"Server" is just terminology used. It has nothing to do with you running a "server".
You could check Error Console & see if related errors, Event ID 2011, turn up.
(Could be, with Win8 that things are different, even with the ID number? Don't use 8, so I wouldn't have a clue?)

What version of Everything are you running?
If not 1.3.3.658b, that's what I would suggest as a start.

That's what I show for my drives.
There may be a FAQ around or posts in the forums as to just what those numbers mean & how changing them may or may not affect things?
In any case, my 32768 KB is far smaller then your 940544 Kb, perhaps, depending on 'B' or 'b' (Bytes or bits).
Oh, heh,
