Symptoms

Consider the following scenario:
  • You have a computer that is running Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2.
  • From this computer, you configure an HTTP proxy on a server by running a proxy automatic configuration (.pac) file.  

In this scenario, all remote procedure calls (RPCs) from the computer ignore the HTTP proxy. Instead, the RPCs connect directly to the server.
