Add a domain controller to an existing domain – Windows Server 2022

This Windows Server 2022 Tutorial covers how to add a domain controller to an existing domain. Windows Server Active Directory Domain Service (ADDS) is a directory service that stores information about all objects in the domain and makes this data available to network users and administrators. Active Directory Domain Service provides secure, structured, hierarchical data storage for objects and the admin can easily manage all objects. The Active Directory Domain Controller is a server that runs Active Directory Domain Service and domain controllers to give the network user access to permitted resources anywhere on the network through a single logon process. Additional domain controller helps disaster recovery and balances the load.
