Ok I wont reply to that thread & bump it up.Instead lets continue with discussing your problem here itself.

After all that has gone into the thread did you ever considering checking the cable & the lan cards with your vendor or somewhere else for that matter?If not then I firmly suggest you do so first.Since you say that you can view one host but cant access it,it appears that the hardware may be right in place.

Lets troubleshoot step by step shall we?
1.ping your localhost
ping 127.0.0.1
What does it say?Do this for both hosts.

2.ping the IP of the localhost.
Say you assigned 192.168.0.1 as the IP for host A & 192.168.0.2 for host B,then
1.ping 192.168.0.1 from A &
2.ping 192.168.0.2 from B
What does it tell ya?

Post the results here.
