Answer : What is the difference between members in Admistrators and members in Domain admins.

I should correct my last statement, actually I have just tested, members of Administrators group have full and unrestricted access to DC, entire domain and all computers. Administrators group has by default three entries in forest root domain:
Administrator user account, Domain Admins and Enterprise Admins group.

Because scope of Administrators group is domain local, this group is not seen in any other domain. I believe that's why Domain admins group exists, so that  you can use it on other computers in domain or in other domains. This is a part of A G DL P strategy of using groups.
