Yes, I have followed these procedures. I've done many installations on several servers without a problem previously. Also, this is an upgrade from 12 to 12 MR1. Frankly I think a a bug was introduced with Endpoint Protection Center 12 MR1 not recognizing a client with Network Threat Protection uninstalled and is reporting it disabled instead. To test this I modified one client adding Network Threat Protection and Endpoint Protection Center has indeed reported this client "up to date."
