Samba client requires the presence of a configuration file - which may be empty - but it must be there.
Browsing a samba service for shares has been disabled for quite some time.
You will have to connect directly to the share and provide your credentials to access the share. Only then you will be able to see what other shares the service provide.
This is a consequence of various ransomware attacks which spread themselves using netbios vulnerabilities.
Some advanced samba functionality wil require you to install the samba package - example is wins lookup and nmb.
