Active Directory Management Tutorial

 

Managing Active Directory, a service provided 
rosoft for Windows-based networks, is a crucial skill for system administrators and IT professionals. Active Directory is used to manage and control access to resources, such as users, computers, and network services in a Windows environment. Here's a tutorial to get you started with Active Directory management:

Note: This tutorial assumes that you have a basic understanding of Windows Server and network concepts. You'll need a Windows Server machine to practice these tasks.

1. Install and Configure Active Directory:

Install Windows Server:

Install Windows Server on a dedicated machine or virtual machine. Ensure it has a static IP address.

Add the Active Directory Role:

Open "Server Manager."

Click "Add roles and features."

Select "Active Directory Domain Services" and complete the installation.

Promote the Server to a Domain Controller:

After role installation, promote the server to a domain controller.

Follow the wizard, create a new forest or join an existing one, and set the Directory Services Restore Mode password.

Configure DNS:

Install the DNS role if it's not already installed.

Ensure the DNS server is integrated with Active Directory.

Reboot the server to complete the promotion.

2. Active Directory Management:

User and Group Management:

Create User Accounts:

Open "Active Directory Users and Computers" (ADUC).

Navigate to your domain, right-click, and select "New" > "User." Follow the wizard to create a new user.

Create Groups:

In ADUC, right-click on the "Users" or another appropriate folder and choose "New" > "Group."

Manage Group Memberships:

Open a group's properties and add or remove members on the "Members" tab.

Organizational Unit (OU) Management:

Create OUs:

In ADUC, right-click on the domain and select "New" > "Organizational Unit." Create OUs to organize users and computers.

Delegate Control:

Assign specific permissions to users or groups for OUs by right-clicking the OU and selecting "Delegate Control."

Group Policy Management:

Create Group Policies:

Open "Group Policy Management Console" (GPMC).

Create, edit, or link GPOs to OUs to control settings for users and computers.

Active Directory Maintenance:

Backup and Restore:

Regularly back up Active Directory to ensure data integrity.

Use the "Windows Server Backup" tool or a third-party solution.

Monitoring and Troubleshooting:

Monitor event logs for Active Directory-related issues.

Use tools like "Active Directory Administrative Center" and "ADSI Edit" for advanced management.

Security and Access Control:

Implement security best practices, like strong password policies, account lockout policies, and auditing.

3. User Account and Computer Management:

User Account Management:

Reset passwords, enable/disable accounts, and manage user attributes through ADUC.

Computer Account Management:

Add, remove, and manage computer accounts in ADUC.

4. Active Directory Replication:

Understand the concept of Active Directory replication.

Monitor replication status using tools like "Repadmin" and "Active Directory Sites and Services."

5. Active Directory Trusts (Optional):

Learn about creating trusts with other domains or forests for resource sharing.

This tutorial provides a fundamental understanding of Active Directory management. For advanced topics, consider exploring Active Directory Federation Services (ADFS), Active Directory Certificate Services (AD CS), and Azure Active Directory (if using Azure). Regularly update your knowledge with the latest best practices and security guidelines.
