My network is configured with 802.1x implemented with a NPS server. I have one computer that would lose connect. Upon checking the event viewer, I saw that the Network Access Protection Agent service was being terminated unexpectedly but not restarting. Without that service running, the computer could not authenticate which in tour would make it lose its connection.
Besides that service, Remote Desktop Services,Network Location Awareness, Workstation, DNS Client, and Cryptographic Services services are also being terminated. Any idea why all of these services are going down? So far when this happens. I am forced to go over to the computer in question and manually start the Network Access Protection Agent service to regain network connectivity.
