title: AppPool Permission Issue with Accessing Report Server
body: <p>I have a SQL Server 2008 R2 Report Server running on a Windows 7 machine as well as an ASP.NET application. The ASP.NET application makes requests to the Report Server to display a list of reports, render reports, etc. My ASP.NET application successfully gets the list of reports but when it tries to render a report I get the following error:</p>
  
  <pre><code>The permissions granted to user 'IIS APPPOOL\DefaultAppPool' are insufficient for performing this operation. (rsAccessDenied)
  
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  <p>Note: This same code base has worked fine on multiple machines running Windows 7 and Windows Server 2008. Iv'e been trying many different things based on web searches but haven't found a solution. Any insight into this would be greatly appreciated.</p>
