Although you are a domain administrator and DHCP administrator in a child domain, you may receive an "access denied" message when you try to authorize a DHCP server in the child domain.
This issue can occur because you must be an enterprise administrator to authorize a DHCP server.
To resolve this issue, use an account in the parent domain to authorize the server. The DHCP administrator in the child domain can administer the server after the server is authorized.
You cannot add users in the child domain to this group except in native mode.
