Basic Concept Domain Security Authority and Active Directory

Author : Admin

Domain concept in the Microsoft Windows was introduced by Microsoft in Windows NT technology such Windows NT 4.0, Windows 2000 and other Microsoft Windows based on NT. A domain defines as the first place a management boundary. It’s an administrative grouping of users, machines and resources that can be managed by the same domain administrator whereby a user may be granted access to a number of machines and resources with the use of a single username and password combination. It’s called single sign on ( SSO ).


In the Microsoft Windows 2000 onwards, a domain is also an active directory namespace and a replication partition. An Active Directory namespace defines the subset of the data stored in Active Directory that is replicated and kept synchronized between Active Directory copies on different domain controllers. What is Active Directory ..? Active directory is a logical grouping of users and computers centrally managed by servers called domain controllers.


A Domain Controller ( DC ) is a domain’s security authority. It hosts the domain security database and authenticates security principals that want to access the resources that are part of the domain. So a Domain Controller ( DC ) is a server that responds to security authentication request such as logging in, authority, checking permission and other within the Windows Server Domain. See detail about Domain and Active Directory Service at Microsoft site.
