title: AppFabric 1.1 Caching (crashing windows service)
body: <p>I have a test installation of AppFabric 1.1 x64 (Hosting + Cache) on a single machine (domain-registered, Windows 7 Enterprise). Installation and configuration went flawlessly (cluster with just 1 machine, configuration stored in SQL), I'm running everything locally (including SQL Server 2008 R2). Problem occurs when I want to start "AppFabric Caching Service" - it crashes after few seconds and following entries appear in Administrative Events (in Event Viewer):</p>

  <p>Do you have any clue what may be wrong? I've seen <em>"Invalid URI: The hostname could not be parsed."</em> message, but name in configuration seems to be perfectly ok (even if it looks odd, it's a proper name of my computer). Any help would be appreciated.</p>
  
  <p>P.S. I had AppFabric 1.0 before and it seemed to work fine. I've uninstalled it before installing AppFabric 1.1.</p>
