I would like to note that these two machines the windows client is
connecting to are sitting on the exact same switch connected to the same
provider handling identical user loads.

There is a possibility that we are hitting an upper level bandwidth
limit between us an our upstream provider due to a misconfiguration on
the other end, but this should only happen during peak time (which it is
not right now). It just bugs me that 2.2.16 doesn't appear to have this
problem.
