Why on earth are you suggesting to turn off ICF????
ICF may or may not be up2par but it's better than no firewall at all.
AFAIK s/he didn't tell us what firewall s/he is using so it may or may not be ICF.
Isn't Start->Run... services.msc<ENTER> a whole lot easier?If your running Windows XP pro...you can turn off the Internet Connection Firewall via services...goto start->run then type in mmc...once there hit ctrl-M then goto add...scroll down to services then click add and then finish...close the windows out
