Tip 1: Check the Basics

WinXP configures TCP/IP as its default network protocol and it's all you need for both Internet and file sharing. If your Internet connection is working, then TCP/IP is installed and working, so you can at least cross that off your troubleshooting list. However - as anyone reading this article already knows - a working TCP/IP connection does not guarantee that file sharing is alive and well.

WinXP should also install and enable Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks service - both of which are required to share files and printers - on all network adapters. But you should first visit the Local Area Connection Properties (Start > Settings > Network Connections) for your network adapter (Figure 1) and make sure both are there and have their boxes checked.

Since you've got this window open, scroll down to the Internet Protocol (TCP/IP) protocol, click the Properties button, and the Advanced button on the window that opens. Figure 2 shows where you want to check next and what it should look like. The Enable NetBIOS over TCP/IP setting is needed because NetBIOS is what Windows uses for file and printer sharing.
