Symptoms

Users receive an error 'HTTP 500 Internal Server Error' while trying to
browse to a SharePoint site using Claims-based authentication. We see the
following error message under the event viewer on the SharePoint server

</EventData>
</Event>

We also noted that if we direct the
requests to another server in the farm, we are able to access the
site.

Cause

Application pool account was missing the "Impersonate a client after authentication" user right

Resolution

1. Go to Start - Administrative tools - Local Security
Policy - Local Policies - User Right Assignments - Impersonate a client after
authentication properties
2. Add the Application Pool account for the site
which is not working
3. Reboot the server, so the changes can take effect
4. Browse the site and it should work fine

I had this problem. After 'Cookies' cleaning, the site was working with no problem.
