You need to use smbmount or gvfs-mount to mount the shared folder to a directory in Linux, and then create a symlink to that mount point from ~/.wine/dosdevices/D: See also http://www.winehq.org/docs/wineusr-guide/misc-things-to-configure http://bugs.winehq.org/show_bug.cgi?id=425 This really needs an FAQ entry.
