RE: WebException - ProtocolError from web service on new server

I started looking at the IIS logs and discovered a difference between the
test server log (which works) and the live sever (which fails).

A successful return from the web service via the WinApp looks like:
cs-method sc-status sc-substatus
POST 401 2
POST 200 0

But the failed attempts look like this:
cs-method sc-status sc-substatus
POST 302 0

I'm still hoping someone can throw out some ideas.
