                            7.1.     RIS S ERVER Remote Installation Services (RIS) supports remote installations of Windows Server 2003 operating systems. This means that you can initiate RIS-based installations remotely on a computer without being physically present at the computer.   Use Remote Installation Services (RIS) to simplify the installation of operating systems on client computers in your organization by performing remote image- and CD-based installations on client computers with no operating system or on failed computers that need restoration of the operating system. RIS enables you to create, maintain, and quickly install identical operating system and software configurations on multiple remote client computers with a predefined level of end-user interaction.   RIS uses Pre-boot execution Environment (PXE) technology to enable client computers without an operati...

  6.1. DHCP SERVER Dynamic Host Configuration Protocol (DHCP) is a client-server technology that allows DHCP servers to assign, or lease, IP addresses to computers and other devices that are enabled as DHCP clients. When you deploy DHCP servers on your network, you can automatically provide ip address on client computers.   What Is DHCP? DHCP uses a client-server relationship to allocate addresses, track their usage, and reclaim a Predetermined list of IP addresses and other configuration information shared in a network of Systems. Each organization has one or more DHCP servers with a range of predefined IP addresses, as well as other startup information or additional parameters. When a user boots a client system, that system broadcasts a request for a DHCP server to issue it an IP address.   6.2. Where DHCP Is Useful :- The most common usage of DHCP is to move the management of IP addresses away from the distributed client systems and onto one o...

  5 .1.    What is a DNS server      Domain:- A logical grouping of networked computers in which one or more of the computers has shared resources, such as a shared folder or printer and in which all of the computers share a common Active Directory. Each domain has a unique name.   Domain Name System (DNS) :- Is the name resolution protocol for TCP/IP networks, such as the Internet. Client computers query a DNS server to resolve memorable, alphanumeric DNS names to the IP addresses that computers use to communicate with each other. DNS is a hierarchical caching directory keyed by name, with an extensible set of attributes which are associated with names.   5.2.    Benefits of Active Directory (AD):- Basically, Active Directory improves upon the domain-based architecture of Windows NT to provide a directory service that is better suited to todays distributed networks. AD acts as the central authority for netw...
