I have both a Windows 10 machine and a NAS on my network and even with Samba installed I haven’t been able to see shares on the network without entering the address manually (eg;
smb://192.168.1.254). Turns out there is an easy fix in the Ubuntu forums that works for Kubuntu as well. You simply install Samba Client, backup the Samba configuration and then edit the Samba configuration file and restart Samba.
In a terminal;
sudo apt install smbclient
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf_backup
sudo nano /etc/samba/smb.conf
Instructions for Nano are available here. Arrow down until you get to workgroup = WORKGROUP, add a line by pushing enter and then write,
client max protocol = NT1
Close nano by pressing control and x at the same time and answering the questions. Restart the samba service with,
sudo service smbd restart
sudo service nmbd restart
And try to see your shares again. If you have any issues try running
testparm in the terminal. It tests the smb.conf file for mistakes and if you can’t figure it out well you can always copy the backed up smb.conf and start again.
