70-291 MCSE Guide to Managing a Microsoft
Windows Server 2003 Network, Enhanced Chapter
1Networking Overview
2
Objectives
  • Define a network and describe its usage
  • Describe some of the features of Windows Server
    2003
  • Understand the differences in the editions of
    Windows Server 2003
  • Identify the different types of networks commonly
    found in industry
  • Describe common network protocols and their usage

3
Objectives (continued)
  • Outline the Open Systems Interconnection (OSI)
    model and how it is used as a model for
    transmission of information across a network
  • Recognize the components in the Windows Server
    2003 networking architecture
  • List common networking services available in
    Windows Server 2003

4
Defining Networks
  • Information is usually transmitted between
    computers via different types of media
  • Media attaches to a computer system through
    adapter
  • Network
  • Consists of two or more computers that can
    exchange information through a medium
  • Servers share information or other resources
  • Clients access shared resources

5
Defining Networks (continued)
  • Single computer may be both a server and a client
  • Windows Server 2003 is called a network operating
    system (NOS)
  • Windows Server 2003 is the latest NOS superceding
    Windows 2000 and Windows NT4

6

Windows Server 2003 Installation Hardware
Requirements
19
Windows Server 2003 Installation Hardware
Requirements (continued)
20
Activity 1-2 Determine the Currently Installed
Version of Windows Server 2003
  • The purpose of this activity is to find out which
    version of Windows Server 2003 is running
  • Start ? Manage Your Server ? Computer and Domain
    Name Information ? General tab
  • Observe and write down the version

21
Activity 1-3 Discover the Features of Windows
Server 2003 Enterprise Edition
  • Objective Identify the features of the
    Enterprise edition using the Microsoft webpage
  • Proceed to webpage www.microsoft.com/windowsserver
    2003
  • Click Product Information ? Product Overviews ?
    Windows Server 2003 ? Enterprise Edition Overview

22
Network Types and Protocols
  • Local area networks (LANs) connect computers
    within close proximity
  • LANs are the most common types of networks
  • Metropolitan area networks (MANs) connect
    computers separated by moderate distances
  • Wide area networks (WANs) typically connect
    computers between cities, across countries, or
    even around the world

23
Network Types and Protocols (continued)
  • A network protocol packages information into
    packets
  • A media access method sends packets onto the
    media itself
  • IPv4
  • Most common LAN protocol used today
  • Also the standard protocol used to transmit
    information over the internet

24
Network Types and Protocols (continued)
  • IPv6 offers enhancements to IPv4
  • Both IPv4 and IPv6 are referred to as TCP/IP
  • IPX/SPX protocol
  • Used for backward compatibility with older
    networks
  • Macintosh computers use the AppleTalk protocol

25
Network Types and Protocols (continued)
  • Ethernet is the most common media access method
    used to send TCP/IP packets over a network
  • In the token ring media access method, the
    computer with the token is allowed to transmit
    over the network

26
Activity 1-4 Viewing Available Protocols
  • Objective Verify protocols available for
    installation
  • Make a list of all protocols currently installed
    on the server and all protocols available for
    installation

27
Network Architecture
  • Various hardware and software that allow the
    transfer of information amongst computers on a
    network

28
The OSI Model
  • Open System Interconnection model
  • A seven-layer model
  • Explains the different components used when
    sending or receiving data

29
The OSI Model (continued)
  • Seven layers include
  • Application
  • Presentation
  • Session
  • Transport
  • Network
  • Data link
  • Physical

30
The OSI Model (continued)
  • Server will interact with the application layer
    first
  • Client interacts at the physical layer first

31
The OSI Model
32
The Windows Network Architecture
  • Four main software components that comprise OSI
    client, service, protocol, adapter
  • Network Driver Interface Specification (NDIS)
    resides between protocols and adapter software
  • Transport Driver Interface resides between
    clients and protocols and between services and
    protocols

33
The Windows Network Architecture (continued)
34
NDIS
  • Developed by Microsoft and 3Com
  • Used to speed the development of device drivers
    and enhance networking capabilities
  • Developers of network card drivers and protocols
    can independently write code that communicates
    with NDIS
  • Acts as intermediary for all communication
    between protocol and network card driver

35
NDIS (continued)
  • Bindings between protocols and adapters are
    controlled by NDIS
  • A single adapter can be bounded to multiple
    protocols and visa-versa

36
TDI
  • Transport Driver Interface
  • Provides clients and services with access to
    network services
  • Emulates two network access methods
  • Network Basic Input/Output System (NetBIOS)
  • Windows Sockets (WinSock)
  • NetBIOS is the older network interface
  • WinSock is used by Internet Explorer, Outlook
    Express, and other internet applications

37
Activity 1-5 Research Networking Architecture
  • Objective Use Microsofts Help and Support to
    get additional information about NDIS and TDI
  • Find NDIS and TDI using the index within Help and
    Support

38
Common Network Services
  • Dynamic Host Configuration Protocol (DHCP)
  • Domain Name System (DNS)
  • Windows Internet Naming System (WINS)
  • Routing and Remote Access Service (RRAS)
  • Network Address Translation (NAT)

39
Common Network Services (continued)
  • Internet Connection Sharing (ICS)
  • Internet Authentication Service (IAS)
  • IP Security (IPSec)
  • Internet Connection Firewall (ICF)
  • Public key infrastructure (PKI)

40
Common Network Services (continued)
  • Network load balancing
  • Automated System Recovery
  • Internet Protocol version 6 (IPv6)
  • Point-to-Point Protocol over Ethernet (PPPoE)
  • Volume Shadow Copy

41
Activity 1-6 Viewing the Status of Services
Installed on a Windows Server 2003 Computer
  • Objective Identify installed network services
  • Check if the ICF service is running
  • Check what other services are running
  • Check out which services are enabled, automatic,
    started, or stopped

42
Activity 1-7 View Networking Services Available
for Installation
  • Objective View network services available for
    installation
  • Use Add/Remove Programs for this activity

43
Summary
  • Windows Server 2003 latest version of the
    Windows network OS with many new features
  • Four editions of Windows Server 2003 Web,
    Standard, Enterprise, and Datacenter Editions
  • Networks consist of two or more computers that
    share information
  • Information must be formatted using a network
    protocol before being sent on the network itself

44
Summary (continued)
  • OSI General network architecture model that
    describes how information is sent to and received
    from a network
  • TDI layer resides between clients and protocols
    or between services and protocols
  • NDIS is responsible for binding protocols to
    network adapters
  • Many network services are available in Windows
    Server 2003
