  10. (Skill 3) Overview of Windows Server 2003 Operating System Architecture • Modular structure with each module contributing specific functionality • Basically the same for Standard, Enterprise, Datacenter, and Web Editions • Two primary layers • User mode • Kernel mode

  11. (Skill 3) Overview of Windows Server 2003 Operating System Architecture (2) User mode layer • Consists of a set of components known as subsystems, responsible for relaying input/output requests to the appropriate kernel mode driver through the Input/Output (I/O) system services • Environmental subsystems provide APIs • Integral subsystems • Perform various functions such as the creation of security tokens and monitoring user rights and permissions • Run in user mode, but perform essential operating system functions

  12. (Skill 3) Overview of Windows Server 2003 Operating System Architecture (3) Kernel mode layer • Operates in a protected area of memory • Provides services to user mode subsystems, which functionally protects and isolates the hardware from the software

  13. (Skill 3) Figure 1-6 User mode and kernel mode layers

  16. (Skill 3) Overview of Windows Server 2003 Operating System Architecture (6) • Microkernel • Core of the operating system • Manages the computer’s processors • Handles scheduling, interrupts, exception dispatching, and CPU synchronization • Hardware Abstraction Layer (HAL) • Hides the hardware interface details from the end user by acting as an interface between the user and the hardware devices • Handles I/O interfaces, interrupt controls, and multiprocessor communication mechanisms

  17. (Skill 3) Overview of Windows Server 2003 Operating System Architecture (7) • Kernel mode drivers • Translate I/O requests into hardware functions • Are modular components each with a well-defined and specific set of functionality requirements • Three main classifications • Lowest-level drivers control peripheral devices • Intermediate drivers are device type-specific • Highest-level drivers are file system drivers

  19. (Skill 3) Figure 1-8 Classifications of kernel mode drivers

  20. (Skill 4) Introducing Workgroup and Domains • Windows Server 2003 operating system supports workgroups and domains, the two basic network model types that enable users to share common resources • A workgroup or peer-to-peer network is a logical group of computers that are interconnected, generally over a local area network (LAN) • A domain is a logical grouping of network computers that share a central directory database

  21. (Skill 4) Introducing Workgroup and Domains (2) • Workgroup features • The administration of user accounts and resource security in a workgroup is decentralized • To gain access to resources on any computer in the workgroup, user must have an account on that computer • Workgroup limitations • A workgroup model is practical only in smaller environments where computers are in close proximity • Microsoft recommends that a workgroup consist of less than 10 computers

  22. (Skill 4) Figure 1-9 Workgroup model

  23. (Skill 4) Introducing Workgroup and Domains (3) • Domain features • Active Directory database • Stores information about how the network is structured and organized • Enables users to identify and locate resources on the network • Domain controller • Windows Server 2003 computer on which Active Directory resides • Manages security-related aspects of user/domain interactions

  24. (Skill 4) Introducing Workgroup and Domains (4) • Domain advantages • Centralized security and administration means that a change to any object within the domain is available to the entire domain • Provide a single logon process for users to gain access to network resources, such as file, print, and application resources

  25. (Skill 4) Figure 1-10 Domain model

  26. (Skill 5) Introducing Network Services in Windows Server 2003 • Dynamic Host Configuration Protocol (DHCP) • Domain Name System (DNS) • Windows Internet Name Service (WINS) • Virtual Private Networks (VPN) • Routing and Remote Access Service (RRAS) • Internet Authentication Service (IAS) and Load Balancing • Internet Connection Firewall (ICF)

  27. (Skill 5) Introducing Network Services in Windows Server 2003 (2) • Dynamic Host Configuration Protocol (DHCP) • Provides the standard used by DHCP servers on the network • DHCP servers manage the dynamic allocation of IP addresses and the related configuration details for DHCP-enabled clients on your network • Domain Name System (DNS) • Main name resolution service for Windows Server 2003 • Enables access to computers on a TCP/IP network using the domain name

  28. (Skill 5) Introducing Network Services in Windows Server 2003 (3) • Windows Internet Name Service (WINS) • Assigns or maps an IP address to a computer name so network users can find a computer on a TCP/IP network using the NetBIOS name • WINS server database provides a lookup directory • Virtual Private Networks (VPNs) • Provide connections to private networks, such as a LAN, through a non-secure communication channel like the Internet • Use tunneling and encryption to create a virtual tunnel for secure information exchange

  29. (Skill 5) Introducing Network Services in Windows Server 2003 (4) • Routing and Remote Access Service (RRAS) • Allows remote or mobile workers to connect to a firm’s networks so that they can work as if their computers were physically connected to the network • Workers connect to the LAN via modem or Virtual Private Network (VPN) • IAS RADIUS and Load Balancing • Internet Authentication Service (IAS) is Windows Server 2003’s Remote Authentication Dial-In User Service (RADIUS) server component • Network Load Balancing (NLB) allows certain types of servers (mostly file/print servers and Web servers) to scale to a much larger size than would otherwise be possible

  30. (Skill 5) Introducing Network Services in Windows Server 2003 (5) • IAS Enhancements • Centralize services for wireless users and logs information to a Microsoft SQL server • Allow advanced SQL queries • Provides new 801.1X authentication features and cross-forest authentication • Internet Connection Firewall (ICF) • Supplies basic protection on computers directly connected to the Internet or on LAN segments • Designed for use in a small business

  35. (Skill 6) Introducing Network Protocols (2) • Transmission Control Protocol/Internet Protocol (TCP/IP) • Core protocol suite used by the Internet and Windows 2003 Server networks • Scalable and routable transport protocol suite used for both large and small networks • Enables you to route messages across networks and between computers using different operating systems and with widely varying structural designs

  36. (Skill 6) Introducing Network Protocols (3) • Point-to-Point Tunneling Protocol (PPTP) • Tunneling protocol used to create secure connections to corporate networks, over any intermediate network • Secure connections for VPNs are created using either PPTP or Layer Two Tunneling Protocol • Layer Two Tunneling Protocol (L2TP) • Another tunneling protocol used to create VPNs • Creates a “tunnel” but does not encrypt data • Use in conjunction with IPSec, which provides data encryption

  37. (Skill 6) Introducing Network Protocols (4) • Hypertext Transmission Protocol (HTTP) • Part of the TCP/IP protocol suite • Standard protocol used in the transmission of data across the Internet

  41. (Skill 7) Introducing Network Security Services (3) • Internet Protocol Security (IPSec) • A vendor-independent encryption protocol • The ability to sign and/or encrypt any IP packet makes it vendor- and application-independent • Encrypting File System (EFS) • Encrypts data stored in files and folders to protect against unauthorized access • In the EFS encryption technique, important data is secured using an asymmetrical cryptographic key pair: a public key and a private key
