Run the command "dmesg" to see the messages that were generated during the 
last startup. Also check the logfile /var/log/messages, as most diagnostic 
info goes into that.

Could be. I had a similiar problem with an old workstation that I turned into 
an in-house server. It has two network cards (only one is used). During each 
startup it randomly picked one network card to be eth0. If that's the card 
that's not plugged into the switch, then things go a bit haywire, of course.

If you have that same issue (only if!), then this can be fixed by hard coding 
the MAC address of the desired eth0 into the network configuration script.

In my cased I added the line ...

HWADDR=00:0C:6E:1A:71:45

... to /etc/sysconfig/network-scripts/ifcfg-eth0. Of course your MAC address 
isn't 00:0C:6E:1A:71:45, so you'd have to look up your MAC address with 
/sbin/ifconfig first and use that one instead.
