What is Domain Controller?

Domains have been around since 1993 with the release of Windows NT.They Provide System Administrators in an efficient way to manage small or large Networks.You only Need one Domain Controller to manage a large number of computers on the same network.A Domain Controller is any server that has the AD DS or Active Directory Domain Services role installed.The Server job is to Handle authentication requests across the domain.Domain Controllers hold the tools Active Directory and Group Policy among others so when you need to create a new user account or change the main policies this is all done by a domain controller.

You can have several domain controllers within a domain but there is only one primary or main domain controller.The Primary reason for having more than one DC is fault tolerance.The Critical Information like user and account information is replicated between the DCs So, If One goes down the client computers will switch to other DC that is still functioning.Domain Controller uses a tool called Active Directory Users and Computers commonly referred to as AD or Active Directory.This tool is not only managed user and computer accounts but also acts as a directory service for resources on your network like printers or file shares.When a domain user searches for a new printer to install, they will find all the printers that have been added to the domain controller with Active Directory.
