Yes, that's the one with the host entry

Unfortunately not, because the TW 20160613 release marked for me the switch
between working and non working, but the problem was much older. There was a
long period of time (let's say one year) in which the samba connections started
to become increasingly difficult. They were immediate at the beginning (as they
are now with the hosts setting) and then started to have lags of tenths of
seconds. After that, release after release, the lag approached the timeout
limit so I started to have timeouts but after few retries I still got to have a
connection. Finally with TW 20160613 it stopped working completely and I
decided to investigate with wireshark and found the hosts workaround.
I can try to go back to Leap 42.1 and openSUSE 13.2 and provide you a report
about those. And maybe also switching back TW from wicked to NetworkManager.

Yes, I do.

I think you got the point. Investigating a little bit, I found this [1], page
195, chapter "Understanding DHCP in a NAT Configuration" and chapter
"Understanding the NAT Device". Specifically: "The NAT device is a DNS proxy
and forwards DNS requests from the virtual machines to a DNS server that the
host system knows. Responses return to the NAT device, which then forwards them
to the virtual machines."
Of course I never had a DNS server on my Windows host, so it always relied on
netbios for local name resolution...
