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

2. 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. 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 cluster size increased from four to eight nodes

4. 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. 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. 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 Itanium Processors

7. 7 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

8. 8 Hardware Requirements for Windows Server 2003, Web Edition

9. 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. 10 Hardware Requirements for Windows Server 2003, Standard Edition

11. 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 Services are supported –64-bit processing is supported

12. 12 Hardware Requirements

13. 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. 14 Hardware Requirements for Windows 2003,Datacenter Edition

15. 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. 16 Windows Server 2003 networking architecture

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

18. 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. 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. 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. 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. 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) –Certificates can be used to secure e-mail

23. 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. 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. 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. 26 Summary (Continued) Protocols supported –IPv4 –IPv6 –IPX/SPX –AppleTalk Network services available –DHCP, DNS, WINS –RRAS, IAS, NAT –ICS, ICF, IPSec, and PKI
