I would boot the server from a LiveCD or two and test network 
connectivity.  If it works from any one of these LiveCDs than the network 
card works and it could be a configuration issue in your installed CentOS. 
If it doesn't work on any of these LiveCDs that are all using different 
drivers, then it might be the card.  Also .. since this should be easy to 
do, switch network cables (in place, keeping their existing switch ports) 
with another system that is running fine.  If the other system starts 
exhibiting strange issues and this system magically starts working fine, 
it could be a cable or switch configuration issue.  Although most people 
don't have these sitting around, you could connect a USB nic to the 
machine and see if the problem occurs with the installed CentOS but using 
a different NIC without cracking the case.

Hope this helps,
Barry
