I have 3 pc’s on my home network. A laptop running vista home premium and 2 desktops each running windows xp professional.
I have the comodo firewall program on all 3 computers and each one is set up identically so that they can all talk to each other. However for whatever reason as of today I cannot get any of the machines to be able to ping the others - I did go to a command prompt and typed ipconfig to make sure that the addresses had not changed on any of them and that is not the case but whenever I try to ping one of them from another pc on the home network I keep getting request timed out.
Any suggestions on how to fix this would be so very much appreciated.
