There is no much overhead ( here a quick descritpion of the differences:
http://ubiqx.org/cifs/SMB.html#SMB.1.2 ). But the client may behave
differently based on what ports it binds to (445 available means the
server is win2k like, while 139 only is a strong indication that the
remote server is of NT class).
