Windows domains provide network administrators with ways to administer a great number of devices and control them from a central location. Domains are generally made up of computers on the same local network. When a computer is joined to a domain, it doesn’t use its own local user accounts. User accounts and passwords are managed on the domain controller. When you log into a computer on that domain, the computer authenticates your user account name and password with the domain controller. This means you can log in with the same username and password on any computer joined to the domain.
