The above portions of the Robot configuration and the console output you
sent earlier look correct to me. You will not get a connection on the
server side until the proxy authenticates the Polygraph robot. 

Since it is the proxy doing authentication with your AD, I would
recommend looking in the proxy logs for more clues. For Squid support,
see www.squid-cache.org; there may even be an FAQ entry for NTLM
authentication there.

If Squid logs convince you that Polygraph is at fault, please send your
Polygraph workload, Squid configuration file, and a few packets captured
on the client side to bugs-mN9fGWdlm5pku/f+YMZH/[email protected]

Good luck,

Alex.
