clients servers and windows network models
Clients, Servers, and Windows Network Models
  • Client/Server Computing (Domain model with Active Directory)
  • Peer-to-peer (Workgroup model)
    • Network of computers that allow each other access to their files, printers, or Internet connection
  • By default, all Windows Server 2008 computers are placed in a workgroup named WORKGROUP
  • Membership status
    • Either a single workgroup or a domain
domain model with active directory
Domain Model with Active Directory
  • Domain
    • Group of users and computers managed by the same security database
  • Active Directory Domain Services (AD DS)
    • Technology that runs the domain security database
  • Domain controllers (DCs)
    • Servers that hosts domain security database
  • Domain Name System (DNS)
    • TCP/IP-based standard for resolving computer names with IP addresses
domain model with active directory continued
Domain Model with Active Directory (continued)
  • Group Policy
    • A way to set up specific configurations for users and computers within an Active Directory domain
  • Forest
    • Network of domains related to each other by relationships known as trusts
  • Transitive trusts
    • Trusts between Active Directory domains in a tree are created automatically when you create domains
      • Allows sharing resources and information
windows server 2008 standard edition se
Windows Server 2008, Standard Edition (SE)
  • Designed for smaller environments and single-purpose installations
  • Works as a single domain server for a small business or
    • A single file/application server in larger environments
  • File and Print Services
  • Internet Information Services (IIS) 7
  • Active Directory
  • Distributed and Encrypting File Systems
  • Various management tools
  • Network Load Balancing
windows server 2008 enterprise edition ee
Windows Server 2008, Enterprise Edition (EE)
  • Features not available with Standard Edition (SE)
    • Significant increase in maximum allowable memory
    • Active Directory Federation Services (discussed later in this chapter)
    • Failover clustering
    • Installation of up to four virtual machines on each physical host
    • Hot-add memory
  • Decision to use Enterprise edition versus Standard edition depends on expense and functionality
windows server 2008 datacenter edition de
Windows Server 2008, Datacenter Edition (DE)
  • Additional features
    • Ability to run up to 32 processors
    • Ability to hot-add and replace processors
    • Installation of unlimited virtual machines on each physical host
    • Each processor installed needs a Datacenter license
      • Microsoft does not currently differentiate among single, dual, and quad-core processors for licensing. All are considered a single processor.
windows web server 2008
Windows Web Server 2008
  • Server roles not available
    • Dynamic Host Configuration Protocol (DHCP)
    • DNS, file server
  • Purpose of this server is hosting Web sites and applications
  • Does not require client access licenses (CAL) for users
    • Software licenses that allow clients to access resources on a Microsoft network
  • You may install databases without limitations on user access to the Web site and its related data
windows hpc server 2008
Windows HPC Server 2008

Designed for High-Performance Computing (HPC) applications

Accommodates up to thousands of processing cores because it is built on the Server 2008 64-bit architecture model

windows server 2008 without hyper v
Windows Server 2008, Without Hyper-V
  • Hyper-V
    • Consolidates multiple server roles as separate virtual machines running on a single physical machine
    • Lets you efficiently run different operating systems in parallel on a single server
    • 32-bit versions of SE, EE, and DE do not support Hyper V
windows server 2008 for itanium based systems
Windows Server 2008 for Itanium-Based Systems
  • Standard, Enterprise, and Datacenter editions
    • Available for servers using Intel Itanium Processors
  • Itanium processors
    • Use a different architecture from other 32-bit and 64-bit processors
32 bit and 64 bit processors
32-Bit and 64-Bit Processors
  • Differences between 32-bit and 64-bit processors are in:
    • Hardware limits
    • Driver and application support
  • 64-bit architectures
    • Have greater theoretical limit for processing data
    • Can handle twice the amount of data of a comparable 32-bit product
    • Windows Server 2008 64-bit version cannot run 16-bit Windows applications or use 32-bit drivers
      • You cannot run some legacy applications and hardware with 64-bit version
      • For legacy applications, virtual technologies are excellent option
new technologies in windows server 2008
New Technologies in Windows Server 2008
  • Enhancements include:
    • Improved installation process
    • Hyper-V
    • Server Core
    • TCP/IP improvements
    • Network Access Protection
    • Server Manager
    • Windows Remote Management
    • PowerShell
    • Group Policy preferences
improved installation process
Improved Installation Process
  • Requires minimal user input
  • You no longer have to wait for the installation program to ask for information
    • Networking information, regional settings, and other settings
hyper v
Hyper-V
  • Virtualization
    • Allows you to run one or more separate instances of an OS within a single host OS (conserves hardware resources)
    • Allows organizations to consolidate these physical systems onto high-powered servers (known as host system)
    • Available in 64-bit editions of Windows Server 2008 or as add-on application
server core
Server Core
  • Stripped-down installation of Windows Server 2008 with a set of available roles and services more limited than in the Full version
  • Attack surface
    • Areas of the system that could expose it to security breaches
  • Much of UI removed
  • Provides single command-line window and tools for administration
  • Can be installed on Standard, Enterprise, and Datacenter editions of Windows Server 2008
    • But only during initial installation of the operating system
    • Cannot upgrade from Server Core to Full version unless you perform a complete operating system reinstallation
network access protection nap
Network Access Protection (NAP)
  • Helps to protect networks, both public and private, from malware such as viruses and spyware
  • Threat sources
    • Employees accessing the Internet from work and inadvertently install Trojan horses
    • Remote access to connections from external networks that create a gateway for viruses
    • Guest computers accessing an internal network that introduce malware to the network
tcp ip improvements
TCP/IP Improvements
  • Next-Generation TCP/IP stack
    • New implementation of the TCP/IP protocol stack
    • Contains full support for IPv4 and IPv6
  • Teredo
    • IPv6 technology that can encapsulate IPv6 packets as IPv4 packets to allow them to traverse IPv4 networks
  • Receive Window Auto-tuning
    • Optimizes the size of data packets a server can accept
server manager
Server Manager

Centralizes commands to configuration tools

Allows you to easily manage your server and network

powershell

Becoming de facto CLI and scripting language for Microsoft products

Allows you to string together commands, passing the result of one command into the next, in a process known as pipelining

Passes results as .NET objects (not as text)

windows remote management winrm
Windows Remote Management (WinRM)
  • Administrators can manage servers remotely by running management scripts and managing data on remote machines
  • WinRM allows you to access, edit, and update data from local and remote computers
  • WS-Management protocol
    • Public standard for exchanging management data remotely by any device implementing the protocol
group policy preferences
Group Policy Preferences

New feature of the Group Policy Management Console (GPMC)

Applied but not enforced, settings in Group Policy enforced, preventing users from making changes

Helps to implement Group Policies within your Active Directory environments
