Once the OS Chooser environment has been booted, the user must authenticate against the Domain Controller, and can then select a Windows image to install.
The source files for each image can be customized with 3rd party utilities such as nLite to slipstream updates and service packs, apply tweaks, perform unattended installations, and include software with the operating system.
Remote Installation Service utilizes UDP port 4011[3] to provide clients the contents of each page the OS Chooser displays.
This allows servers to run the install automatically, eliminating the need for dedicated hardware or personnel at each facility.
The primary benefit of remote replication is reduced cost and complexity of managing multi-site organizations.
