John,

I believe this is a delegation issue. If you are accessing your machine
locally using windows authentication on the IIS application then your
machine has your username in a format that it can pass onto the other
server. If you try to log on from a third machine onto your machine then
all the web server has(you machine is your login/password in hashed format,
which can't be passed onto a third server in a format that is acceptable).

Try switching your IIS application security to basic, and see if it works
then. If it does, then I bet that is the problem.

You can either set up delegation, or use basic authentication on your IIS
app. by using basic, then your login/password is sent plain text to the
webserver and is still in a form that can be hashed for authentication by
the 3rd machine.

A good solution is to user Basic authenitication on the IIS application with
httpsso the plain text transmissions are encrpyted...if you want more
security on that part.

I think this is the problem, but please let me know if not.
