You also need to decide whether you have a Hardware or Software problem. For that, the TCP/IP protocol supplied with Windows 95/98/ME/NT4/2000 offers a small,
but powerful tool called : 'ping'. TCP/IP PING can also be used to test WAN connections.
Now the question arises: What is ping actually doing? Remember the old war movies with submarines, where they are searching for each other sending out a search-signal, which sounds like 'ping' and where they get back an echo from another submarine? That is EXACTLY, what the 'ping' utility does in searching for other computers on the network!
