  <p>Last week, I started to receive the following message while trying to stream files in ie8</p>
  
  <blockquote>
    <p>Unable to download [file] from [server]</p>
    
    <p>Unable to open this Internet site.  The requested site is either unavailable or cannot be     >found.  Please try again later.</p>
  </blockquote>
  
  <p>I do not get the error after updating to ie9 but most of my users still use ie8. I have a feeling this might be related to a windows security patch, but I have not found anything like this from my Google searches.</p>
  
  <p>Here is some more information:</p>
  
  <ul>
  <li>The error only happens in ie8</li>
  <li>I am not using https to display a  word document</li>
  <li>The problem started happening last week.</li>
  <li>The error exists on systems that have not been updated for 3 weeks.</li>
  <li>I have this issue on multiple computers using ie8.</li>
  </ul>
