Today I’ve spent almost the whole day to figure out why an application (COM+) couldn’t authenticate against a ASMX web service. Using my favorite networking tools Wireshark and HTTP Fiddler I saw that the credentials didn’t get included in the initial request, and no other request was made when the 401 challenge came from the web service.
