I have 5 computers running with IP address 192.168.x.x. Subnet mask: 255.255.255.0. While doing the network checking for the TCP/IP communication, I ping to respective com, and are succeccfully with all the reply to respective com. But on the next day, The 5 computers are lossing communication and unable to ping to each other and loop back and local IP address (itself). I suspect maybe it because I have installs firewall software that causes the IP address: 127.0.0.1 by mistaken or maybe have been configuration by auto setting from firewall software? Kindly advise. Thank you :rolleyes:
Thank for your reply. I have removed the program, and able to get the transmissions going now
Question: how to keep away virus from going around the network with low cost or no cost? By setting some of the ports access to disable, and yet able to use Internet and email. Pls advise. Thank you.
