  1. Chapter 1 Windows Server 2003 Networking Overview

  2. 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

  3. 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 clustersize increased from four to eight nodes

  4. 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 (IPv6) • The future of Internet connectivity and will replace the current Internet Protocol version 4 (IPv4) • 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

  5. 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)

  6. 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 ItaniumProcessors

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

  8. Hardware Requirements for Windows Server 2003, Web Edition

  9. 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

  10. Hardware Requirements for Windows Server 2003, Standard Edition

  11. 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 Servicesare supported • 64-bit processing is supported

  12. Hardware Requirements

  13. 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

  14. Hardware Requirements for Windows 2003,Datacenter Edition

  15. 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

  16. Windows Server 2003 networking architecture

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

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

  19. Network Protocols • IPv4 • Normally referred to as TCP/IP • IPv6 • Newer version of TCP/IP that offers a number of enhancements • Internetwork Packet eXchange/Sequenced Packet eXchange (IPX/SPX) • Used primarily for backward compatibility with older networks running Novell Netware • AppleTalk • Used to communicate with Apple Macintosh computers

  20. 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 NetBIOS 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

  21. 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 IPv4 that creates secure IP-based communications

  22. 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) • Certificatescan be used to secure e-mail

  23. Summary • New Features of Windows Server 2003 • Enhanced Active Directory, .NET Framework, Web Services • IPv6, 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

  24. 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

  25. 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

  26. Summary (Continued) • Protocols supported • IPv4 • IPv6 • IPX/SPX • AppleTalk • Network services available • DHCP, DNS, WINS • RRAS, IAS, NAT • ICS, ICF, IPSec, and PKI
