Not seeing all my networked drive recordings

I’ve got a newly rebuilt machine with Kodi-17, with the new default interface.
I have WMC running with ServerWMC on win7 on another machine. But now every once in a while, this annoyance occurs:
Sometimes when I turn on Kodi, it does not see all the networked recordings. hmm, perhaps I should open WMC itself and see if there is a temporary thing preventing WMC from seeing all the Networked recordings I didn’t think of that when writing this post. I did check that the Win-7 machine could see that network drive. But I left the machines on all night, and in the morning Kodi showed all the recordings again. Odd… Has this type of thing been reported before. Or perhaps this is a ‘serverwmc’ thing?

Does Kodi, or ServerWMC need more time to process the network-locations? Like a timeout-setting. There is a huge collection in that drive.
