Active Directory and its Components Domain Controllers An

Active Directory and its Components • Domain Controllers: An Active Directory domain provides a centralized identity store trusted by all domain members—all computers that have accounts in the domain. • A domain also provides a centralized authentication service. • The two most important elements of Domain Controllers are: 1. The Active Directory database (ntds. dit) and its supporting files contain the definition of objects and the configuration of objects. Examples of objects are Containers, Organizational Units, user accounts and computer accounts. 2. The Active Directory System Volume (SYSVOL) is an SMB-based network share, used to share files with Active Directory members

There are two different types of domain controllers: 1. Read/write Domain Controllers These Domain Controllers allow changes to their Active Directory databases and System Volumes from Active Directory members and can be used to bring changes to other Domain Controllers. 2. Read-only Domain Controllers are Domain Controllers that only allow read-access to their Active Directory databases and System Volumes. Objects: Each object within the Active Directory configuration is identified with a security identifier, the SID. The security identifier consists of two parts: The domain identification part and the relative identifier,
