samba - Sep 2016 - Ubumtu 1n.04 - no network machines visible

Since  upgrading  to  Ubuuntu  16.04  LTS from 14.04 LTS, I cannot see
either  my  Windows  PC  or  any  of  three  Linux-based NAS in either
"Network" or "Windows Network". Both windows have no icons.

After  the upgrade, I did apt-get update and apt-get install samba and
apt-get install winbind

My   Windows   7   Ultimate  PC can see the Linux PC and the three NAS
without problem. It can even read and write to the shared directory on
the Ubuntu 16.04 PC.

Ping  to  all  four  devices works. Everything has a static IP address
192.168.1.xxx. All the connections are wired.
All have the same workgroup name.

I even added all the IP addresses to /etc/hosts and /etc/lmhosts

Thanks in advance for any pointers as to where to look next

Here's an update

I added the following three lines to smb.conf

client lanman auth = yes
client ntlmv2auth = no
client maxprotocol = LANMAN2

Now  smbtree actually shows the shares (previously smbtree didn't show
anything)
The Windows  PC  and  the  three  Linux NAS now show in "Network" and
"Windows Network"

The  Windows  PC asks for a password*, but the Linux boxes show "Cannor
retrieve  share  list  from  server".  I am  not  too worried about the
Windows  PC  as it can access all the Linux devices, but why can I not
access Linux devices from a Linux PC?

*I  have  had  this  password  issue  in  the past with the Windows PC
accessing  the  oldest  of  those  Linux devices and it was fixed with
policy editor to stop ntlvm2auth

Very  strange.  The  Windows  PC  can  access everything. The Linux PC
cannot access anything.
