                         2
     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
   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
    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
   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

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
Options Used In Configuring A
    Static TCP/IP Address

Configuring TCP/IP To Obtain An IP
      Address Automatically

                    Windows 2000 Professional / Chapter 7   12
   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
Steps In Automatic Private IP
         Addressing




                 14
Using TCP/IP Utilities




              15
Testing a TCP/IP Configuration




                 16
           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
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
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
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
              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.
                        25
Introduction To Network Bindings




                  26
  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
 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
    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.
