How to add child domain user in parent Domain admins group.
e.g
I wants to add B@child.parent.com user in domain admins group of Parent.com.
form parent domain admin/properties/add member >> i am able to see
child.parent.com domain but after clicking it shows no objects are available
in this location.

Please help

You can't - Domains Admins is a global group, which can only contain members
from within the same domain.

Depending on what you are trying to achieve you can use Administrators,
which is a Domain Local group. This group can manage the domain, but will
not by default have administrator access to member computers.





kind regards,
