[Samba] What is needed to allow Network Browsing of the file server in Windows

[Nick Howitt]

I am using Samba as a simple file server but I cannot browse its shares 
in Windows Explorer. I do not use SMB1. Am I missing a trick or is it 
not possible without SMB1?

I am using ClearOS7 with the Centos7 4.10.4 samba package. My cut down 
configs (with most of the shares removed) are:

[root at server ~]# testparm -s
Load smb config files from /etc/samba/smb.conf
NOTE: Service homes is flagged unavailable.
NOTE: Service profiles is flagged unavailable.
Loaded services file OK.
'winbind separator = +' might cause problems with group membership.

Server role: ROLE_DOMAIN_PDC

My PC's are set up by DHCP to use the server as the WINS server.

Although the role is set as ROLE_DOMAIN_PDC, my PC's are not domain joined.

Thanks,
