Windows 2008 Overview

Lecture 1


Windows networking evolution

Windows Networking Evolution

  • Windows for Workgroups – peer-to-peer networking built into the OS

  • Windows NT – separate server and client versions, emphasis on client/server model, improved security, NTFS

  • Windows 2000 – improved interface, reliability and manageability, Active Directory

  • Windows 2003 – server only, “face-lift” -improved interface and management features

  • Windows 2008 – improved security, management features, reliability

  • Window 2012 – improved virtualization, security, new file system (ReFS)

  • Storage configuration

  • Performance and reliability

  • Security


Enhanced web services

Enhanced Web Services

  • Microsoft Internet Information Services (IIS)

    • Enhanced security

    • Easier application of patches

    • Easier for programmers to write and configure Web applications

    • Better management tools: IIS Manager


Windows server core

Windows Server Core

  • Minimum server configuration

  • Advantages:

    • No GUI overhead

    • Less disk space and memory needed

    • Smaller attack surface

  • Interact with server via command line


Windows powershell

Windows PowerShell

  • Command-line interface that offers a shell

  • Perform common administration tasks

  • Use cmdlets

    • 130 command line-tools

  • Scripting language


Virtualization

Virtualization

  • Hyper-V provides the ability to run two or more operating systems on a single computer

  • Capabilities:

    • Compatible with clustering

    • Able to handle up to a four-processor SMP computer

    • Can be used with Windows and Linux operating systems

    • Enables fast migration from one computer to another

    • Can house 64-bit and 32-bit operating


Reliability

Reliability

  • OS/Kernel runs in privileged mode

    • Core programs; computer code of operating system

    • Extra level of security

  • Protected processes

    • Computer program or portion of program

    • Protects premature interruption

  • Management features:

    • Server Manager

    • Wizards

    • Windows Reliability and Performance Monitor


Windows 2008 networking model

Windows 2008 Networking Model

  • Peer-to-peer networking (workgroup)

    • Spreads resource administration among server and nonserver members of network

    • Used by small businesses

  • Server-based networking (domain)

    • Centralizes network administration on servers

    • Used by medium and large networks


Peer to peer

Peer-to-Peer

  • Workgroup – logical grouping of network devices for resource sharing; peer-to-peer arrangement; decentralized

  • No special computer needed

  • Disadvantages:

    • Network management decentralized

    • Security is responsibility of each user

    • Less effective as number of workstations exceeds 10


Peer to peer networking workgroup model

Peer-to-Peer Networking- Workgroup model


Server based

Server-based

  • Domain– logical grouping of network devices for resource sharing; centralized

    • Single server can act as file and print server, Web server, network administration server, database server, e-mail server

    • Can handle many users at once

  • Advantages

    • Single log on

    • Stronger security

    • Sharing of files and resources

Server-based Networking Model


Protocols for the windows server 2008 networking model

Protocols for the Windows Server 2008 Networking Model

  • Protocol sets guidelines for:

    • Data formatting into packets and frames

    • Data transmission

    • Interpretation of packets and frames

  • Packets and frames

    • Units of data transmitted from a sending computer to a receiving computer


Protocols for the windows server 2008 networking model1

Protocols for the Windows Server 2008 Networking Model

  • Transmission Control Protocol/Internet Protocol (TCP/IP)

    • Suite of protocols and utilities that support communication across LANs and the Internet

  • Local area network (LAN)

    • Network of computers in relatively close proximity

  • TCP/IP used for several reasons


Internet protocol cont d

Internet Protocol (cont’d.)

  • IP addressing

    • Dotted decimal notation

    • 32 bits long

    • Four fields

    • Example: 129.5.10.100

  • Broadcast

    • Sends communication to all points on network

  • Subnet mask

    • Used to show class of addressing and to divide network into subnets


Internet protocol cont d1

Internet Protocol (cont’d.)

  • Static addressing

    • Assign permanent IP address

    • Gives consistency for monitoring

    • Can be laborious for large networks

  • Dynamic addressing

    • IP address assigned during logon

    • Uses the Dynamic Host Configuration Protocol (DHCP)


Internet protocol cont d2

Internet Protocol (cont’d.)

  • Default gateway

    • IP address of the router that has a connection to other networks

  • Name resolution

    • Domain Name System (DNS) translates domain and computer names to IP addresses

  • NetBIOS names

    • Windows Internet Naming Service (WINS) server resolves NetBIOS names to IP addresses

  • Host names

    • Dynamic Domain Name System (DDNS)


  • Login
