This is essentially a confirmation of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=825380

I had the combination of smb and autofs working in Ubuntu 16.04 and then
recently upgraded to 18.04.  I hadn't checked my back-up logs that used
autofs+smb for a while but today noticed that autofs claimed that it
could not resolve my Win10 hostname (the remote backup endpoint).  I
found the above Debian bug report and can confirm that the issue is
present in 18.04.

Steps to reproduce:
# ping abcomputer
ping: abcomputer : System error

# nmblookup abcomputer
192.168.1.8 abcomputer<00>
192.168.5.1 abcomputer<00>

Note the 192.168.5.1 IP is a Virtualbox host-only interface on the Win10
machine.  I then remove the host-only interface from the Win10 computer

# nmblookup abcomputer
192.168.1.8 abcomputer<00>

# ping hyperion
PING abcomputer (192.168.1.8) 56(84) bytes of data.
64 bytes from 192.168.1.8 (192.168.1.8): icmp_seq=1 ttl=128 time=0.533 ms
