title: Report Viewer problem after moving to new server
body: <p>I have just moved a site from a Windows 2003, IIS6 SQL 2005 server to a new one with Windows 2008, IIS7 and SQL 2008.</p>
  
  <p>I am having problems with the Report Viewer.
  I have installed the Report Viewer Re-distributable (I've tried 2005, 2005sp, 2008 and 2008sp)
  I've Mapped a handler in IIS for </p>
  
  <blockquote>
    <p>Reserved.ReportViewerWebControl.axd</p>
  </blockquote>
  
  <p>to type</p>
  
  <blockquote>
    <p>Microsoft.Reporting.WebForms.HttpHandler,
    Microsoft.ReportViewer.WebForms,
    Version=8.0.0.0, Culture=neutral,
    PublicKeyToken=b03f5f7f11d50a3a</p>
  </blockquote>
  
  <p>However whenever I run a report on the website I get the following error message:</p>
  
  <blockquote>
    <p>Could not load type 'Microsoft.Reporting.Microsoft.Reporting.WebForms.HttpHandler' from assembly 'Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
    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>
