Microsoft will base future patches on XP SP2. If you don't sort out your SP2 issues, then you soon will have an unprotected machine.
For those that think they can patch it with firewalls etc., take a look at the JPEG EXPLOIT.
Your post just shows that Microsoft didn't give you enough training to use the new firewall. And P2P users will complain.
I got the Sp2 update and after using it a day or two I immediately uninstalled it. The firewall interfered with most of my net usage even when turned off. My friend installed it also and it took over her entire PC. I would not recommend SP2 to anyone. DON'T USE IT !
