title: "No credentials are available in the security package" when running SP Foundation 2010
body: <p>I am having an same issue when trying to run SharePoint Foundation 2010, and I am using the NTLM Windows Authentication Provider. We are running IIS 7.5, and we have a dev SharePoint site set up on another server, using the exact same authentication, but for some reason, the site on our prod server throws the error "No credentials are available in the security package." This fails using all browsers, and it fails when I run the site from the server directly as well as from any client machine. We have Windows Server 2008 R2 Standard on both machines. </p>
  
  <p>I've checked that all the security settings for the SharePoint app pool as well as the SharePoint Web Services pool matches our dev server's settings, and they all do. </p>
  
  <p>Any ideas? Thanks.</p>
