16. Introduction to Windows Server 2003 • Four different, but related NOSs: • Standard Edition • Web Edition • Enterprise Edition • Datacenter Edition

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

(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. 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. 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. 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. 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. 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. A Closer Look at Windows Server 2003 (continued)

25. A Closer Look at Windows Server 2003 (continued)

26. A Closer Look at Windows Server 2003 (continued) • Active Directory (cont.) • Organizational Units • NOSs use organizational units (OUs) to hold multiple objects that have similar characteristics • Windows Server 2003 OU can contain over 10 million objects

27. A Closer Look at Windows Server 2003 (continued)

28. A Closer Look at Windows Server 2003 (continued) • Trees and Forests • Domain tree • Root domain • Child domains • Forest • Collection of one or more domain trees
