You can use these settings to define which client computers this server will respond to. Known clients are the clients that you have prestaged in AD DS. When you prestage a client, you create a computer account object in AD DS that is mapped to a physical computer. Then when the physical computer performs a PXE boot, the operating system will be installed based on the settings that you have defined.
