7.9 Unauthorizing a DHCP Server from Active Directory Domain Services

A DHCP server is unauthorized from AD DS when the "dHCPClass" object corresponding to the server is deleted from the AD DS.

The filter required to unauthorize a DHCP server is based on its IP address and server name as specified in Unauthorization Filter, section 7.6 .

This filter matches a "dHCPClass" object with the "dhcpServers" attribute matching "i<server ip address>$" and "s<server name>$". Only one such object matches the filter. Delete that object from the AD DS.
