Hands-On Microsoft Windows Server 2003 Networking Chapter 1 Windows Server 2003 Networking Overview

Objectives • Describe some of the new features of Windows Server 2003 • Understand the differences in the editions of Windows Server 2003 • Recognize the components in the Windows Server 2003 networking architecture • List the networking services available in Windows Server 2003 2

New Features of Windows 2003 • Enhanced Active Directory – Now more flexible, manageable, and reliable • . NET Framework – Allows programmers develop applications in a variety of languages, such as C++, C#, or Visual Basic • Web services – Native support for XML Web services is included • Enhanced clustering and load balancing – Maximum cluster size increased from four to eight nodes 3

New Features of Windows 2003 (Continued) • Automated system recovery – Allows single step recovery of operating system • Internet Information Server (IIS) 6. 0 – Default configuration locked down to be more secure • Internet Protocol version 6 (IPv 6) – The future of Internet connectivity and will replace the current Internet Protocol version 4 (IPv 4) • Point-to-Point Protocol Over Ethernet (PPPOE) Enhanced IP Security (IPSec) – Used by many high-speed Internet service providers (ISPs) to control traffic on their networks 4

New Features of Windows 2003 (Continued) • Network bridging – In smaller networks, Windows Server 2003 can be used as a bridge • Wireless support – Includes extensions to Group Policy and a Microsoft Management Console (MMC) snap in • Enhanced IP Security (IPSec) – Allows transmission of encrypted packets through network address translation (NAT) 5

New Features of Windows 2003 (Continued) • Internet Connection Firewall (ICF) – Basic firewall protection provided for small businesses • Volume Shadow Copy – Allows files to be backed up when they are open • Windows Media Services – Can provide streaming audio and video • 64 -bit support – Support for 64 -bit processing on Intel Itanium Processors 6

Web Edition • A lower-cost version of Windows Server 2003 that is optimized to be a dedicated Web server • Meant to counter Linux in the market for utility servers • Some unique features – Must be a member server or stand-alone server – Load balancing is supported – Clustering is not supported – VPN support is limited – Services for Macintosh are not supported 7

Hardware Requirements for Windows Server 2003, Web Edition 8

Standard Edition • The version most likely to be used as a departmental file and print server or application server • Some unique features – Can be a domain controller, member server, or stand-alone server – Load balancing is supported – Clustering is not supported – Full VPN support is available – Services for Macintosh are supported 9

Hardware Requirements for Windows Server 2003, Standard Edition 10

Enterprise Edition • Designed to enable large enterprises to deliver highly available applications and Web services • Some unique features – Can be a member server, domain controller, or stand-alone server – Load balancing is supported – Clustering is supported – Metadirectory Services are supported – 64 -bit processing is supported 11

Hardware Requirements 12

Datacenter Edition • Designed for mission-critical applications that require the highest levels of availability and scalability • Some unique features – Can be a member server, domain controller, or stand-alone server – Load balancing is supported – Clustering is supported – Metadirectory Services are not supported – 64 -bit processing is supported 13

Hardware Requirements for Windows 2003, Datacenter Edition 14

Windows Server 2003 Network Architecture • Four major components in networking – Client: makes requests for resources on the network – Service: responds to requests from client software and provides access to resources – Protocol: used by client and service software to communicate – Adapter: driver for the network card 15

Windows Server 2003 networking architecture 16

Network Device Interface Specification (NDIS) • A specification created by Microsoft and 3 Com to speed the development of device drivers and enhance networking capabilities • Bindings between protocols and adapters controlled by NDIS 17

Transport Device Interface (TDI) • Provides clients and services with access to network resources • Emulates two network access mechanisms: – Network Basic Input Output System (Net. BIOS) – Windows Sockets (Win. Sock) • Windows Sockets Direct (Win. Sock Direct) – New enhancement to Win. Sock that is used to access resources on system area networks 18

Network Protocols • IPv 4 – Normally referred to as TCP/IP • IPv 6 – Newer version of TCP/IP that offers a number of enhancements • Internetwork Packet e. Xchange/Sequenced Packet e. Xchange (IPX/SPX) – Used primarily for backward compatibility with older networks running Novell Netware • Apple. Talk – Used to communicate with Apple Macintosh computers 19

Networking Services • Dynamic Host Configuration Protocol (DHCP) – Automated mechanism used to assign IP addresses to client computers • Domain Name System (DNS) – Converts host names to IP addresses • Windows Internet Naming Service (WINS) – Converts Net. BIOS names to IP addresses • Routing and Remote Access Service (RRAS) – Allows Windows Server 2003 to act as a router, VPN server, and dial-in server 20

Networking Services (Continued) • Internet Connection Sharing (ICS) – Automated way to set up DHCP, NAT, and a DNS proxy for small networks • Internet Authentication Service (IAS) – Allows a company to use Active Directory for centralized authentication of remote access clients • IP Security (IPSec) – Enhancement to IPv 4 that creates secure IPbased communications 21

Networking Services (Continued) • Internet Connection Firewall (ICF) – Suitable for small businesses using Windows Server 2003 as the router connecting to their ISP • Public Key Infrastructure (PKI) – Certificates can be used to secure e-mail 22

Summary • New Features of Windows Server 2003 – Enhanced Active Directory, . NET Framework, Web Services – IPv 6, Network bridging – PPPOE support, Built-in wireless support – Internet Connection Firewall, 64 -bit support • Web Edition – Designed to be Web server only – Cannot be a domain controller 23

Summary (Continued) • Standard Edition – Designed to be a departmental server – Can be configured as domain controller – Does not support clustering – Not available in 64 -bit version Enterprise Edition – Supports up to eight clusters • Datacenter Edition – Designed for mission-critical applications – Minimum eight processors required – Up to 32 processors supported 24

Summary (Continued) • Network architecture – Clients – Services – Protocols – Network adapters • Interfaces – TDI: resides between clients and protocols or between services and protocols – NDIS: responsible for binding protocols to network adapters 25

Summary (Continued) • Protocols supported – IPv 4 – IPv 6 – IPX/SPX – Apple. Talk • Network services available – DHCP, DNS, WINS – RRAS, IAS, NAT – ICS, ICF, IPSec, and PKI 26
