  • 1. Chapter 8: Network Operating Systems and Windows Server 2003-Based Networking Network+ Guide to Networks
  • 2. 2 Objectives: Discuss the functions and features of a network operating system Define the requirements for a Windows Server 2003 network environment Describe how Windows Server 2003 fits into an enterprise-wide network
  • 3. 3 Objectives (continued) Perform a simple Windows Server 2003 installation Manage simple user, group, and rights parameters in Windows Server 2003 Understand how Windows Server 2003 integrates with other popular network operating systems
  • 4. 4 Introduction to Network Operating Systems • Centrally manage network resources • Secure access to network • Allow remote users to connect • Allow users to connect to other networks • Back up data and make sure it’s available • Allow for simple additions of clients and resources • Monitor status and functionality of network elements • Distribute programs and software updates to clients • Ensure efficient use of a server’s capabilities • Provide fault tolerance
  • 5. 5 Introduction to Network Operating Systems (continued) • Selecting a Network Operating System • Compatible with existing infrastructure? • Provide the security required by resources? • Can technical staff manage it effectively? • Will applications run smoothly on it?
  • 6. 6 Introduction to Network Operating Systems (continued) • Selecting a Network Operating System • Will it accommodate future growth? • Does it support the additional services users require? • Does it fit budget? • What additional training will it require? • Support from its manufacturer?
  • 7. 7 Introduction to Network Operating Systems (continued) • Network Operating Systems and Servers • How many clients will connect to the server? • What kinds of applications will run on the server? • How much storage space will each user need? • How much downtime, if any, is acceptable? • What can the organization afford?
  • 8. 8 Network Operating System Services and Features • Client Support • Creating and managing client accounts • Enabling clients to connect to the network • Allowing clients to share resources • Managing clients’ access to shared resources • Facilitating communication between clients
  • 9. 9 Network Operating System Services and Features (continued) • Client/Server Communication • Credentials- user name and password • Redirector- intercepts the request • Authentication- matching credentials
  • 10. 10 Network Operating System Services and Features (continued) • Users and Groups • Access a client (or user) has depends on user account and groups assigned
  • 11. 11 Network Operating System Services and Features (continued) • Identifying and Organizing Network Elements • Directory • LDAP (Lightweight Directory Access Protocol) • Object • Attributes • Schema • Containers, or Organizational Units (OUs).
  • 12. 12 Network Operating System Services and Features (continued) • Sharing Applications • Ability to share resources, reducing costs and time required to manage the resources • Sharing Printers • Increase the efficiency of managing resources and reduce costs for an organization
  • 13. 13 Network Operating System Services and Features (continued) • Sharing Printers • All NOSs can • Create an object that identifies the printer to the rest of the network • Assign the printer a unique name • Install drivers associated with the printer • Set printer attributes, such as location and printing preferences
  • 14. 14 Network Operating System Services and Features (continued) • Sharing Printers • All NOSs can (continued) • Establish or limit access to the printer • Remotely test and monitor printer functionality • Update and maintain printer drivers • Manage print jobs, including modifying a job’s priority or deleting jobs from the queue
  • 15. 15 Network Operating System Services and Features (continued) • Managing System Resources • Memory • Physical memory and Virtual memory • Multitasking • Preemptive multitasking • Multiprocessing • Processing and Threads
  • 16. 16 Introduction to Windows Server 2003 • Four different, but related NOSs: • Standard Edition • Web Edition • Enterprise Edition • Datacenter Edition
  • 17. 17 Why Choose Windows Server 2003? • General benefits, Standard Edition • Support for multiple processors, multitasking, and symmetric multiprocessing • Active Directory • Microsoft Management Console (MMC) • Integrated Web development and delivery services • Support for modern protocols and security
  • 18. 18 Why Choose Windows Server 2003? (continued) • General benefits, Standard Edition • Excellent integration with NOSs and support for client operating systems • Integrated remote client services • Provisions for monitoring and improving server performance • Support for high-performance, large-scale storage devices
  • 19. 19 Windows Server 2003 Hardware Requirements • Servers generally require more processing power, memory, and hard disk space than do client workstations • The Hardware Compatibility List (HCL) lists all computer components proven to be compatible with Windows Server 2003.
  • 20. 20 A Closer Look at Windows Server 2003 • Windows Server 2003 Memory Model • Can use virtual memory • Assigns each application (or process) its own 32- bit memory area • Allows you to install more physical memory
  • 21. 21 A Closer Look at Windows Server 2003 (continued) • Windows Server 2003 File Systems • FAT (File Allocation Table) • FAT16 & FAT32 • CDFS (CD-ROM File System) and UDF (Universal Disk Format) • NTFS (New Technology File System)
  • 22. 22 A Closer Look at Windows Server 2003 (continued) • Microsoft Management Console (MMC) • All administrative tools are integrated into a single interface • Purpose is to gather multiple administrative tools into a convenient console for your network environment
  • 23. 23 A Closer Look at Windows Server 2003 (continued) • Active Directory • Workgroups • Group of interconnected computers that share each other’s resources • Domains • Domain model • Domain controllers • Member servers.
  • 24. 24 A Closer Look at Windows Server 2003 (continued)
