Overview of Windows Server 2003 Operating System
Architecture
(Skill 3)
  • 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
Overview of Windows Server 2003 Operating System
Architecture (2)
(Skill 3)
  • 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
Overview of Windows Server 2003 Operating System
Architecture (3)
(Skill 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)

Architecture (4)
(Skill 3)
  • Kernel mode layer components
  • Executive
  • Microkernel
  • Hardware Abstraction Layer (HAL)
  • Set of kernel mode drivers
  • Executive Services are responsible for performing
    I/O requests and object management

15
Overview of Windows Server 2003 Operating System
Architecture (5)
(Skill 3)
  • Executive Services key components

16
Overview of Windows Server 2003 Operating System
Architecture (6)
(Skill 3)
  • Microkernel
  • Core of the operating system
  • Manages the computers 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
Overview of Windows Server 2003 Operating System
Architecture (7)
(Skill 3)
  • 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

Introducing Workgroup and Domains
(Skill 4)
  • 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
Introducing Workgroup and Domains (2)
(Skill 4)
  • 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
Introducing Workgroup and Domains (3)
(Skill 4)
  • 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
Introducing Workgroup and Domains (4)
(Skill 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

    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
Introducing Network Services in Windows Server
2003 (3)
(Skill 5)
  • 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
Introducing Network Services in Windows Server
2003 (4)
(Skill 5)
  • Routing and Remote Access Service (RRAS)
  • Allows remote or mobile workers to connect to a
    firms 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 2003s 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

  • 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
