Why would we want to create a central store?
This syncs all policy definitions to all Domain controllers so that if you update or add admx files they are available on all domain controllers and policies show up correctly.
- Check if a central store has already been created by editing a GPO and browsing to Administrative templates it will either show Policy definitions retrieved from local computer or central store. In this case it is showing local computer.
- Copy the folder C:\Windows\PolicyDefinitions to C:\Windows\Sysvol\domain\policies
- Now when you edit a policy it will show that the definitions have been retrieved from the central store.
