So far we have been creating GPOs and putting settings into them, so we are well aware of what is happening with each of our policies. Many times, though, you enter a new environment that contains a lot of existing policies, and you may need to figure out what is happening in those policies. I have had many cases where I install a new server, join it to the domain, and it breaks. It doesn't necessarily nose dive, but some component won't work properly or I can't flow network traffic to it for some reason. Something like that can be hard to track down. Since the issue seemed to happen during the domain join process, I suspect that some kind of policy from an existing GPO has been applied to my new server and is having a negative effect on it. Let's take a look inside Group Policy at the easiest way to display the settings that are contained within each GPO.
