Objectives

• Understand networking in Windows XP
• Understand Windows XP networking protocols
• Configure and use TCP/IP protocols and services
• Access NetWare servers and services from Windows
  XP
• Understand Windows XP Remote tools

3
Understanding Protocols

• A Protocol Is an Agreed Upon Way to Communicate
• Diplomatic Protocol
• Chevy Nova
• Cultural Clashes
• Failure to Observe Protocol Results In Failure to
  Communicate

4
Many Protocols Many UsesNetworking

• TCP/IP De Facto Internet Protocol Suite
• IPX/SPX Protocol Suite Used By Netware 3.x and
  .x (Netware 5, Is TCP/IP)
• NetBEUI Default Small Microsoft Network
  Protocol (Non-Routable)

5
Many Protocols Many UsesMail

• LDAP Lightweight Directory Access Protocol Used
  To Look Up Names Of Individuals On The Internet
  Such As 4-1-1 And Others. Also By Win 2K Active
  Directory
• SMTP Send e-Mail To The Internet
• POP Receive e-Mail From The Internet

Many Protocols Many UsesSome Others

• FTP File Transfer Protocol
• TFTP Trivial FTP, Used By Most Routers
• DLC Used By HP Printers To Share A Network
  Printer, Also IBM Host Session
• SNMP Used For Workstation Diagnosis And
  Identification
• DHCP Dynamic Host Control Protocol
• Many Others

Configuring TCP/IP To Use A Static Address

• By Default, Client Computers Running Microsoft
  Windows 2000, Microsoft Windows 98, Or Microsoft
  Windows 95 Obtain TCP/IP Configuration
  Information Automatically.
• Some Computers Should Always Be Assigned A Static
  Ip Address, For Example The Computer Running The
  Dhcp Service.

11
Options Used In Configuring A Static TCP/IP
Address

Using Automatic Private IP Addressing

• Extension Of Dynamic IP Address Assignment For
  LAN Adapters
• Enables Configuration Of IP Addresses Without
• Using Static IP Address Assignment
• Installing The DHCP Service
• Configure Network LAN Adapter To Obtain An IP
  Address Automatically

14
Steps In Automatic Private IP Addressing
15
Using TCP/IP Utilities
16
Testing a TCP/IP Configuration
17
Using Ipconfig

• Use Ipconfig /All To Verify The TCP/IP
  Configuration Parameters On A Host Using DHCP.
• Use Ipconfig /All More To Prevent The Ipconfig
  Output From Scrolling Off The Screen.

18
Example 1, Understanding Ipconfig /All

• If The Configuration Is Initialized
• Ipconfig Displays The IP Address And Subnet Mask.
• Ipconfig Displays The Default Gateway If It Is
  Assigned.

19
Example 2, Understanding Ipconfig /All

• If A Duplicate IP Address Exists
• Ipconfig Indicates IP Address Is Configured.
• Subnet Mask Is 0.0.0.0.

20
Example 3, Understanding Ipconfig /All

• No Server Running The DHCP Service On The Network
• IP Address Provided By Automatic Private IP
  Addressing
• IP Address Is 169.254.0.0 Through 169.254.255.255

21
Using Ping

• Use To Test Connectivity
• Use To Determine If A Host Is Available And
  Functional

Network Monitor Driver 2

• Collects And Displays Statistics About Activity
  Detected By The Network Card.
• View These Statistics On A Computer Running
  Network Monitor Agent Service.
• Use Microsoft Systems Management Server And
  Network Monitor To Collect Statistics From
  Computers Running Network Monitor Agent.

26
Introduction To Network Bindings
27
Combining Network Bindings

• You Can Select Which Protocols Are Bound To The
  Network Adapter Cards.
• When Adding Network Software, Windows 2000
  Automatically Binds All Dependent Network
  Components Accordingly.
• Network Driver Interface Specification (Ndis) 5
  Provides The Local Security Database That Windows
  2000 Uses To Validate The Logon Information.

28
Configuring Network Bindings

• In The Network And Dial-up Connections Window,
  Click Advanced, And Then Click Advanced Settings
  To Configure Network Bindings.
• Only An Experienced Network Administrator Who Is
  Familiar With The Requirements Of The Network
  Software Should Attempt To Change Binding
  Settings.

29
Specifying Binding Order

• You Can Specify Binding Order To Optimize Network
  Performance.
• To Specify The Binding Order, In The Network And
  Dial-up Connections Window, Click Advanced, And
  Then Click Advanced Settings.
