I use Ethernet network connections at home to create fast home network transferring files between my macs. One of the biggest problem I found is often that one mac cannot see another. It shows "connection failed" in network and there is a "connect as" button that does nothing when I click on it. It's funny because while say my macbook pro cannot see my iMac, my iMac can freely access my macbook pro. The only way to resolve this is to restart my macbook pro - which is very inconvenient. Is there a way to quickly reset the network connection without rebooting my computer? Thanks.
