Loss of IP

[rolfea]

Hi guys

For some reason, over night, a iMac G5 lost its connection to our Xserve and self assigned itself an IP address to a 169.etc address, therefore students couldn't sign into their work areas. The G5 is about 4 years old.

I've tried setting both a manual IP and a Manual IP with DHCP. Both shown to be unsuccessful in the directory utility showing it still hasn't connected to the Xserve after a reboot.

Am I right in thinking that the NIC has died inside the Mac? Is there a hardware diagnostic tool on a Mac that can check it?

Silly question- have you checked that it isn't the cable? Swap it out and see. Then use this and see if it helps any:

Means I don't have to type all that out!

i tried pretty much all of those and i did try swapping over the cable.

I also tried re-patching it to another port in the switch which worked for a while,died again, but is now working again
