Could be a problem with the nic. Could also be that it is a dhcp issue;
do you have the second nic connected to a dhcp server (in your router
for instance)?

For simplicity, I have both nics in my server set as fixed IP's. If I
set the second nic to dhcp and it is not connected to anything then I
get the same message that you do.

Try setting it to a fixed IP, then:

sudo /etc/init.d/networking restart

and see what shows up. If that works, then it is most likely a dhcp
issue. You may have to go into you router and clear your dhcp table.
