The Network window in System Preferences continuously switches between cable connected and NOT connected.

All the newest updates are installed on our G5 XServer 10.3.2.

Same problem after the Apple dealer swapped the motherboard from another G5 and an external NIC.

Has anyone else seen this problem?

Could this be the reason for all the freezes reported on other treads?

You have of course checked the cables you're using? All of them, the connection to the wall sockets, the in wall cables, the patch leads, the ports on the switches...

Yes! We've checked and rechecked everything. I didn't notice this problem with OS 10.2.8. The Apple dealer had the same problem at his shop.
