I am on a small network running windows 98 & nt. I am using netbui for network & tcp/ip for internet. I am sharing a cable internet connection using Linux Lrp and 10\100 netgear switch. I have one machine that has lost tcp/ip connection although it dynamically recieves an ip address and all of the other needed settings on boot up. But I can not browse the internet or ping any machine within the network or internet sites. Also none of the network machines can ping this machine, But it will do a loopback ping. Is their any type of software that will trace what is blocking communications on this machine.
