title: 404 error when running Crystal Report - when it used to work fine
body: <p>We have an issue that has popped up revolving around running Crystal Reports Via an asp.net web page.</p>
  
  <p>The system was working fine for years and then due to a hard-drive crash, had to be rebuilt.</p>
  
  <p>We copied all files from a 1 day old backup onto the new system with:
  Same operating system - Server 2008 R2
  Same IIS - 7
  Same ASP programs.
  Same Crystal Reports Version 2005.
  Same Web.Config
  Same permissions.
  Same everything!</p>
  
  <p>All webpages work, 
  All database functions work, 
  But now, we get ...</p>
  
  <p>"HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed"</p>
  
  <p>... error when trying to run the pages that load a Crystal Reports report.</p>
  
  <p>All asp files are there. (as well as all other files from the backup)</p>
  
  <p>Only the CR reports die.</p>
  
  <p>When turning off custom errors, the only thing it says is:</p>
  
  <p>"HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed"</p>
  
  <p>When turning on log files, all we see is "xReport.aspx ... 404"</p>
  
  <p>Absolutely no useful information AT ALL is given to us by IIS about WHAT the resource or dependencies that it is looking for is.</p>
  
  <p>Any clue as to what might be different or how to find out?</p>
