Active Directory NC (Naming Context's)
The Schema and Configuration partition
Active Directory NC (Naming Context's) * Active Directory consists of three partitions or naming contexts (NC) ** Domain, Configuration and Schema Naming Contexts * Each are replicated independently * An Active Directory forest has single schema and configuration ** Every domain controller (DC) holds a copy of each (schema, configuration NC's) * Forest can have multiple domains ** Every domain controller in a domain holds a copy of the domain NC
Schema
The Active Directory configuration partition is a critical component of the Active Directory architecture that stores configuration data for the directory service itself. It contains information about the Active Directory forest, including the schema, replication topology, and services available within the forest. This partition is replicated across all domain controllers in the forest, ensuring that every controller has consistent configuration information. It plays a key role in enabling the functionality and management of Active Directory environments.
*Schema NC, *Configuration NC, * Domain NC Schema NC This NC is replicated to every other domain controller in the forest. It contains information about the Active Directory schema, which in turn defines the different object classes and attributes within Active Directory. Configuration NC Also replicated to every other DC in the forest, this NC contains forest-wide configuration information pertaining to the physical layout of Active Directory, as well as information about display specifiers and forest-wide Active Directory quotas. Domain NC This NC is replicated to every other DC within a single Active Directory domain. This is the NC that contains the most commonly-accessed Active Directory data: the actual users, groups, computers, and other objects that reside within a particular Active Directory domain

Active Directory service is used to store information about the network resources across a domain and also centralize the network.

An Active Directory Integrated Zone (AD Integrated Zone) is a type of DNS zone that is stored within Active Directory rather than in standard DNS files. This integration allows for enhanced security, redundancy, and dynamic updates, as the zone data is replicated across all domain controllers in the Active Directory environment. It also enables better management of DNS records through the use of Active Directory permissions, allowing for more granular control over who can modify DNS entries. Overall, AD Integrated Zones streamline DNS management in a Windows server environment.
The Sysvol folder in Active Directory is a critical component that stores scripts, group policies, and other data needed for domain operations. It is replicated across all domain controllers within a domain, ensuring consistency. Key subfolders include "Policies," which contains Group Policy Objects (GPOs), and "Scripts," which holds logon and logoff scripts. The Sysvol folder is essential for maintaining domain-wide settings and enforcing security policies across the network.
Active Directory Recycle Bin is a feature that helps minimize directory service downtime by enhancing your ability to preserve and restore accidentally deleted Active Directory objects without restoring Active Directory data from backups, restarting Active Directory Domain Services (AD DS), or rebooting domain controllers. When you enable Active Directory Recycle Bin feature, all link-valued and non-link-valued attributes of the deleted Active Directory objects are preserved and the objects are restored in their entirety to the same consistent logical state that they were in immediately before deletion. For example, restored user accounts automatically regain all group memberships and corresponding access rights that they had immediately before deletion, within and across domains. Active Directory Recycle Bin is functional for both AD DS and Active Directory Lightweight Directory Services (AD LDS) environments. Mohannad Hamid
