Recently we have upgraded all the IE 9 to IE 11. The testing went well but didn’t realize that we found an issue after implementation.
The certain group policy settings which are applied to IE9 are deprecated. One of them is proxy settings.
We push the proxy settings through GPO, soon after the IE9 upgrade to IE11, the proxy settings stopped applying
So, to fix the problem, we need to have set of GPO settings that is applicable to IE11. There is a catch.
You need to have at least one windows 2012 server (member server) for creating and applying the policy.
There are 2 ways to fix it
- Find the list of registry changes that the GPO is going to make to the client system for IE 11 and create GPO registry preference
- Install a new windows 2012 member server and create the policy using that
