Right, but has the VPN software *ever* been installed on your Windows 
machine at work?

Can you try another Windows machine at work and see if it gets the same 
problem?  Such a test would help to uncover anything specific to your 
general computer configuration at work (such as some sort of software 
installed on all of them, etc.).

As for help --- They would at least want you to be running debug 
versions of some Cygwin components.  Ideally you would do some tracking 
down to try to figure out an exact sequence of events that reproduces 
the problem in a short amount of time.
