Ch 7

  1. 1. Networking: Protocols & TCP/IP 1
  2. 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 2
  3. 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 3
  4. 4. Many Protocols – Many Uses Networking • 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) 4
  5. 5. Many Protocols – Many Uses Mail • 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 5
  6. 6. Many Protocols – Many Uses Some 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 6
  7. 7. Four Layers NOT! 7
  8. 8. Application Application Try 7 Layers Presentation Presentation • Police Session Session • Don’t • Need Transport Transport • To • Smack Network Network • People • Around Data-Link Data-Link Physical Physical
  9. 9. Application Virtual Application Presentation Virtual Presentation Session Virtual Session Transport Virtual Transport Network Virtual Network Data-Link Virtual Data-Link Physical Physical Physical
  10. 10. 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. 10
  11. 11. Options Used In Configuring A Static TCP/IP Address 11
  12. 12. Configuring TCP/IP To Obtain An IP Address Automatically 4/13/2010 6:03 AM 12 Windows 2000 Professional / Chapter 7 12
  13. 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 13
  14. 14. Steps In Automatic Private IP Addressing 14
  15. 15. Using TCP/IP Utilities 15
  16. 16. Testing a TCP/IP Configuration 16
  17. 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. 17
  18. 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. 18
  19. 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. 19
  20. 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 20
  21. 21. Using Ping • Use To Test Connectivity • Use To Determine If A Host Is Available And Functional 21
  22. 22. Using Ipconfig And Ping 22
  23. 23. Seldom Used Dinosaurs • NetBEUI – Small, Fast, And Efficient Protocol – Not Routable • DLC - Old Protocol for IBM mainframes • Appletalk • IPX/SPX 23
  24. 24. Seldom Used Dinosaurs • NetBEUI – Small, Fast, And Efficient Protocol – Not Routable • DLC - Old Protocol for IBM mainframes • Appletalk 24
  25. 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. 25
  26. 26. Introduction To Network Bindings 26
  27. 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. 27
  28. 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. 28
  29. 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. 29
