The command-line tool used to join a computer to a domain is Netdom.exe. This tool is specifically designed for managing domain joins and other Active Directory tasks from the command line. It allows you to join computers to domains and perform various domain-related operations, such as managing trust relationships between domains and resetting machine accounts.

While PowerShell is a powerful scripting language and shell that can also execute commands to join domains, it operates at a higher abstraction level than Netdom and generally serves a broader range of tasks. Cmd.exe is the command prompt that serves as an interface for running various commands, but it does not have built-in commands specifically for joining a domain. Dsjoin.exe is another related tool that can be used for various tasks regarding domain joins but not primarily for joining computer accounts through a straightforward command. Therefore, Netdom.exe is the most appropriate and dedicated tool for this specific purpose.
