Case of the decommissioned DHCP Server

So a client decommissioned several DHCP servers improperly.  So every time you opened the DHCP Console, it displayed those servers even though they have been gone for some time now.

Open ADSIEDIT.MSC
Connect to the configuration container
navigate to CN=configuration,CN=Services,cn=Netservices
In the right pane, Double-click the CN=DHCPROOT entry
Find dhcpServers, remove the names of the decommisioned servers.

    Hi,

    Thanks for the post, however what if your current authorised servers do not appear in the CN=DhcpRoot?! : /

      That's an interesting question. Curious, is your server clustered? what domain function level are you at?
