Description

I'm trying to request a page from IIS (6 and 7.5). If the IIS is configured with providers for "negotiate" and "ntlm" then the Negotiate authentication is tried and fails, but it does not then try to use the NTLM authentication which is what I require. If I removed "negotiate" as a provider from IIS and just use NTLM then all works well - but this is not a solution as I don't have control of the web servers.

Output below...
