DOMAIN

What is a Domain?

Windows domains provide network administrators with a way to manage a large number of PCs and control them from one place. One or more servers — known as domain controllers — have control over the domain and the computers on it. Domains are generally made up of computers on the same local network. However, computers joined to a domain can continue communicating with their domain controller over VPN or Internet connection. This allows businesses and schools to remotely manage laptops they provide to their employees and students.
When a computer is joined to a domain, it doesn’t use its own local user accounts. User accounts and passwords are managedon 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.
Network administrators can change group policy settings on the domain controller. Each computer on the domain will get these settings from the domain controller and they’ll override any local settings users specify on their PCs. All the settings are controlled from a single place. This also “locks down” the computers. You probably won’t be allowed to change many system settings on a computer joined to a domain.
