In the Dial-Up Networking window, select the connection. Right-click the connection In the Properties dialog box, choose Server Types. Figure A-12 shows the default Deselect Log on to the Network, NetBEUI, and IPXSPX Compatible. 6. Click OK.

Appendixes Figure B-14: Look for the protocols area. For information about the other options in the Server Types tab, see Appendix C.

5. In the Allowed network protocols area, make sure that TCPIP is selected. Deselect any

protocol you won’t be using with this connection, such as NetBEUI and IPXSPX.

6. Click the TCPIP Settings button. The TCPIP Settings dialog box appears, as shown in

Figure B-15. Figure B-15: Configure TCPIP settings for dial-up networking. Tip Appendix B ✦ IP Addressing

7. Choose the options and enter the IP addresses for the connection, as explained in

Table B-1.

8. Click OK to close the TCPIP Settings dialog box. Click OK again to close the connec-

tion’s Properties dialog box. Table B-1: TCPIP Settings for Dial-Up Networking Setting Description Server assigned IP address Use this option if you attach to a DHCP server. Specify an IP address Use this option if you want to specify a static IP address. IP address Enter the IP address of the computer to which the connection attaches. Server assigned name server addresses Choose this option if the server to which you’re attaching assigns DNS server IP addresses. Specify name server addresses Choose this option if you want to enter the DNS or WINS server IP addresses manually. Use IP header compression Check this box if you want to compress the headers for your network packets sent to this computer. Using compression speeds up transmissions. Use default gateway on remote network Check this option if a gateway separates your computer from the computer to which you want to connect. Comprehending the dial-up adapter TCPIP settings You are probably wondering why you didn’t configure the TCPIP for dial-up in the Network dialog box in the Control Panel. The Network dialog box contains a dial-up adapter that is bound to TCPIP and the Microsoft Client for Networks. As mentioned, the adapter is a device driver that enables your modem to attach to other computers via the telephone lines. If you select the dial-up adapter in the Network dialog box and then click the Properties but- ton, you’ll see the warning dialog box shown in Figure B-16. Figure B-16: Windows warns you away from the dial-up adapter TCPIP settings. Appendixes The warning tells you that you should set TCPIP configurations individually for each connec- tion. If you set the TCPIP settings in the Network dialog box under Dial-Up Adapter, those settings apply to all connections you create. In order to create different connections — say, for the Internet, for a work network, or for a home network — you configure TCPIP for each connection in the Dial-Up Networking window. Working with TCPIP and Windows XP Windows 2000 and XP install with the TCPIP protocol. You can connect a new XP computer to a network, and the new computer figures out the protocol settings and joins the network without much configuration. You should, however, understand how to change configuration yourself, in case you need to change the network. For more information about setting up a network card, file and printer sharing, and other net- working software, see Chapter 10. To set up or edit TCPIP in Windows XP, follow these steps:

1. Right-click My Network Places and click Properties from the pop-up menu. The

Network Connections dialog box appears, as shown in Figure B-17. Your Network Connections dialog box might not display the same items in the figure.

2. Right-click the Local Area Connection and click Properties. The Local Area Connection

Properties dialog box appears, as shown in Figure B-18. You can rename the Local Area Connection using the same pop-up menu if you prefer to call it Home, or Plumleys, or some other name more true to your personal network.

3. Click the Internet Protocol TCPIP to select it, and click the Properties button. The

Internet Protocol TCPIP Properties dialog box appears, as shown in Figure B-19. Figure B-17: Network Connections shows LAN connections, Internet connections, and dial-up connections. Tip Cross- Reference
