I don't immediately see how it's possible to tell if a PC is able to authenticate without asking it via a 401, which produces a browser auth pop-up. Is there anything in the initial HTTP request that you can use to tell this class of clients from the other class of clients?
Well, perhaps you could use Group-Policy IEM tool to modify the User-Agent and show the 401 to only those guys via some simple VPE logic? But they would have to use only IE, unless there is some way to do this with Firefox to a group of PCs.

Hi Lucas,
thanks for your response. I already thought about changing the User-Agent so that I can check for this header.
For the moment, I could live with the 401 prompt, when I can display the auth form after canceling the 401 prompt. But no matter what I do, I receive "Authentication required to access the resources.", when Negotiate is enabled in the 401 agent.
