WinPE 2.0 connection to web service WhoFan <google[ at ]sueannanderic.com> 5/31/2007 2:05:32 PM I am developing an application that has to run under WinPE 2.0. The application communicates to a web service that needs NTLM authentication. I am using the XMLHTTP control in a C++ application to handle the communication. Under WinPE 1.x this works fine and authentication is negotiated - the world is good. Under WinPE 2.0, I get an exception from XMLHTTP on the send call. Looking at the network traffic, WinPE is sending the request, the web service is responding with 401, negotiate. Under PE 1.x, PE sends the request, web service sends a 401, PE sends NTLM, web service sends a 401, PE sends more NTLM data, web service says 200 - here's the data. I have gone so far as to run FireFox under PE just to very communication and it works fine. So, my assumption is that the default settings of PE 2.0 has a high level of internet security on that XMLHTTP is honoring but FireFox is ignoring. Does anyone know how to change the internet security settings of WinPE 2.0 so I can get this to work? I have looked at the registry settings but do not understand which settings I need to change to make this run correctly.

If you take the DLL from a vista install and put in on the PE system, everything works as expected.
