parent child user

hi all,

Any one plz help me regarding....
I intend to create a parent-child scenerio in my organisation.
as parent.com , child1.parent.com , child2.parent.com.
Is it possible to login the users across these all three domain or not????
As per the MS docs the users in this scenerio can authenticate to any domain
cause two way transitive trust exist in this scenerio by default.....

But in my test scenerio it is not working plz help me.......

David - what exactly is "not working"?
By default, users in a multi-domain forest (which is the configuration you
are referring to) should be able to log on to any computer that is a member
of any of its domains - if this is not happening in your case, what are the
symptoms of the problem you are trying to resolve?
