The rules and definitions for creating and modifying object classes and attributes within Active Directory are contained in the Active Directory Schema. The schema defines the types of objects (such as users, groups, and computers) and their attributes, as well as the relationships between them. It can be modified using tools like Active Directory Schema snap-in or Windows PowerShell, allowing administrators to customize the directory according to organizational needs. Changes to the schema are critical as they affect how data is stored and accessed within Active Directory.
The Active Directory administrative tools can only be used from a computer with access to a domain. The following Active Directory administrative tools are available on the Administrative Tools menu: Active Directory Users and Computers (dsa.msc) Active Directory Domains and Trusts (domain.msc) Active Directory Sites and Services (dssite.msc)

DCPROMO Unattended Installation
Contains a < domain > container (for example, the abc.com container), which stores users, computers, groups, and other objects for a specific Windows domain (for example, the abc.com domain). Updates to the < domain > container are replicated to only domain controllers within the domain and to Global Catalog servers if the update is made to an attribute that is marked for replication to the Global Catalog. The < domain > container is displayed in the Active Directory Users and Computers console. The hierarchy of domain directory partitions can be viewed in the Active Directory Domains and Trusts console, where trust relationships between domains can be managed.
Active Directory stores information about all the objects, resources on the network, policies applied on them and permissions on the resources..objects can be users, computers, printers etc
