as if u have NIS... the Norton firewall is included in the pakage...
so its not a better idea after buying NIS05 then turn off the Norton firewall & installing another firewall... so i say if u have bought NIS05 then stick with the NIS05 norton filewall...
but if u have option & want to try other firewall then better get NAV05 & then install aother firewall...
for firewall ZAP6 rules....
& to start windows Firewall
check this 2 link.. follow the instruction there....
Link 1 &
Link 2
by the way hope u have tried to enable the service By right clicking on any network connection then Properties then Advance & seting up the firewall...
