Hi,
I understand there is not much to be done on Meraki.
You may use DHCP Option 44 & 46 on your DHCP Server if you running one.
Incase you are running DHCP on MX. You may be interested in checking this Url

If you are not running a DCHP Server. You may point the windows clients to WINS manually.

Note: I have never used WINS though. DNS Server does take care of resolution for my environment however I understand there are differences between both the services.
