The address at http://www.microsoft.com/catalog/display.asp?subid=22&site=10538&x=44&y=21 does not exist however the Microsoft site has various information about firewalls including the following:
Microsoft regularly releases improvements to Windows to help keep you protected from constantly changing Internet threats. Windows Firewall is one such improvement, first released as part of Microsoft Windows XP Service Pack 2.
Windows Firewall protects your computer by blocking communications that might actually be dangerous software trying to find a way to connect to your computer, rather than communications from a person or program you want to interact with. Windows Firewall is smart enough to allow connections from computers in your home and to block those connections from computers on the Internet. For example, Windows Firewall will allow you to share files or a printer between two computers in your home, but it will block any attempts from people on the Internet to connect to your computer.
