This thread, http://forums.zonealarm.com/showthread.php?t=75210, is closed but I would like to add something.
This morning I restarted my computer and I got the Zone Alarm window informing me of a new network, 192.168.1.0/255.255.255.0, again. There are only two options, to make it an internet zone or a trusted zone. I opted to make it an internet zone.
When I opened the Control Center, all of the zones I had previously created were gone. The ONLY zone listed was the new one just added. I was able to access web pages but not other computers on my network.
I was concerned that the Local Host and DHCP server were not listed any longer and I decided to follow the reset instructions given by Guru in the thread referenced above.
As ZA was resetting, the "New Network" was found again so I set it to trusted this time. In the Control Center, I now have these:
New Network 192.168.1.0/255.255.255.0 Network Trusted
Mapped Drive 192.168.1.140 IP Address Trusted
DHCP Server 192.168.1.1 IP Address Trusted
There is no listing for Local Host as there was initially. Is there anything to be concerned about or to do here? Thanks.
