Win10 PC and Web Proxy Issue

Question

Hi,

Am stumped with this one but hopefully someone can help. PC version is Win10 Ent 10.0.18363

We are looking to get rid of our WebProxy and just use our PaloAlto Firewall for filtering web access. To this end we’ve created a GPO that sets IE to not use a PAC file or point to the WebProxy IP, see attachment.

Also, Powershell on PC shows no Proxy. (see attachment)

The thing is, some staff are still going via the WebProxy, including the users PC for the attached pics, who as far as I can tell should not be. Other staff are going out direct through the FW as expected.

Any ideas why this would be, is there somewhere else that could be forcing it via the WebProxy?

Thank you!
