XP Firewall is gone from control panel

I was just on my friends XP machine. I wanted to start a log on his firewall, but to my suprise, there was no icon in control panel for it!

I couldnt find it anywhere.

Does anyone know what could be up with this??

I will be installing Zone alarm for now, but where in the world could this thing have gone??

He is on dial up (it is all he can get where he is located). Running XP home.
