Subject:
HOW TO CONFIGURE SAMBA FOR USE WITH LANTASTIC.

Solution:
LANtastic only supports the original SMB 1.0 protocol, and later versions of SAMBA default to disabling SMB1 .
To allow SMB1, you will need to edit the smb.conf file, which is the configuration file for the Samba suite. Samba refers to SMB1 as "NT1", so the server (and/or client) min protocols should be changed to:
server min protocol = NT1
client min protocol = NT1

See:
Server Min Protocol and
Client Min Protocol

*WARNING:
As of Samba version 4.11, the ability to set NT1 (SMB1) as the minimum protocol has been disabled. One suggested workaround is to also add "min protocol=NT1" in the smb.conf global section.

At the time of this writing, another workaround is to set one of the lesser protocols as the minimum, such as:
CORE: Earliest version. No concept of user names.
COREPLUS: Slight improvements on CORE for efficiency.
LANMAN1: First modern version of the protocol. Long filename support.
LANMAN2: Updates to Lanman1 protocol.

However these workarounds my be disabled in future versions of Samba, in which case you may need to revert to Samba version 4.10 or earlier.

After making changes to the smb.conf, Samba should be restarted:

sudo service smbd restart
sudo service nmbd restart
