I have Problem In me server *NETWORK*

Hi, i have a Pentium 4, exactly the same as the CPU in the picture
http://i39.tinypic.com/sb7sed.jpg
and sometimes my network go down without reason, at least i don't know why. I know that sometimes it go down because my ping test fails replying
Ping request time out.
But is just sometimes and then a few seconds it come up again....
in that server is running a PBX service and the OS running there is Fedora Core 8. Everything is running well excluding the network device (the network device is integrated in the motherboard)

What you recommend me?
When i run lspci in the command line i get this output


Code:
[root@TornadoR3 ~]# lspci -m

[root@TornadoR3 ~]#



show packet counters on said network device


Code:
ifconfig <ethX>
check network interface is operating at correct speed and duplex

Code:
mii-tool -v

or if your device does not support MII, use ethtool


Code:
ethtool <ethX>

show some logs

What you think about this outputs and about my problem?

i dont think nss has anything to do with the problem.



i think you will have to use normal network troubleshooting techniques from a remote host or another host on the network
..

any of

ping
traceroute
netstat
mtr


might help you find the problem.
also tail the message log file. and check dmesg too.

Code:
tail -f /var/log/messages

Code:
dmesg

are the pings still failing??
mdns uses multicast to find hosts on a small network, so it could have been the problem,but the question is - is ping working ok now?
