Introducing Windows Server 2003 Network
Architecture (continued)

• NDIS - Network Driver Interface Specification is
  a programming interface that resides between
  protocols and the adapter software
• TDI - Transport Driver Interface is a programming
  interface that resides between clients and
  protocols as well as between services and
  protocols

10
Windows Server 2003 Networking Architecture
(continued)
11
NDIS

• NDIS speeds the development of device drivers and
  enhances networking capabilities
• NDIS is an intermediary for all communication
  between the protocol and the network card driver
• When a protocol is configured to use an adapter,
  it is referred to as a binding
• Bindings between protocols and adapters are
  controlled by NDIS

12
TDI

• The TDI layer provides clients and services with
  access to network resources
• Applications talk to the TDI layer and the TDI
  layer passes on the requests to the protocols

13
Activity 1-2 Researching Networking Architecture

• Use the glossary in the Support section to read
  the different descriptions about NDIS and TDI
  layer

How Client Operating Systems Use Windows Server
2003 Services

• Windows Server 2003 provides a variety of
  different services such as
• SMB signing and secure channel encryption and
  signing are used by newer Windows clients
• The Active Directory client for Windows 9x and
  Windows NT adds the capability to access Active
  Directory features

31
Performing SMB Signing

• Server Message Block (SMB) is the protocol used
  by Windows Server to share files and printers
• All Windows Server 2003 domain controllers use
  SMB signing as a mechanism to ensure legitimate
  communication between clients and servers
• SMB signing places a digital signature on each
  packet this prevents the modification of packets
  in transit

32
Securing Channel Encryption and Signing

• Secure channels used for communication between
  Windows clients and servers that have a trust
  relationship
• Windows Server 2003 requires secure channels be
  encrypted or signed to ensure that communication
  is legitimate

33
Accessing Active Directory Features

• Features of the Active Directory client are
• Site Awareness
• Active Directory Service Interfaces
• Distributed File System
• NTLM version 2 Authentication
• Active Directory Searching

Planning a Windows Server 2003 Network
Infrastructure

• The success of any information technology project
  is based on good planning which must involve
• Choosing the members of the team
• Identifying the goals of the team
• Documenting the existing situation
• Defining objectives and tasks
• Testing the project
• Rolling out the project

38
The Team

• A project team has representatives from
• All areas of IT
• Affected business units
• At least one representative to liaise with upper
  management
• Each representative ensures interests of their
  own area are taken into account
• A defined project manager needs to be responsible
  for
• Ensuring resources to complete the project are
  available
• Ensuring the project is completed on time
• Liaising with other areas of the company to
  ensure that the project is supported

39
Goals

• Any IT project should begin with a set of
  business goals
• Goals should be clearly defined and obtainable
• When setting project goals try to avoid scope
  creep

40
Documentation

• When new network projects are implemented, a set
  of documentation is usually created as well
• To ensure that existing documentation is
  up-to-date, you can conduct
• Site surveys
• Interviews
• Research

41
Site Surveys

• A site survey is visiting a site to either create
  new documentation or confirm existing
  documentation

42
Interviews

• Useful to confirm the validity of existing
  documentation
• Can be done as part of a site survey

43
Research

• The easiest place to start researching components
  is by reading the manuals that came with them
• Most vendors offer documentation on their Web
  sites as well as additional support information
• Web-based discussion groups on the Internet can
  be helpful as long as you select reliable sources

44
Objectives and Tasks

• The objectives of a project are how the goals
  will be accomplished
• Tasks are how the objectives will be implemented
• The project team must decide how the objective
  will be attained based on issues such as risks,
  cost, and time to implement

45
Testing

• IT projects need to be properly tested in a lab
  environment before they are rolled out to users
• The test lab should be used to simulate all
  conceivable situations and factors that may
  affect the project
• Average users should be involved in the testing
  process since they use new software in ways that
  an experienced IT person would never dream of

46
Roll Out

• The roll out of an IT project is the actual
  implementation of new software and services
• Proper preparation for a roll out includes
  training for users and the help desk
• Everyone affected by the roll out, or potentially
  affected by the roll out, should be informed it
  is happening
• Most successful projects are phased in rather
  than being completed in one step

47
Activity 1-9 Researching Project Planning

• To ensure the success of your projects, in this
  exercise you perform further research into best
  practices for project planning
• Follow steps 1-6

48
Summary

• Windows Server 2003 is easy to install but
  default installations are different when compared
  to other releases of Windows operating systems
• The network architecture of Windows Server 2003
  is composed of four main networking components
  clients, services, protocols, and network
  adapters
• NDIS binds protocols to network adapters
• The TDI layer resides between clients and
  protocols or between services and protocols
• Four protocols are supported by Windows Server
  2003 IPv4, IPv6, IPX/SPX, and AppleTalk

49
Summary (continued)

• Windows Server 2003 installs a limited number of
  services by default
• When a server is promoted to be a domain
  controller, several network services are added
• Many network services are available in Windows
  Server 2003, including DHCP, DNS, WINS, RRAS,
  IAS, NAT, ICS, ICF, Insect, and PKI
• Four editions of Windows Server 2003 Web,
  Standard, Enterprise, Datacenter

50
Summary (continued)

• A successful Windows Server 2003 network
  infrastructure plan always takes into account the
  team, goals, testing, and roll out
• The team should contain representatives from all
  affected departments
• Goals should define what is done in the project
• Testing should be isolated from production
  network
• Roll out should minimize impact on existing
  network
