title: Internet Explorer: SCRIPT7002: XMLHttpRequest: Network Error 0x2f7d, Could not complete the operation due to error 00002f7d
body: <p>This problem is driving me nuts. Our web app uses HTTP POST to login users and now IE 10 is aborting the connection and saying: </p>
  
  <pre><code>SCRIPT7002: XMLHttpRequest: Network Error 0x2f7d, Could not complete the operation due to error 00002f7d.
  </code></pre>
  
  <p>Here are all the details I have</p>
  
  <ul>
  <li>IE version 10.0.9.16618, update version 10.0.6. I've also reproduced this on IE version 10.0.9200.16635, update version 10.0.7.</li>
  <li>The domain is using HTTPS. The problem doesn't occur on HTTP connections</li>
  <li>I've read that for some reason IE needs to get a certificate before it can do an HTTP POST, so I have HTTP GETs running before my POST request, but now the GET is erroring out. See network flow screen shot. The GET is super simple, just a PING page that returns "I'm up."</li>
  <li>Asyn is turned off $.ajax({type: 'POST',url: url,async: false...}); I've read in other posts that this matters.</li>
  <li>The certificate is good, see screen shot.</li>
  <li>The problem goes away if the site is added as a "trusted site" but that's not really the user experience we're shooting for.</li>
  <li>This just started about a month ago. Did Microsoft push some new updates recently?</li>
  <li>I've already read: <a href="http://social.msdn.microsoft.com/Forums/windowsapps/en-US/dd5d2762-7643-420e-880a-9bf75554e383/intermittent-xmlhttprequest-network-error-0x2f7d-could-not-complete-the-operation-due-to-error" rel="noreferrer">http://social.msdn.microsoft.com/Forums/windowsapps/en-US/dd5d2762-7643-420e-880a-9bf75554e383/intermittent-xmlhttprequest-network-error-0x2f7d-could-not-complete-the-operation-due-to-error</a>. It doesn't help.</li>
  </ul>

  <p>Any help is greatly appreciated. I've spent a lot of hours on this with no luck. As you would expect this works fine in Chrome and Firefox. If you need any more detail about what's happening please let me know.</p>
  
  <p>Thanks,</p>
