Hi Craig,

I don't have a solution for you, but a few other list members have 
indicated that Windows Updates may have caused their VPNs to stop 
working.  I wrote back to at least one of them, but haven't had a 
response.  This leads me to conclude that they found a fix for their 
problem, suggesting that there is one available.

Something that would be very helpful is a list of the Windows Updates 
applied that caused the VPN to stop working.  That would at least give 
us a starting point for debugging the problem.

In the meantime, I'd try re-installing the latest Shrew 2.2.0-rc-2 (from 
the HEAD DEVELOPMENT section of the downloads page) to see if that makes 
a difference.
