It appears the Ethernet port on my iMac 10,1  (Nov '09) stopped working suddenly.  When I plug the same cable into a laptop, the laptop connects to the Internet without problem. Checking System Preferences\Network\Ethernet says "Not Connected".  Assist me\Diagnostics\Ethernet says Ethernet"failed" and Network Settings "failed".  Since I know the cable works with the laptop, I clicked continue, and I get the message"unable to connect to the Internet Network Diagnostics cannot fix the current networking problems".  Is there some software I should reload? Is there some other diagnostic that I can run to find out if the logic board has gone bad, (the Ethernet port is an integral part of the logic board, isn't it?).  The AirPort works fine.

iMac, Mac OS X (10.6.8)
