Samba has 2 sides..
the server, for people to connect to you, config file smb.conf...
and a client, to connect to other shares..., smbclient.. (not controlled by smb.conf)
Browsing a net neighbourhood is a quite different programme, but uses these base tools..
Try mount -t smbfs -o username=user,password=password,uid=localuser,gid=localgroup //server/share /mnt/share
Make sure /mnt/share exists and is chmod 777 & localuser & localgroup are suitable otherwise you cannot read or write to the files.
username must have adequate permissions on the remote server as well..
Look at man smbmount for more options..
