  <p>We are getting above said error from our production server which is hosted in SharePoint farm environment, where as not able to reproduce the same issue from our staging server which is standalone server.</p>
  
  <p>I hope, the above said error will be throwing when Microsoft.Office.Word component accessing from remote machine. I've updated all users under "Launch and activation Permission" in DCOMConfig as mentioned in <a href="https://stackoverflow.com/questions/10139834/retrieving-the-com-class-factory-for-component-with-clsid-error-8000401a">Retrieving the COM class factory for component with CLSID Error: 8000401a</a></p>
  
  <p>The interesting here is, the issue has been resolved automatically when user keeps clicking on the "Report Generation" button in my web page. I understand the issue seems to be happened on occasionally as we cannot predicate when this will be thrown.</p>
