Ok. Networking. I can do that. For the purpose of testing, turn off the
firewalls on both servers.
1. Are you getting NIC lights on both servers and on the switch ports?
2. Have you verified the cables are not cross-over cables? Easiest way to
check, look at the two middle pair of wires on both ends. If they are the
same, it's correct. If they are switched, it's a cross-over, and the wrong
type of cable.
3. On one server type ping <address of other server>. Let it run.
1. Are you getting a response? If not, look at the NIC on the sending
server.
1. Is the NIC light flashing with each ping? If not, look at your
switch.
1. Are the switch port lights on both ports flashing in
conjunction with the ping? If not, your switch may be bad.
2. On the receiving server, is the NIC flashing with each ping?
Follow these steps from top to bottom. Post any probems or errors you are
having.
