Dear Community,
Log in under SSH and execute:
cd /etc/samba
Firstly, make backup:
cp -pr /etc/samba/smb.conf /etc/samba/smb.conf.bak
Secondly, open smb.conf, scroll down to [Configuration] section and replace:
browseable = yes
with
browseable = no
You will notice the effect immediately with no reboot required.
