Chuck Taylor http://home.hiwaay.net/~talorc/politics/concepts/progressive- tax.html Section III: Chapter Resources Chapter 1 Networking with Microsoft Windows 2000 Server Objectives After reading this chapter and completing the exercises you will be able to: „X Plan what network model to apply to your network „X Compare the differences between Windows 2000 Professional, Server, Advanced Server, and Datacenter „X Explain Windows 2000 capabilities as a server operating system „X Explain the new features in Windows 2000 „X Describe the file systems that are compatible with Windows 2000 and choose the file system that is right for your server Teaching Tips Planning a Networking Model 1. As you introduce students to networking concepts, provide several examples. For instance, discuss server NOSs such as Windows NT, Windows 2000, NetWare, UNIX, and others. Compare these to Workstation NOSs that include Windows 3.11, Windows 95, Windows 98, Windows 2000 Professional, UNIX, and others. 2. Consider having a class discussion about the general ways in which networks, servers, and workstations are used. Also, discuss how people rely on these information tools for everyday tasks. 3. When you discuss networks and the general ways in which they are used, briefly introduce the two networking models: peer-to-peer networking and server-based networking. Using Peer-to-Peer Networking 1. Provide students with examples of peer-to-peer networks and how they are used in small businesses and home office networks. Some examples from this author¡¦s experience include: „X An eight-person tax accounting office „X A five-person water-drilling firm „X A four-person investment group „X A five-person consulting office for mining operations „X A ten-person credit union 2. Consider supplementing your discussion of peer-to-peer networking with two or three network diagrams that illustrate the operating systems in use and how each workstation is used. 3. Review the advantages and disadvantages of strict peer-to-peer networks and have students suggest additional advantages and disadvantages from their own experience. 4. Compare using Windows 3.11, Windows 95, Windows 98, and Windows NT/2000 in a peer-to-peer networking context. Using Server-based Networking 1. Provide students with examples of server-based networks in action. Several examples from this author¡¦s experience include: „X Medium and large company installations for a variety of implementations that include financials, human resources, payroll, marketing/sales, inventory, manufacturing, distribution systems, research systems, project management, engineering and CAD applications, fund raising systems, time clock systems, vacation and sick leave systems, mail subscription offers and promotions, and more „X Small, medium, and large colleges and universities for all types of functions that include student labs, academic computing, engineering, administrative systems, student systems, foundation and alumni development systems, budgeting, time clock systems, athletic department systems, facilities management, and more „X Client/server and database systems „X Web and multimedia installations „X E-commerce and e-mail systems „X Backup and utility systems „X Providing multimedia presentations on commercial airlines and in hotels 2. Present to students two or three network diagrams illustrating how server-based systems are used in different kinds of organizations. 3. Review the advantages and disadvantages of server-based systems and compare them to peer-to-peer networks. Also, discuss hybrid networks that offer a combination of peer-to-peer and server-based information access. 4. To illustrate the kind of power available through server-based networking, mention that early tests of Windows 2000 Server in a multiple node configuration have set a new benchmark for the maximum number of transactions processed in a minute: over 227,000 transactions. Windows 2000 Server and Windows 2000 Professional Compared 1. Make sure that students understand the differences between Windows 2000 Server and Windows 2000 Professional, particularly in terms of: numbers of clients that can be handled, advanced networking features, network management tools, storage management, remote access capabilities, software application and printer management, and versatility. 2. Consider performing your own experiment in class or in a lab to illustrate the client load that Windows 2000 Server will tolerate compared to the load tolerated by Windows 2000 Professional. 3. Contact the IT department in your school and find out their estimated TCO for supporting workstations on a network. Another option is to have a representative from your school¡¦s or a local business¡¦ IT department visit class to discuss the factors that influence workstation costs, as well as the actual TCO of workstations. 4. Discuss with students different scenarios in which they might need to use a multi-processor computer, such as a two-processor workstation or a four-processor server. 5. Discuss situations in which Windows 2000 Professional is needed instead of Windows 98 for a workstation¡¦s operating system. 