ethernet not found
there are 3 network interface cards in my linux box, All nics were working, but suddenly one of them stop responding.

Well, your output for some N/W commands show that you have three Ethernet controllers. What do you mean by "one of them stopped working" - I mean, which is not working?
What does ifconfig -a say? In my case, it is: Code:
eth0 Link encap:Ethernet HWaddr 00:13:D3:08:49:5E |
yes i have 3 physical NIC, and i have installed VMware server 1.0, my host OS is FC7, and guest OS is FBSD 6.2. i have also rebooted the system. but still i am getting same error

It may be a problem with your NIC (for eth1). Re-configure eth1 and then activate it. Restart the comp and try. It should work, if it does not, then it is a problem with the card. Also try it on any other computer, just to make sure that the card is alright.
