Windows Server – Old DHCP Servers appear in the list of Authorized servers

After migrating the Actitive Directory domain services from 2008R2 to 2016, the next step was migtate DHCP server to new WS2016 server and add secodn DHCP server on the second Domain Controller – i using DHCP failover.

But when i opened „Manage Authorized Servers“ in DHCP console i saw the „Server01.xxxx“ – old DHCP server, so i need remove it, you can use NETSH command in command line.

Netsh DHCP delete server ServerFQDN ServerIP address”
in my case:
Netsh DHCP delete server server01.xxx 10.146.xxx