6. In general terms, discuss how Windows 2000 Professional can be installed and configured via a Windows 2000 server. Have students explore how this can be an advantage in terms of: „X User support „X Applications support „X Printing support „X Security 7. Consider presenting an evolution of Windows NT to Windows 2000. The following table illustrates milestones in the evolutionary process. Date Windows NT/2000 Release Late 1991 First release of Windows NT to a small group of developers Mid 1992 Release of Windows NT to a large group of developers Fall 1992 First Windows NT beta version release Early 1993 Second Windows NT beta version release Mid 1993 Released to the public as Windows NT version 3.1 Mid 1994 Networking and remote access improvements, greater speed, better connectivity to other server operating systems in Windows NT version 3.5 Mid 1995 More device support and the ability to install Windows 95 and Windows NT to workstations via the network in Windows NT version 3.51 Mid 1996 Implementation of new desktop interface, enhanced networking, Internet, introduction of directory services, and installation features in Windows NT version 4.0 Late 1998 More drivers, enhanced Web and multimedia support, and enhanced multiprocessor support (and new enterprise software options) introduced in Windows NT 4.0 service packs 1 through 4. Late 1998 While still under development, Windows NT 5.0 is renamed Windows 2000 to correspond with naming changes for other Microsoft software products Early 2000 Windows 2000 is released to include the Active Directory, new management tools, new storage and backup capabilities, more drivers, and an enhanced version of the network file system (NTFS) Windows 2000 Server, Advanced Server, and Datacenter Compared 1. Discuss with students situations in which they might need to use multiprocessor servers, particularly for Web, client/server, multimedia, and other implementations. Also, link these situations to using Windows 2000 Server, Advanced Server, or Datacenter. 2. Make sure that students understand server clustering and the situations in which it might be used. Provide students with illustrations from your school campus or a nearby business. Also, consider supplementing your discussion with one or two network diagrams showing how clustering is implemented. Windows 2000 Server Capabilities 1. Consider introducing the Windows 2000 Server capabilities by discussing their history and evolution since they were first conceived in 1988 for the Windows NT operating system. Also, discuss how the quick rise of the Internet has influenced the capabilities of Windows 2000 in terms of Web, Internet, intranet, VPN, e-mail, and e-commerce options. The following table illustrates the first goals that were proposed for Windows NT, over a decade ago. Goal Today¡¦s Implementation Reliability, to support demanding business applications such as database operations Programs cannot interfere with the operating system or with other programs, making the system more crash proof Security, to meet government specifications and to satisfy business auditing requirements Compatible with the requirements for government C2 security which includes security levels up to top secret Scalability, the option to scale the system to larger computers, including those with multiprocessing architectures Runs on Pentium, Pentium Pro, Pentium II, Pentium III, Xeon, and multiprocessor systems Extensibility, with protected links into the operating system to accommodate a wide range of hardware drivers and be extended for networking, electronic mail, and other purposes. Uses drivers, application programming interfaces, and other methods to enable extended capabilities for hardware and software development Portability, through a system kernel that can be ported to computers. Program kernel is written for portability to a growing number of hardware platforms Compatibility, with the many MS-DOS and Windows programs already implemented Not as compatible as Windows 95 and Windows 98 with older DOS programs due to the 32-bit architecture and security requirements, but it is compatible with Windows-based programs and DOS programs that do not directly access hardware Distributability, for applications used on a network Extensively network compatible with network communication protocols, remote access services, and Internet/intranet/extranet services, distributed file system, and high-speed networking Government Certification, to meet demanding Federal Government standards Conforms to open systems and security requirements of the Federal Government Sharing Resources 1. Discuss in class the costs of using individual resources for each workstation compared to the ability to share resources through a server. Include the following elements in your discussion: „X Software „X Printers „X Fax equipment „X Disk storage „X Data storage „X User productivity „X Support „X Training 2. Compare and contrast the merits of enabling users to store files on a server versus purchasing individual disk storage for each user. In your discussion, you might introduce the idea of thin clients and how they can use Windows 2000 terminal services to run applications and store information at a server.
