I am working in WS2012R2. I have installed a Windows 7 computer with a domain: mysite.com and added a AD UC user to it and now I am logged onto that AD UC user. I have configured DNS for the IPv4 address and win7.mysite.com. I also made a DHCP Reservation for it also and it is "Reservation(active)".
In Server Manager>All Servers>Servers it lists win7 but the error message says:
"Online - Cannot manage a client-based operating system"
Remember I am logged onto a 'AD Users and Computers' User on the win7 machine.
