IPAM introduction
I started working with the IPAM component of R2 and found this guide helpful. Also, as a note, leveraging GPO for enablement is the way to go, but what's not clear in any of the documentation I have seen is knowing that after you do a server detect, its important to first take any of your cautions (which you may think is a result of being blocked) and making them managed, that then gives them the required GPO. I am still in the middle of working to get past this stage, and will post additional data as I learn it :)
