-enabled computers to remotely execute boot environment variables. These variables are likely computers that are on a company's (or that company's client's) network. RIS is used to create installation images of operating systems or computer configurations, which can be used to demonstrate the installation process to users whose machines have been granted access to the RIS server. This eliminates the need to use a CD-ROM for installing an operating system.

Background

At boot time, a workstation that has been set to boot from PXE will issue a BOOTP request via the network. Once the request is received, the DHCP Server will supply an

History

Remote Installation Services was introduced with

Windows 2000 Windows 2000 is a major release of the Windows NT operating system developed by Microsoft, targeting the server and business markets. It is the direct successor to Windows NT 4.0, and was Software release life cycle#Release to manufacturing (RT ...

as an optional component when installed on Windows 2000 Server. Initially, it supported only the distribution of Windows 2000 Professional, but with Service Pack 3 allowed for the remote installation of Windows 2000 Server. RIS was updated twice; once to support

Overview

On Windows 2003, two services are required to provide Remote Installation Services:

DHCP The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a clie ...

and Remote Installation Service. The Remote Installation Server doubles as a proxy DHCP server to provide Boot Server and File name instructions to clients. Remote Installation Service utilizes UDP port 4011Service overview and network port requirements for the Windows Server system
Microsoft Inc. to provide clients the contents of each page the OS Chooser displays. Additionally, this service can provide drivers to clients; it is often used to provide the workstation's network card driver, which is required to launch the OS Chooser and mount the share where images are stored.

Installation Using RIS

RIS can be used only for clean installations and cannot be used to upgrade a previous version of Windows. A RIPrep image can contain the operating system and applications. Computers that are connected to the same network as the server, and have been enabled, automatically start the RIS sequence. This process can be automated through what is called Remote Replication. Remote replication allows installations to be sent to a designated network share at a remote office, which can then be run by any system at that location. 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.
