The computer name 'martin-RB042AV-ABA-a1410y' was set by Linux Mint when it
was installed. I'm not sure I can change it. I check it on the Mint forum.
I'll turn off the smb... feature and see what happens. Yes the ports listed
below are open and set to pass through the firewall. Should I unset the
netbios name". Going to try the modification to the ufw rules file as
suggested by Reinl.

First who set the the computers hostname to 'martin-RB042AV-ABA-a1410y' ?

There are two 'netbios' names'
The 'netbios name' which is the computers short hostname The 'netbios domain
name' which is the computers dns domain name.

You can set 'netbios name' in smb.conf, but if it isn't set, Samba will set
it for you. Well it would normally, except that it has to be 15 characters
or less and yours is 25 characters. You need to shorten the hostname.

For security, you should turn it off, but then networking browsing will not
work, you will need to map drives etc.

Are these ports open on the Mint machine:

135 	tcp
137 	udp
138 	udp
139 	tcp
445 	tcp
