I have an intel imac running 10.4.7 and an ibook running 10.4.8. The imac can see the ibook in the network pane of Finder, but after starting up or waking from sleep, the ibook cannot see the imac in the network pane of its Finder. I have to reset personal file sharing on the imac in order to see it again on the ibook. I can't tell if the problem is with my ibook or imac. I think it's the imac. Any solutions to this?
