Hiding Parent Domain from Child Domain in ADUC

In some environments they use parent domain just for security purposes. If I am not wrong, if they do not want domain Admins to be Enterprise Admins the creation of parent domain will do the job, it may also apply when they do not want Domain Admins to be Schema Admins....

Well, the point is how to make ADUC show just the Child Domain , not the parent Domain ?

This is recommended practice for security purposes and reducing your attack surface particularly from internal threats.

What you're asking to do is "security through obscurity". It's a bad practice because it leads to a false sense of security. I don't believe is possible to do, at least not effectively without breaking something else. Group Policy Management Console for example loads in the root domain and you must navigate down the tree to the child domain. You could also accidentally block domain controllers from being able to see resources in other domains. You will always be able to side step hiding it in ADUC as well via some other method.

My advice would be to secure your root domain tightly and your child domains even tighter :) Impliment real-time monitoring (SCOM, Splunk, etc) as well as historic long term log storage (Splunk, etc). Delegate everything, I can really not see any reason to make anyone other than those very few who need to be domain administrators, domain admins. AD has a very granular delegation system in place.

How do you hide the parent domain in ADUC...  I worked in environment like that....when I open ADUC there is no sense that there 's a parent domain.

I've never heard of anyone being able to do this with Active Directory Users and Computers. By default the root of ADUC is the FQDN of the domain and I do not believe it is possible to alter it. Maybe you are thinking about Active Directory Administrative Center which is a more helpdesk orientated tool but I am sure even that has the ability to view the parent node.

Yeah I don't think there's any options for this.  Best you could do is use Delegation to restrict them from doing anything in the parent domain level.
