A built-in group on Microsoft Windows Server family networks. The Domain Admins group simplifies administration of users on the network. It is a global group and does not have any preassigned system rights. The initial membership of the group is the sole user account called Administrator.
Other user accounts that are added to this group gain rights and privileges equivalent to those of the Administrator account and can perform actions similar to those of the Administrator account. All network administrators in a given domain should be members of this group.
On Windows 2000–based networks, the Domain Admins group is created by default in the Users organizational unit (OU) within Active Directory.
