How to Install A New Domain Controller In A Sub Domain

The video provides a tutorial on installing a domain controller on a subdomain in Windows Server 2008. The presenter starts by setting up a new system, assigning it a specific IP, and disabling the firewall. It then uses Server Manager to add active domain service roles and proceeds to install Active Directory. Using the DCPROMO command, it connects the new controller to the subdomain in the existing forest, ensuring that there are no copies of data from the parent domain controller. After installation, the computer restarts, and the user uses Active Directory to manage users and computers in the new subdomain.
