I just installed a Win 2016 Essentials, performed the updates correctly, set up the DC and DNS and then when I tried after a reboot to add the DHCP role, I got the message "the operation cannot be completed because the server that you specified requires a restart"
I tried to restart the server several times but the message doesn't change :-(
All the updates are installed and the server is activated.
Any idea how to solve this ? A single server without DHCP is not really useful...
