One of my main responsibilities at my job is managing our Group Policy. It works best with a well thought out structure in Active Directory but you should have that anyways for organization purposes.
I’ll often hear discussions or see comment threads of new IT Professionals wanting to move to centralized management. They might have just gotten the hang of AD structure but Group Policy sounds too good to be true. I have taught some crash courses on Group Policy before but it can be a difficult subject for people to grasp and intimidating to get started with. There are a few key concepts and if you have an understanding of your environment, it should all click nicely. But first, you have to get started some where.
