The error message says that the port is already in use and so it almost certainly is.
Either your node-agent is being started multiple times and the second one is failing, or some other process/service is snaffling the port temporarily.
1074 is above 1023 so [b]could[/b] be handed out to someone else, such as an incoming connection, but AFAIK most O/S's don't allocate connection ports below some fairly high value [I have NO idea what Windows XP does here], so this is unlikely.
I have no idea how to track this down on Windows, sorry.
