Chapter 11, TCP/IP Configuration |1| Chapter Overview A. Installing the TCP/IP Protocols B. Configuring TCP/IP Chapter 11, Lesson 1 Installing the TCP/IP Protocols |2| 1. Using the Network And Dial-Up Connections Window |3| A. Contains icons representing the computer’s various network connections 1. A Local Area Connection icon appears for each network interface adapter installed in the computer. a. Clicking this icon lets you install, remove, and configure TCP/IP networking components for that specific network interface adapter. B. You create additional connections for modem or virtual private network (VPN) connections by clicking the Make New Connection icon to launch the Network Connection Wizard. |4| 2. Using the Local Area Connection Properties Dialog Box A. Central interface for installing and configuring basic networking components |5| B. Lets you configure the following Windows networking component types: |6| 1. Clients a. Client for Microsoft Networks b. Client Service for NetWare (required for Windows 2000 Professional) c. Gateway Service for NetWare (required for Windows 2000 Server) |7| 2. Protocols a. Internet Protocol (TCP/IP) b. NWLink IPX/SPX/NetBIOS Compatible Transport Protocol c. NetBEUI Protocol d. AppleTalk Protocol 3. Services a. File And Printer Sharing For Microsoft Networks (1) Enables the system to share its files and printers with other computers running Microsoft Windows (2) Not required for network communications C. Windows 2000 can use more than one of each networking component type, but the absence of a network interface adapter, protocol module, or client module would leave a gap in the protocol stack that would prevent the computer from communicating with the network. |8| D. Default Windows 2000 networking configuration 2 Outline, Chapter 11 Network+ Certification, Second Edition 1. Plug and Play installs the following default Windows 2000 networking components automatically when the operating system detects a network interface adapter. a. Client for Microsoft Networks b. Internet Protocol (TCP/IP) c. File And Printer Sharing For Microsoft Networks 2. You can remove these modules or add others as needed after the initial installation. |9| E. To install a Windows 2000 networking component manually: 1. Open the Network And Dial-Up Connections window. 2. Click the Local Area Connection icon, and then select Properties. 3. In the Local Area Connection Properties dialog box, click Install. 4. In the Select Network Component Type dialog box, select a network component type, and then click Add. 5. In the Select Network Protocol dialog box, select a component to install, and then click OK. |10| F. To remove a Windows 2000 networking component: 1. Open the Network And Dial-up Connections window. 2. Right-click the Local Area Connection icon, and then select Properties. 3. In the Local Area Connection Properties dialog box, select an installed component from the component list. 4. Click Uninstall. Chapter 11, Lesson 2 Configuring TCP/IP 1. Configuring Basic TCP/IP Properties |11| A. To open the TCP/IP client configuration interface: 1. In the Start menu’s Settings group, select Network And Dial-Up Connections to display the Network And Dial-Up Connections window. 2. Right-click the Local Area Connection icon in the Network And Dial-Up Connections window, and then select Properties to display the Local Area Connection Properties dialog box. 3. Select the Internet Protocol (TCP/IP) module in the components list and click Properties to display the Internet Protocol (TCP/IP) Properties dialog box. B. Automatic configuration 1. You use the Obtain An IP Address Automatically and Obtain DNS Server Address Automatically options in the Internet Protocol (TCP/IP) Properties dialog box to enable the DHCP client. a. Use of these options requires a DHCP server on the network. b. When these options are disabled, you must manually configure the TCP/IP configuration parameters. |12| C. The basic TCP/IP client configuration parameters are IP address, subnet mask, default gateway, and DNS server address. |13| 1. IP address Outline, Chapter 11 3 Network+ Certification, Second Edition a. Identifies the computer to the network b. Required for TCP/IP communication c. Must be unique on the network d. Must not be chosen at random e. Must be assigned by a network administrator |14| 2. Subnet mask a. Indicates which of the IP address bits identifies the network and which identifies the host b. Is required for TCP/IP communication 3. Default gateway a. Identifies the router that the computer should use to access other networks b. Not to be confused with an application layer gateway 4. DNS server address a. Identifies the DNS servers that the client will use to resolve host and domain names into IP addresses b. You can obtain DNS services from an Internet service provider (ISP) or run your own DNS server on your network. 2. Configuring Advanced TCP/IP Properties |15| A. To open the advanced TCP/IP configuration interface: 1. Open the Network And Dial-Up Connections window. 2. Open the Local Area Connection Properties dialog box. 3. Open the Internet Protocol (TCP/IP) Properties dialog box. 4. Click Advanced to display the Advanced TCP/IP Settings dialog box. B. The Advanced TCP/IP Settings dialog box includes the following tabs: 1. IP Settings 2. DNS 3. WINS 4. Options |16| C. Configuring advanced TCP/IP configuration parameters 1. Multiple IP addresses a. Used when a physical network hosts multiple subnets b. All IP addresses assigned to a network interface are active at all times. c. Configured in the IP Settings tab in the Advanced TCP/IP Settings dialog box 2. Multiple default gateways a. Alternate gateways are used only when the primary gateway is unavailable. b. Configured in the IP Settings tab in the Advanced TCP/IP Settings dialog box 3. DNS options a. Multiple DNS server addresses 4 Outline, Chapter 11 Network+ Certification, Second Edition b. DNS suffix settings c. Configured in the DNS tab in the Advanced TCP/IP Settings dialog box 4. WINS server addresses a. Required only on networks with computers running versions of Windows prior to Windows 2000 b. Alternative to the LMHOSTS file (1) LMHOSTS is a lookup table containing NetBIOS names and their equivalent IP addresses, which Windows can use to perform NetBIOS name resolutions. c. Configured in the WINS tab in the Advanced TCP/IP Settings dialog box 5. TCP/IP options a. IPsec b. TCP/IP filtering c. Configured in the Options tab in the Advanced TCP/IP Settings dialog box |17| Chapter Summary A. Use the Network And Dial-Up Connections window to manually install and configure the basic Windows 2000 networking components. B. Use the Local Area Connection Properties dialog box of a network interface adapter to install, remove, and configure the TCP/IP networking components for that specific network interface adapter. C. Use the Internet Protocol (TCP/IP) Properties dialog box to configure basic and advanced TCP/IP properties. 1. The basic TCP/IP properties are IP address, subnet mask, default gateway, and DNS server address. 2. The advanced TCP/IP properties are multiple IP addresses, multiple default gateways, DNS options, WINS server addresses, and TCP/IP options.
