How to prevent Windows 8 computer from periodically checking a Samba share

Question

My Windows 8 box keeps nagging my QNAP TS-112 NAS, preventing it from spinning down its disk. Is there any way to prevent this behavior?

The connection log on the NAS looks like this:

Answer 1

Not a solution, just a workaround: disabled NetBIOS to get rid of this.
