smbstatus will also tell you who has an active connection to what
shares, even if they have yet to actually open some file.

while it's possible for someone to open a file in app that reads to
ram then closes, such as notepad.exe, making edits and letting them
sit without saving for long enough that an smb client would disconnect
the session is unlikely given the "save often" mentality that most
have gotten from using PC's.  From application crashes, to power
outages, to 2 year old kids pressing buttons, save often!
