Hi All,
We've recently had an issue for a few users where Internet Explorer isn't using the PAC file correctly. It shows as being configured correctly, Chrome is setup to use system proxy settings & works correctly with the PAC file.
Watching network traffic via ProcMon shows that IE does infact go to the server hosting the PAC file first, but then proceeds to try browsing directly to the internet rather than via the correct Proxy server.
- Have confirmed that pasting the PAC file location into the address bar downloads the file (although it has an _ instead of . in the filename... is that a clue?)
- Same issue occurs when running IE as another user (right click/run as other user)
- Have cleared IE Temp Files
- Removed the PAC configuration, restarted IE & reset the PAC location
- Restarted WinHTTP Autoconfig service (I believe this is moreso for WPAD, though have seen it help in the past)
- Setting the proxy server manually works, its just when trying to use the PAC file that is a problem
Where should I be looking next? I'm at a loss...
Cheers
Jason
