My brother just got a new iMac and set it up. Everything was going well. He has a wireless router in that he is ethernet too from the iMac. What started happening is when he reboots, he get's a message on startup that the Host Name Mark's iMac already exists and this iMac has been renamed to ark's iMac (2) and if he reboots again it is then Mark's iMac (3) and so on. The he loses his internet connect on all the devices in the house. I told him to go into System Preferences / Sharing and rename it to something else and reboot.
He does that and the new name comes up with the same above issue. iMac or router problem?
Any thoughts?
Thanks in advance.
