I have just bought a new MacBook Pro after my previous one died ( mother card seem to had been the problem). In this one like in my previous the computer's local hostname keeps telling me that the "MacBookPro-BC-617.local" is already in use on this network and changes the name of my MacBookPro-BC to 658.local.
This takes place every day and almost every 10 - 20 minutes. I'm using Mountain Lion. What could be causing this and how could I get rid of it?
