Networking: Protocols & TCP/IP

2

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

6

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

12

Configuring TCP/IP To Obtain An IP Address Automatically

04/13/23 15:51 Windows 2000 Professional / Chapter 7 12

13

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


If A Duplicate IP Address Exists– Ipconfig Indicates IP Address Is

Configured.– Subnet Mask Is 0.0.0.0.

20


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

22

Using Ipconfig And Ping

• NetBEUI– Small, Fast, And Efficient Protocol– Not Routable

• DLC - Old Protocol for IBM mainframes

• Appletalk• IPX/SPX

25

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.
