Deploying MDATP to 2008 R2 and 2012 R2 servers after installing the required prereq's, Windows Defender is not available. From this URL, is it required to use SCEP? It doesn't seem like it is required if you manually onboard these servers to MDATP. Well, the servers do onboard, but are not really reporting or able to perform Windows Defender actions on them. Suggestions?
