Windows Active Directory vs. Domain Controller

Windows Active Directory (AD) and a Domain Controller are closely related but serve different roles in a Windows network environment:

1. Windows Active Directory (AD):
   - Active Directory is a directory service and database provided by Microsoft for Windows domain networks.
   - It is a central repository for network resources, including user accounts, computers, groups, printers, and more.
   - AD provides services like authentication, authorization, and centralized management of network resources.
   - It allows administrators to set and enforce security policies, manage users and devices, and facilitate efficient resource access in a Windows domain.

2. Domain Controller (DC):
   - A Domain Controller is a server that runs the Active Directory service.
   - It is a critical component of an Active Directory domain.
   - The DC authenticates users, enforces security policies, and maintains the directory database containing information about all network objects.
   - Multiple domain controllers can exist within a single Active Directory domain to provide redundancy and load balancing.
   - Each domain controller within a domain replicates changes to the directory database to ensure data consistency and fault tolerance.

In summary, Active Directory is the broader concept and service responsible for directory services and centralized management in a Windows network. A Domain Controller is a server that runs the Active Directory service, and multiple domain controllers can exist within an Active Directory domain to ensure reliability and fault tolerance. The domain controller is a critical component of the Active Directory infrastructure.
