This is weird. Squid responds as if the client had absolutely no proxy 
authentication header sent. I.e., it doesn't even respond with the 
challenge to the NTLM auth header although it lists NTLM as 
authentication scheme. Are you certain that NTLM is set up properly? If 
you are, can you check the squid log files to see if they say anything 
"interesting" (i.e., perhaps there's something wrong about the request 
but I don't see what that would be.
