Zone Alarm displays an internet-zone network named after the computer's ethernet adapter. The IP range on this network (which is not editable) overlaps the range used by the router when it assigns IP addresses via DHCP. Occasionally, a PC on the network gets one of these overlap addresses (i.e. 192.168.1.42), and then it cannot use the network.
How does one reset/edit the IP range of the internet-zone network that corresponds to the ethernet adapter?
Other facts: 1) disabling ZA fixes the problem 2) when router-assigned addresses are not in the internet zone range, all works fine. 3) Ping always works for all pairs.
