WIndows 2008 R2: DHCP Authorising

Hi All,

I want to add an additional DHCP to one of our sites.  So I added the role on an existing DC, however the follow message appeared in the event log.


The DHCP/BINL service on the local machine, belonging to the Windows Administrative domain mydomain.local, has determined that it is not authorized to start.  It has stopped servicing clients.  The following are some possible reasons for this:
      This machine is part of a directory service enterprise and is not authorized in the same domain.  (See help on the DHCP Service Management Tool for additional information).

      This machine cannot reach its directory service enterprise and it has encountered another DHCP service on the network belonging to a directory service enterprise on which the local machine is not authorized.

      Some unexpected network error occurred.


Any ideas / or suggestions?

The DHCP server needs to be authorized in AD.
It can be done from the DHCP console.
