I have an Intel 24" iMac running 10.4.something (sorry I'm vague but I'm not at my office) The mac is part of a mini network of 3 iMacs, all working perfectly until yesterday when one of them wouldn't print to my network printer. I had a look at the network settings and it was showing "Built-In Ethernet" as inactive. All the other macs work fine. I tried switching the cables from other macs to establish if I had a cable problem. Still no success. I switched ports on the hub also. Same issues. As all the others are still working fine, I guess the problem must be with the mac, nothing else. The crazy thing is, the mac nadn't even had a reboot when it stopped working. I just woke it from sleep in the morning and that was that. Guess its not an early riser. Joking apart, can anyone help!!!!! Thanks. Dave.
