Ok at home we have 2 machines connected to a Linksys Router. Through the router I can see in the DHCP client listing and 2 addresses being leased out. PC 192.168.1.100 Laptop 192.168.1.101 Ok so I try to ping from PC to laptop and laptop to PC. I get Timed Out errors. However, I can ping the router itself. 192.168.1.1 If I turn the windows firewall off I can ping each machine fine. I am wondering what service is used when pinging and if i can include it as an exception. I have been trying to send console messages between the PCs as well but it says I might have typed the name or address incorrectly or to try later. Both PCs are on the same domain too. Any ideas?
