the
modem directly.
- Sometimes it works for a clean boot and sometimes not. Same for a
full boot.
- We're using pre-shared key authentication.

Any ideas? I've been trying to get this nailed for two days and it's
driving me nuts.

Nope, no Cisco VPN client.

Anyone have any ideas how to troubleshoot this? What might be different
on my system the 1 in 10 times that it succeeds? I've looked at system
and application event logs and the same events happen after boot. I've
compared lists of running services and they're the same.

I'm stumped.
