Preparing for AD DS Installation
Starting the AD DS installation
Once the installation is complete, the machine will be required to reboot in order to complete the entire installation. Again the process above is just for adding an additional domain controller to an existing domain, which is important in some interoperability scenarios when partners try to join a Windows domain controller into a non-Windows domain. We can leave the other domain controller promotion processes , such as creating the first domain controller in the forest, creating a child domain or creating a Read-only DC to the future blogs.
