I need help plz, fire wall block

my borhter is away, and i cant get the fire wall away. its a sygate fire wall, and i cant diable it. but i remember that he disabled it for me once, by going to start, then run. he typed in something, then all the current programs that are running poped up, and he clinks from auto to stop. and the problem is fixed. i need to know what he typed into the run box, some one please help me!!

I'm not sure it will be good to mess with the fire wall if you don't know exactly what you're doing... you might end up with bunch of viruses.
if you feel responsible though, go to Start --> Settings --> Control Panel --> Administrative Tools --> Services. the list of services will appear, choose the firewall service, right click and Stop it.
