I have just created a sub domain (in a different subnet) and cannot authorise the dhcp scope / server in the new child domain. It returns an error (access denied) which I think is because the administrator is not a member of the enterprise admins group. I cannot get the email@example.com into this group.
The dns zones wont replicate either but the sites have been added to the child dns server under the _sites folders. However, the _kerberos and _ldap srv records point to the local child dns server, not the respective servers in those sites.
On the child domain server, the local dns IP should be 127.0.0.1 right as its running dns locally?
nltest /dsgetdc:child.domain.local /force and nltest /dsgetdc:domain.local /force all return successfully.
nltest /dclist:child.domain.local and nltest /dclist:domain.local also returns successfully.
