For some reason, my Mac Mini keeps giving me the "name of your computer "Mac mini" is already in use on this network. The name has been changed to "Mac mini (2)" message lately. It keeps going from there. For example, right now it's up to "Mac mini (5)". Does anyone have any idea as to what would cause this? BTW, this just started a few days ago and as far as I know, nothing has changed since then. Thanks.
