Networking Managment With Windows Server 2003

Network Management With Windows Server 2003
Like Microsoft Windows XP Professional, Windows Server 2003 groups its administration routines under an ensemble referred to as Administrative Tools. Unlike the former, the later provides various ways of accessing the tools.After you have just setup Microsoft Windows Server 2003 and installed Active Directory, the first window that comes up provides some of the most regular tools you will need to administer the network:The middle section of this window provides only a limited list of tools, considered to be the most regularly used. Alternatively, you can display the whole list of tools in a window. To do this, under the Tools and Updates Section, you can click Administrative Tools:


Network Management With WinXP
Most of the tools used to locally manage a Microsoft Windows XP Professional or a peer-to-peer network are listed in the Administrative Tools window. To open it, you can open Control Panel and double-click Administrative Tools:


MANGMENT OVERVIEW
INTRODUCTIONAs a network administrator, you will perform various tasks to keep the network up and running. These include computers, users (the people who use the network), the peripherals (the other machines attached either to the computers or directly to the network. To make this possible, both Microsoft Windows XP Professional and Windows Server 2003 provide the various tools you will need. If you are managing a peer-to-peer network, the former provides local and possibly small network tools to manage workstations. For a client/server network, Microsoft Windows Server 2003 provides all the tools you need to locally or remotely manage the servers or the clients.


HOW TO MEASURE A NETWORK
Performance parameters:Latency: Time required to transfer an empty message between relevant computers.Sum total ofdelay introduced by the sender software.delay introduced by the receiver software.delay in accessing the network.delay introduced by the network.Data transfer rate: is the speed at which data can be transferred between sender and receiver in a network, oncetransmission has begun. (bit/sec)Message transfer time = latency + (length of message) / (Data transfer rate).Bandwidth : is the total volume of traffic that can be transferred across the network.Max. data rate (bit/sec) = carrier BW · log2 (1 + (signal/noise))this maximum (Shannon's Limit) is theoretical, not reacheable in practice!Ex.: phone line BW = 3 kHz, S/N = 30 dB = 1000 "src="http://users.ictp.it/~radionet/1998_school/networking_presentation/pictures/arrow_forward.GIF" width=20 align=absMiddle border=0> Max. data rate = 30 kbit/sec


WHY A COMPUTER NETWORK ?
The main reasons are:Distribute pieces of computation among computers (nodes)Coordination between processes running on different nodesRemote I/O DevicesRemote Data/File AccessPersonal communications (like e-mail, chat, audio/video conferencing)World Wide Web... and many other uses


Introduction to Client-Server Networks
The term client-server refers to a popular model for computer networking that utilizes client and server devices each designed for specific purposes. The client-server model can be found on the Internet as well as local area networks (LANs). Examples of client-server systems on the Internet include Web browsers and Web servers, FTP clients and servers, and DNS.
