I am using the computer for ages and will tell you about what does a domain controller do, and what actually it is.

Definition-

A domain controller (DC) is a server that responds to security authentication requests within a Windows Server domain. OR

A domain controller is a server that manages network security, effectively acting as the gatekeeper for user authentication and authorization. Domain controllers are particularly relevant in Microsoft directory services terminology, and function as the primary mode for authenticating Windows user identities.

These are the functions of the domain controller –

Domain controllers host and replicate the directory service database inside the forest. The directory service also provides services for managing and authenticating resources in the forest. These servers host essential services in AD DS, including the following:

1) Kerberos Key Distribution Center (CDC)

2) NetLogon (Netlogon)

3) Windows Time (W32time)

4) Intersite Messaging (IsmServ)
