Hi,
it shows the following error: sh: ,sec=ntlm,soft,uid=45,gid=45,rsize=16384,wsize=17408,iocharset=utf8,cache=none,ro: command not found
Command not found means, that there is something wrong with your mount command.
Please post the settings you made on the "NAS mounts" option page.
With guest access i never had luck.
