I have been using SharePoint for a while now as a user and have never really had much trouble with accessing the SharePoint sites I use.  Well I finally ran into a problem with one.  Here is the error I am getting:

 “You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept.  
…
HTTP Error 401.2 - Unauthorized: Access is denied due to server configuration.
Internet Information Services (IIS) ”

It turns out that Windows Authentication doesn’t always work so well with Proxy servers.  The solution to fix this is to use Basic Authentication and have SSL.  I will see if the guys I am working with will get this set up for me. =)
