To implement a delegation to allow a new DHCP server in AD:

Modify the permissions on the DHCP server container object in Active Directory:

Type adsiedit.msc from Start > Run…
Expand from:
Configuration Container[your DC FQDN]

What we need to assign rights is:

1. Right click choose Properties.
2. Choose Security tab, advanced permissions,
3. Add the user or group you want to grant permission to Authorize a DHCP Server.
4. Grant Allow Full Control right (select “This object and all descendant objects”).

NOTE: You may also need to grant this user “Allow logon locally” rights to
that machine
