Re: firewall taskkiller
search for two programs,
one is called TLIST.exe
the other KILL.exe
They are both by microsoft,
Tlist is like a task manager but opperated from the command line.
Kill stops any process (even windows proteted processes), but you need the PID of the process that can be found using tlist.
you'll only be able to stop the process on machines you have the programs installed on, and only if you can run the programs on thet computer...
I don't think you'll find a way to stop a firewall remotly, most firewalls are designed to be pretty secure.
