Ping

By LMillerMT ·
I have a desktop and a laptop. These are connected via a Linksys router. I also use ZoneAlarm Security Suite. I can ping from my desktop to my laptop, but I cannot ping from my laptop to my desktop. I do have access to Network Neighborhood. I cannot run //ipaddress from my laptop to my desktop.

What is still being blocked?

ZoneAlarm

by scott_heath In reply to Ping

My guess is that the Zone Alarm is running on the desktop. I am not a Zone Alarm guru, I actually prefer to only use a hardware firewall on the network and not software firewalls. In any case if you can ping it's because a firewall (ZoneAlarm or Windows) is set to drop ICMP packets. This prevents basic Denial of Service attacks. I believe port 139 maybe be used for file and printer sharing, so if this blocked as well it will keep the \\ipaddress from working. Most firewall packages have levels of default security. Try changing Zone Alarm to Home Network or Safe Network. This will typically protect gainst malicious attacks but leave things like ICMP and File Sharing from the same network enabled.
