My iMac's local hostname changed automatically?

[RedCroissant]

Hi everyone. I was about to shut down my iMac when I saw this message pop up on my screen.

"This computer's local hostname '---- iMac.local' is already in use on this network. The name has been changed to.."........-iMac-2.local'"

Why would this happen? I did recently upgrade my HDD to a 3TB one and cloned my original drive. Would this be the reason? Thanks for your help.

This usually happens when a ghost of your machine is on the network. A way to fix it is to uncheck the "Wake for network access" box in the Energy Saver pref pane. This is not something to worry about.

Hey Intell. Well what you said definitely worked. Thanks!

I should have come to this thread three error messages ago. Thanks for an easy fix, Intell.
