TNS-12542 / TNS-12560 / TNS-00512
I once received the TNS-12542 error when I wanted to start the listener on a Windows machine that was not connected to the internet:
TNS-12542: TNS:address already in use
TNS-12560: TNS:protocol adapter error
TNS-00512: Address already in use
64-bit Windows Error: 48: Unknown error
