First of all you need the following packages to be able to access windows file servers:
stephane@jerry:~$ sudo apt install smbclient smbnetfs
These packages give you some tools to check that you are able to access Windows share folders through the network using SAMBA protocols.
Here is some useful information : https://fr.wikibooks.org/wiki/Administration_r%C3%A9seau_sous_Linux/Samba
To test the server accessibility
stephane@jerry:~/Desktop$ smbclient -L corto -W phona -U stephane.guilet
The output gives you some useful information about the available services. In fact you can't access the root of CORTO but the services OK.
stephane@jerry:~$ smbclient -L corto -W phona -U stephane.guilet
WARNING: The "syslog" option is deprecated
Enter PHONA\stephane.guilet's password:
