There are several small firewall programs (free or cost around $30)
such as Zone-Alarm, Outpost, etc., in addition to Windows XP SP2 firewall.
However, many windows based app will open ports when "necessary" therefore
to keep a spam sweeper on the same box is necessary.
You might also want to use foundstone tools to close the ports from time
That being said, I have tested Zone Alarm Pro and Outpost Pro in the
Windows XP. Both did worked and you may lock the box to its minimum if you
