It's because of the Active Directory provider. If you aren't using it, don't need to use it, aren't planning on using it then open up your web.config and comment out all lines that start with <add name="Authentication".... /> under <httpModules>. If you are planning on using it then read this post http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/89/threadid/194161/scope/posts/Default.aspx for information on getting a beta replacement of the provider.

I had the same problem, and this is exactly the thing that fixed it.  It was the first time I ever selected Active Directory authentication on an install, so it had never occurred for me before.  Thanks for hitting the nail on the head and for the link.

That may fix it, if you needn´t the ad provider. But what´s the solution, if you need it?
