OpManager v12 not recognizing Windows Server 2012 R2 host

OpManager v12 not recognizing Windows Server 2012 R2 host

I have a Windows 2012 R2 server that OpManager can ping and the credentials test succeeds, but it can't identify it as a server. If I manually associate it with the Windows Server 2012 R2 device template, the dials all work but it continues show the category as 'Unknown' and the Status as 'Device Not Monitored'.
