samba - Oct 2002 - smbpasswd command for windows or something else

On a Linux machine you can use smbpasswd -r to change your password on a 
remote smb server .  Is this command available for windows clients?  If 
not, is there any other way to allow users to change their samba 
passwords without being part of a domain?

Thanks,
