As far as I know, the XP firewall cannot block specific ports though it can
block some port functions. To block specific ports you need a more robust
firewall. Zone Alarm,
www.zonelabs.com and Sygate Personal Firewall,
www.sygate.com, both have free versions that will allow you to block the
ports you specify and much more.
