Proxy Auto Config (pac) file which is pushed by Admin is not getting processed correctly resulting in not able to access Internet at all. 

This process is working for Windows 8 with IE10 but not working with Windwos 8.1 E11.

When we provide pac file address to local folder i.e. file://c:\windows\temp\proxy.pac this is not getting processed. When we changed the path to Websense appliance directory http://(websense appliance name):8083/proxy.pac, this is working.

Please see this article about changes that were made to the way IE 11 handles local PAC files. Local PAC files are. Ow disabled. You have to create a reg entry to revert back. Nice huh.

Same issue, even in file://c:/windows/system32/drivers/etc/proxy.

http seems to be the only accepted location.

We are having the same issue. We can move the pac file to a http address and it works. If we leave the file in C:\windows\proxy.txt or c:/windows/system32/drivers/etc/proxy it just ignores the file. But this isn't a solution since we need the pac file to be local for security reasons. We have also tried you response with file://c:/windows/system32/drivers/etc/proxy and that doesn't work either.

One other thing I noticed is IE 11 also doesn't respond to the java alert("Hello World") command. This is used a lot for testing the pac file to see if certain areas are functioning. This works in IE 10 and below.

Can you please look into this issue further?

Thank you for your feedback.

Please try this:
The location for local pac file for IE and the windows platform is:
file://c:/windows/system32/drivers/etc/proxy    next to your hosts file and note there is no extension on the proxy file.

Put this path into IE and see if the browser is able to find the pac file.

Best regards,
