I have had smart security for a while, i had to reinstall it on 2 of my pcs, before it was working fine, the issue i have is on my LAN, i cant browse to any shared drives anymore and other pcs do not see each other, i can ping them either no response but when i shut off the firewall it works fine, the entries in the firewall are all defaul to my trusted zone. i have both windows xp and media center edition pcs.
