Q. How do I start using the firewall in Windows XP 8 Months, 1 Week ago
A. If you're running Windows XP SP2 the new Windows Firewall is already turned on. For more information, see Understanding Windows Firewall.
If you're not running Service Pack 2, the steps on the Protect Your PC page help you turn on the Internet Connection Firewall in Windows XP. Follow these steps if you have a single computer that you connect to the Internet.
