windows 8.1 The proxy server isn’t responding


  • A Windows 8.1 device behind a corporate ISA 2006 proxy server.  Proxy settings are set correctly.    IE11 responds for all external URL calls with the message:  'The proxy server isn’t responding', and gives the correct proxy name and port. Google Chrome has no problem, and can open all external web pages (as in this post).  Neither Chrome or IE11 can access the web when proxy settings turned off or set to automatic, as would be expected.  This appears to be a problem with IE11.  And as an added bonus, none of the Windows 8.1 apps can see the internet either, but they couldn't see the web in Windows 8.0, so they continue to maintain their complete uselessness.

  • An update to the above post. The issue occurs when the device is started on the corporate network before the proxy settings are set (as in, when connecting after being out of the office).  Configuring the proxy settings give the result as above.  If the device is then rebooted with the proxy settings configured, IE11 can connect to the web through the proxy server.  Windows Store apps still don't connect :(.
