Proper Duo Network Config

Thank you for the advice. I turned off WINS. Ironically I was only running it to try to help the NAS resolve computer names. This helped stabilize things a bit. Also, switching both the Duo and NV+ to take a DHCP-given IP address straightened out some more funky behavior (despite the Duo's warning about getting a bad IP, it is fine). So now my network is perfectly stable. And backups were working fine so long as I used IP addresses instead of names for a while, until I expanded the NV+ with another drive. Now backups don't work at all... Otherwise everything looks fine. Even Photos II works. But no backups...very disappointing. To be clear, I have absolutely no problem resolving the names of the NASes. It's the NASes that can't resolve the computer names.
