How do I set up TCP/IP?:


While it won’t harm your computer when you check Internet Protocol (TCP/IP) settings with these directions, you should not change any of the information already in place.

If you do need to change any of the settings, be sure to have both the Windows XP installation CD and the network interface device drivers handy. You may need them to complete any changes to your system.

To configure TCP/IP for Windows XP:

  1. Select Control Panel from the Start menu.
  2. Select Network and Internet Connections, then Network Connections.
  3. Double-click the Local Area Connection icon under LAN or High-Speed Connection.
  4. Click Properties in the Local Area Connection Status window.
  5. Verify that your Ethernet card is displayed in the Connect using: field.

  7. On the General tab, verify that the Obtain an IP address automatically and Obtain DNS server address automatically buttons are selected. If they are not, click the circles next to the headings.
  8. When you are finished, click OK to exit the window. Click OK, then Close to exit the Local Area Connection Properties and Local Area Connection Status screens.
