I see what you are referring to. It doesn't make any sense--the options are:
folder (what's that?)
username (windows or unix?)
name to use for connection (eh?)
This thing is just a front end for smbclient, the syntax of which is:
smbclient -U valid_win_user //server/share
So you can see what the arguments to smbclient are, and are not. In any case I tried it with every combination of input that I could think of, and AFAIK the process just died.
If you are using mandrivel, er, mandriva, you can use the MCC to browse and mount windows shares. Then the mounted windoze shares become a transparent part of your file system. I used to run mandriva and it always worked for me.
