  2. The wizard will run prerequisite checks. If everything is fine, click “Install.”

Step 7: Completion

After the installation is complete, your server will be a domain controller, and it will also act as a DNS server.

Step 8: Managing Active Directory

You can manage Active Directory using various tools:
