In spite of all setting of Samba on Debian buster not accessing Windows Network from Explorer or not working smb://192.168.1.3 (window ip address or computer name)
After the successful installation of smbclient opens the up the /etc/samba/smb.conf file and right after the
workgroup = WORKGROUP
add the below line to change the default.client max protocol = NT1
if not working try...
client min protocol = NT1
you just need to save the file and reboot the system.
Note: Reboot is necessary otherwise the above solution will not work.
