Adding a system to a domain involves the following steps:
Verify that the system meets the requirements for joining the domain, including a compatible operating system and network connectivity.
Access the system's properties or settings and navigate to the "Computer Name" or "System" settings.
Click "Change" or "Network ID" to initiate the domain joining wizard.
Enter the domain name and provide the necessary credentials for a user with administrative rights in the domain.
Follow the prompts to complete the domain joining process, which may involve restarting the system.
Once joined, the system becomes a domain member, allowing access to domain resources and compliance with domain policies.
