Tracing NTLM (via: 407 Authentication required – no challenge sent – Stack Overflow)

Posted by jpluimers on 2014/08/26

Might need this one day:

I wrote a utility to decode the NTLM blobs that were sent in the IE and HttpWebRequest sessions.When I look at the HttpWebRequest and IE, they both request 56bit and 128bit encryption from the server.

In both IE/HttpWebRequest, they are requesting both 64 & 128bit security. However, for windows 7, 128bit security for NTLM has been made the default, and without that, authentication will fail. As you can see from the server response, the server is only supporting 64bit encryption.
