Http NTLM Not Working

I am having issues using NTLM authentication to make a POST request to an internal website running on IIS.


Looking in the IIS logs I can see that Boomi only creates a single request where it tries to connect using Anonymous authentication and then receives a 401.2 error. This matches the NTLM protocol, but it is at that point that Boomi fails.

It never actually sends a 2nd request with the NTLM credentials.

The above is a section of my IIS logs and here we can see that when I execute the POST request from SoapUI (rows 1 and 2) it follows the NTLM protocol and tries to use anonymous authentication which results in a 401.2 and then it sends in the NTLM domain\user and receives a 200. Then when Boomi makes the same request it stops after getting the initial 401.2
