man smbclient
       -W|--workgroup=domain
           Set the SMB domain of the username. This overrides the default domain which is the domain defined in smb.conf. If the
           domain specified is the same as the servers NetBIOS name, it causes the client to log on using the servers local SAM (as
           opposed to the Domain SAM).
       -m|--max-protocol protocol
           This allows the user to select the highest SMB protocol level that smbclient will use to connect to the server. By default
           this is set to NT1, which is the highest available SMB1 protocol. To connect using SMB2 or SMB3 protocol, use the strings
           SMB2 or SMB3 respectively. Note that to connect to a Windows 2012 server with encrypted transport selecting a max-protocol
           of SMB3 is required.
