What is the first step to add a workstation to a domain?

To add a workstation to a domain, the first step typically involves accessing system settings related to network configuration and domain settings. The Control Panel serves as a central hub for configuring a variety of system settings, including those necessary for network and user account management. Within the Control Panel, users can find options to manage network settings, such as accessing the System Properties where domain settings can be modified.

Initiating the process from the Control Panel aligns with standard procedures for managing system configurations. Other options, while potentially relevant in different contexts of managing a computer, do not directly provide immediate access to the domain joining process. Thus, starting at the Control Panel is the most logical and appropriate first step in adding a workstation to a domain.
