Deploying Proxy
PAC file configuration through GPO-GPP – Registry update method:
I had received request from our team to setup the proxy PAC
file configuration for VDI clients, hence I started preparing the GPO with User
configuration settings.
They had mentioned that PAC
file configuration which we set in the IE -Connections - Lan Settings should
be editable by users, hence I
decided not to use the GPP-
Internet Settings to deploy the IE configuration based on the IE version target.
Solution:
Created the New GPO for testing the new Registry Item for
Proxy PAC configuration.
Updated the “AutoconfigURL” settings with PAC file Path on
below registry path in User configuration.
HKCU\Software\Microsoft\windows\CurrentVersion\Internet
Settings
I decided to check and it was working fine for my login and
for the requestor as well...
After two or three days, few customers complaint that the
proxy configuration is not displayed for them.
So, I logged into to those servers / clients where customer
reported the issue … this is the first time I logged on to those servers. Surprisingly,
GPO which I had setup does not apply in IE proxy configuration script option but GPRESULT report shows that registry item is processed.
I started to blame the IE Enhanced Security Settings but I checked
it was in disabled Mode for both Administrators and Users.
In the problematic system, I manually tick the “Use Automatic Configuration Script” and
Un-ticked it. Forced the Gpupdate using force switch.
Magic, this time it was applied successfully. I found in
Internet that we others also had similar problem, they had solution by Setting
the following registry Key.
Seems, to be working fine till now. Hope, this will be helpful for you as well...
