I needed to find a way to set Automatic browser configuration defined but not enforced, permitting the users to select a custom proxy server or then custom proxy.pac, and if needed rollback to default. So we should have the it configured, but not enforced in GPO (Internet Explorer Maintenaince).
To achieve this we took the below steps:
1. Changing the ‘Automatic Browser Configuration’ setting in Internet Explorer Maintenance GPO to – ‘Not Configured’
2. Setting the proxy from the following registry key and set to apply once-
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\AutoConfigUrl
After applying these settings the Use Automatic Config Script in Lan settings always goes blank and the check box unchecked after every gpupdate or reboot, whereas it should keep the users change intact(if made) or keep the original config script path.
Please help me understand where this is going wrong and how to get around this or if there are some different settings to achieve this?
