Remote Installation Services(RIS)

Hello friends in this post i am going to told you about one of the most important aspect of the practical networking.In this post i told you about the Remote Installation services shortly named as RIS.

Remote Installation Services (RIS) is an automated installation technology that you can use to create installation images of operating systems or of complete computer configurations, including desktop settings and applications. These installation images can then be made available to users at client computers. RIS is typically used during large-scale deployments when it would be too slow and costly to have administrators or end users interactively install the operating system on individual computers.
Compared to a standard interactive installation, RIS decreases installation time, eliminates the need to use CDs during installation, and minimizes end user and administrator interaction during installations. To accomplish this, RIS relies on Pre-Boot eXecution Environment (PXE) technology. PXE technology enables computers without an operating system to start up and connect remotely over a TCP/IP network connection to a RIS server, which then installs an operating system. The client computers must support remote booting with the PXE ROM, or they must be started with a remote-startup floppy disk and have a network adapter that is supported by that disk.
To perform a RIS installation, an administrator or end user typically boots a client computer from a PXE-capable network adapter by pressing F12 early in the startup process. This instructs the computer to acquire an IP address and connect to a RIS server. The client computer then downloads a small version of the Windows Setup program from the RIS server. You can configure a RIS installation so that the Windows Setup program interactively steps the administrator or end user through a shortened setup process, or you can configure it so that the entire setup process is automated after the end user or administrator presses F12. Also, you can configure a RIS installation so the installation is image-based or setup-based. By using image-based installations, you can deploy applications with an operating system. By using setup-based installations, you have more flexibility in terms of handling hardware differences among the computers in your organization.
