You can use Windows Deployment Services to link client computers to computer account objects in Active Directory Domain Services (AD DS). This is called prestaging a client. Prestaged clients are also called “known computers”. For those computers that are not known, you can configure the Auto-Add policy to require administrative approval before they will be allowed to boot against the server to install an operating system. In addition, you can configure an unattended installation for clients in order to automate the Windows Deployment Services client and the later stages of Windows Setup.
