Trouble Connecting to a Network

If you're having trouble connecting to a network, take advantage of the surprisingly thorough network diagnostic tool buried deep within Windows XP's Help and Support Center. Click Start, Help and Support, choose Networking and the Web, click Fixing networking or Web problems on the left, and then select Diagnose network configuration and run automated networking tests on the right. Choose Scan your system. If you want the whole shooting match, click Set scanning options and check all the boxes before selecting Scan your system.
