Windows loses DNS and doesn't update

Windows loses DNS and doesn't update

I am running my own DNS on my local router for some hostnames in my LAN.
The DNS is working but from time to time windows loses the resolving. If I
access my NAS for instance it happens, that I can load it's web GUI at its
LAN FQDN but after a few reloads, Chrome tells me that the hostname is not
found. When I type nslookup into cmd, I get a response from my router but
pinging that hostname gives an error still that the name was not resolved.
A few attempts later, I can ping again and also access the GUI of the NAS.
Why does this happen and how can I tell Windows to either keep the
resolving or ask the router again when a name is not found in cache?
