title: IIS 7 is not responding
body: <p>IIS7 based web site was working a day ago, now nothing.
  The browser just says "waiting for www.sitename.com". I am running the browser on the server with admin rights. No error messages, no log entries, Firefox just waits indefinitely (same with IE). Where do I start? I am clueless.</p>
  
  <p>Thank you.</p>
