Transcript of Discuss clients, servers, and Windows network models

Discuss clients, servers, and Windows network models
Differentiate among the editions of Windows Server 2008
Identify Windows Server 2008 hardware requirements
Discuss the new Windows Server 2008 technologies
Describe the new roles and features in Windows Server 2008
Navigate the Windows Server 2008 interface


Windows Server 2008, Standard Edition
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


Windows Server 2008 Hardware Requirements
Microsoft provides minimum and recommended hardware requirements for installing its operating systems
Minimum requirements
Let you install and run a system using minimal resources and services

Clients, Servers, and Windows Network Models
Workgroup
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


INTRODUCTION TO
OBJECTIVES
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
Group Policy
A way to set up specific configurations for users and computers
within an Active Directory domain
Forest
A 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

Domain Model with Active Directory
General editions of Windows Server 2008
- Enterprise, Datacenter, and Standard
- Editions designed for special-purpose
server applications
Web Server and HPC Server

Features not available with 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

Windows Server 2008, Enterprise Edition
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


Windows Server 2008, Datacenter Edition
Server roles not available
- Dynamic Host Configuration Protocol (DHCP)
- DNS, file server
Does not require client access licenses (CAL) for users


Windows Web 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 HPC Server 2008
Centralizes commands to configuration tools
Allows you to easily manage your server and network

Server Manager
New Roles and Features in Windows Server 2008
Role
-Major function or service that a server performs
File Services role
-Allows the server to share files on a network
Server role
-Defines the specific task that a server is responsible for performing
Roles can be organized into three groups
-Active Directory
-Infrastructure
-Network roles




Active Directory Roles
Windows Server 2008 includes five Active Directory roles
Active Directory Certificate Services
Active Directory Domain Services
Active Directory Federation Services
Active Directory Lightweight Directory Services
Active Directory Rights Management Services

DHCP
-Network standard protocol used to dynamically allocate and
track IP addresses for clients on a network
DNS
-Main goal is to match a domain name to an IP address based
on a client query for information

Network Policy and Access Services (NPAS)
-Allows you to implement
Network Policy Server
Routing and Remote Access Service
Health Registration Authority
Host Credential Authorization Protocol


Network Roles
Active Directory roles that can be installed in Server 2008
Terminal Services
Fax Services
Print Services
File Services
Hyper-V
UDDI Services
Web Server (IIS 7)
Windows Deployment Services

Infrastructure Roles
New or improved features in Windows Server 2008
Start menu
Network and Sharing Center
Help and Support
Windows Desktop Experience

Windows Server 2008 User Interface
Windows Server 2008
- Incorporates the redesigned Start menu into its UI
Most efficient way to use the Windows Server 2008 Start menu
- Use the Start Search text box

Start Menu
Provides a central location for administering many network tasks in Windows Server 2008, including:
- Network connections
- Sharing settings
- Network discovery options


Network and Sharing Center
Most modern networks are based on client-server computing
Windows Server 2008 offers three general editions and two special-purpose editions
- Windows Server 2008 Standard
- Windows Server 2008 Enterprise
- Windows Server 2008 Datacenter
- Windows Web Server 2008
- Windows HPC Server 2008
Windows Server 2008
- Available for both 32-bit and 64-bit hardware architectures
New technologies in Windows Server 2008
- Focus on improving the performance, manageability, and security of networks
Windows Server 2008
- Lets you organize server services into roles and features
Server Manager
- Provides administrators with a GUI console for managing roles and features
Windows Server 2008
- Has a look and feel similar to Windows Vista

SUMMARY
ADVANTAGE
This makes a lot easier and manageable even the most basic scenario of file (and print) sharing, i.e. "we store files on a shared folder and we need to be able to choose who can access what", which can quickly become a pain in a workgroup environment, even with less than 10 users.
DISADVANTAGE
The main disadvantages are that you will need at least a server to act as the domain controller for the domain (but in a small business environment this can be done by a server also doing other things, like file sharing), that you will need to learn how to manage domains (which for basic management is not such a complex thing), and that you will need to take care of your domain controller, because not having it available will have a very bad impact on all domain computers (that's why usually at least two of them are used).
INTRODUCTION
Windows Server 2008, released on February 27, 2008, was originally known as Windows Server Codename "Longhorn". Windows Server 2008 builds on the technological and security advances first introduced with Windows Vista, and is significantly more modular than its predecessor, Windows Server 2003.
In Windows Server 2008, additional services were added to Active Directory, such as Active Directory Federation Services. The part of the directory in charge of management of domains, which was previously a core part of the operating system,[6] was renamed Active Directory Domain Services (ADDS) and became a server role like others. "Active Directory" became the umbrella title of a broader range of directory-based services. According to Bryon Hynes, everything related to identity was brought under Active Directory's banner.
