Computer accounts or objects represent devices connected to the AD. They are stored in AD database after connecting to the domain. This is needed to apply different GPOs to them and keep track of their updates if you have WSUS installed. And what is more important establish secure authentication for users logging into Windows.

In order to join a workstation to a domain, the device needs to be in the same network with domain controllers. It is also possible to join a device through a VPN. In this case device needs to be able to resolve the name of the AD environment. DHCP can definitely help with that but you can also do this by adding the domain information to the hosts file.

How to Join a Computer to the Domain

 

It is possible to join a computer to the domain in three different ways, lets see how to do this on practice.
