Microsoft Active Directory states that it is a database and a directory service. It’s an identity management and access management system that allows you to determine the rights of those who can access your network. Businesses rely on Active Directory to manage their networks efficiently.
In the form of a database, Active Directory allows you to save user-related information, like emails, phone numbers, passwords, and more. A directory service permits users to authenticate their access to resources and andccess for other users on the network.
What is Active Directory Domain Services (AD DS)?
Domain controllers (DCs) are Active Directory servers that host AD DS. DCs handle the security and authentication and security of Active Directory objects. DCs constitute the primary elements of the Active Directory environment and, thus, must be available and operational at all times. DCs are engineered to be dependable and fault-tolerant. Clients and applications use the Lightweight Directory Access Protocol (LDAP) to communicate with DCs. An LDAP query can be used to pull data from Active Directory databases. Active Directory objects are stored within DCs. When an organization has diverse DC information, any changes will be duplicated logically.
Global Catalog (GC) Global Catalog (GC) is an information storage catalog that can be compared to the book index. The GC server functions as a DC, making finding and identifying Active Directory objects from any domain within the forest more straightforward. The GC server has a backup of all objects within its domain and an incomplete duplicate of objects belonging to other domains of the forest. The GC server manages this using AD DS, the AD DS replication system.
Active Directory Schema Structure
The distinct names cn=schema and cn=configuration may refer to the schema partition. The dc is ForestRootDomain. Nevertheless, Doma storeses the various partitions within the same database table, called Ntds. dit.
Below is a diagram that illustrates the difference between the physical and physical place that is part of the schema. The figure below illustrates the distinction between the physical and logical location of the schema. The schema and schema are both physically placed within the schema partition. However, the logical place of the container for the schema is located under the container for configuration. The schema containers are accessible with ADSI Edit snap-in,e, AD schema MMC snap-in or ADSI Edit.
Active Directory Schema Types
It’s a schema that outlines the guidelines for objects and attributes that may be kept inside. It is comprised of two kinds of objects: classes and attributes.
Classes: Classes are templates used to construct active objects that are part of the directory, such as computers, users, groups, and users. The classes don’t contain any particular information regarding the individual or object; however, they offer an additional outline for creating the objects.
Attributes: These attributes describe the properties and characteristics of a particular class. They define the specific details that are kept within the object. Attributes are specified at the time of schema creation and are shared between many courses.
How to Backup Active Directory Schema
Backup of the Active Directory schema is a simple yet essential task. Here’s the desirable way to back up your Active Directory schema efficaciously:
Choose a Backup Solution Choose a reliable backup service that integrates with the AD environment. Cayosoft Guardian offers automated backup methods specifically adapted to Active Directory.
Schedule regular backups: Create an outline of your routine backup schedule. It’s recommended that you back up the AD schema at least once a week each week, or more often, based on the frequency of changes within your system.
Examine the Restore Process: Regularly check the restoration process to ensure that your backups work and are reliable in an emergency.
Secure Backups: Store the backups in a secure, safe location to protect them from physical injury or theft.
Making changes to the Active Directory schema
Another option for altering your Active Directory schema is to develop a program that utilizes Active Directory Service Interfaces (ADSI) to call functions to modify the schema. It is the desirable method if you need to change the schema across all of your employees or you wish to automatize changes made to the schema.

Utilizing the Command Prompt to determine the latest AD schema version
Log into your Active Directory Domain Controller account.
Select Start Menu, Right-click Command Prompt, hover over More, and select Run as Administrator.
Run the command query * cn=schema,cn=configuration,dc=,dc= -scope base -attr object version.
Check the value of objectVersion from the outcome with the table below. For this instance, the value for objectVersion is 87, the AD Schema version of Windows Server 2016.
