I hate to revive this issue, but it still is a problem 5 days out of 7. It even happens during work hours now and it becomes a real issue if I'm not there (not too many people know how and what process to kill in task manager so that Sync can be restarted). I can say in pursuit of finding a solution I have moved off this machine as many scheduled tasks as I can and we really only have Google Drive, Dropbox and Teamviewer running on this server.
Are there any ideas as to why NSC Sync can be crashing? Sometimes error messages, most of the time it looks like it is running, but the task has stalled and clicking on the icon does nothing.
