Heath,

I've seen NDIS drivers in Windows die for all sorts of reasons.
Generally they cause the system to BSOD but I've also seen them start
throwing so many hardware interrupts that the system grinds to a halt.

You should see if you can update your NIC's driver to the the latest
version.  If that doesn't work let us know.  There are some real
Windows networking ninjas on this list that may have a few more ideas.
