    I’m having the exact same issue on a domain controller. Just out of no where, I started receiving the “Windows is not genuine” error. Nothing new has been installed on this server so I am scratching my head. Microsoft has been no help. I wish we knew the ultimate cause/fix for this because I simply cannot reload a domain controller.-
