No directory ownership on CIFS mount

I have some directories that seem to be missing ownership. The files within them are all attributed to an owner but some (not all) of the directories themselves have an 'empty' owner, at least when viewed within Dolphin file manager. I've already run this command, as root, from the top-level directory:

chown -R 4242:fbox_cifs media/

but this doesn't enforce user 4242 as the owner of all the directories, only the files within them. How can I correct this? I'll send more detail if necessary but maybe there's a simple solution without me having to post several more paragraphs. gumb
