Answer 1

Just in case someone looking for a solution to this for a Windows based system or NAS:

There is a built-in function in Windows that shows you what files on the local computer are open/locked by remote computer (which has the file open through a file share):

• Select "Manage Computer" (Open "Computer Management")
• click "Shared Folders"
• choose "Open Files"

There you can even close the file forcefully.

Answer 2

The sessions are handled by the NAS device. What you are asking is dependant on the NAS device and nothing to do with windows. You would have to have a look into your NAS firmware to see to what it support. The only other way is sniff the packets and work it out yourself.
