    I am trying to show to a customer that his IIS server is vulnerable 
    to unicode exploits.  However, access to his server is password protected
    (Require valid-user) I get "HTTP/1.1 401 Access Denied" and 
    "You are not authorized to view this page".
    
    As far as I am concerned, having password box does mean he does
    not have to patch his web server. How can I show that his box
    is vulnerable? Anybody?
