If I understand this correctly, you have a asp.net web application which is
using a webervice proxy to talk to a webservice on another machine. You have
set the webservice to authenticate using Windows auth, and it is SSL
encrypted as well. You mentioned that when you run your app on the same
machine as the webservice, it works. And it fails if run from a different
machine.

Can you provide some details here:

1) You have setup the webservice to impersonate using windows auth. Is it
impersonating the authenticated user who is sending the request ? Or is it
impersonating a specific user on the machine.

2) Can you hit the webservice using IE from another machine ?
