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.
The term is active directory dns integrated means that during replication of AD all changed/ updated data is replicated and we dont have to replicate DNS zone files(which contains information aout the dns records) seperately . Active Directory-integrated DNS enables Active Directory storage and replication of DNS zone databases. Windows 2000 DNS server, the DNS server that is included with Windows 2000 Server, accommodates storing zone data in Active Directory. When you configure a computer as a DNS server, zones are usually stored as text files on name servers - that is, all of the zones required by DNS are stored in a text file on the server computer. These text files must be synchronized among DNS name servers by using a system that requires a separate replication topology and schedule called a zone transfer However, if you use Active Directory-integrated DNS when you configure a domain controller as a DNS name server, zone data is stored as an Active Directory object and is replicated as part of domain replication.
