I have Windows XP Pro SP2 w/Firewall in full "stealth" mode (no open ports); using 2 NICS w/ ICS, unbound file & print sharing by unchecking it in the components list for the internet adapter. So all is well security-wise and LAN PCs can share resources... BUT... every time I reboot, the file & print sharing exception is checked and ICMP is enabled. Even with the f&p sharing component unchecked on the internet NIC, I still don't want to respond to outside pings, and what is causing this behavior? I can uncheck the f&p sharing exception which automatically unchecks ICMP as well, and it stays that way as long as the PC remains up and running but upon reboot there it is again.
