Retrieve Domain Admins Members of every domains in the forest; and Enterprise Admin

I have edited my first post, so Mike answer is no more appropriated (sorry Mike).

Is there a way to programatically retrieve the Schema Admins Members and the domain Admin members of every domain in my forest ?

I dont want to enter manually the basedn of each ones; and moreover if there is a group that is member of the Domain Admins group, I would like to retrieve the members of these groups too.

Is there an easy way to do that ?

(At the beginning, I was using EnumGroup.vbs, from this website : http://www.rlmueller.net/List%20Members%20of%20a%20Group.htm)

Thank you
