I have 2 DHCP servers that I have had to replace. On I unauthorized the old servers and when I go to authorize the new servers, it is added to the authorized list but the IPV4/IPV6 areas still show not authorized. It looks like this:

I have restarted the DHCP, DNS, and NETLOGON service and still nothing. What am I doing wrong? I have checked AD Sites & Services > Services > NetServices and servers show up in there as well. Still the new DHCP servers do not show as authorized? How do I get them authorized?

After searching through authorizers I went to the main DHCP server and checked the services to ensure the addresses are in NetServices Attributes. I then restarted that server and when it came back on I restarted the 2 new DHCP servers and the authorized servers started working again. Something was hung up about authorization on the main DHCP server.

    This fixed my issue also. DHCP appeared authorized in AD and even "netsh dhcp show server" showed the correct new servers. I had to reboot the old server to compete the unauthorizing and even the new ones after that.
