Um . . . I'm not an authentication expert, but this sounds like it might be
that NTLM doesn't do double-hop auth. If it's you own in-house app, the
solution is to use kerberos and delegation. I don't know what
kb/whitepapers cover this, but there ought to be good enough search terms in
those previous 2 sentences for you to find a good explanation with your
favorite search engine.

If that's not it, I'd start sniffing the network traffic.

(btw: The path you asked about in your first post looks like it was from the
group policy snapin in mmc.)
