What setting in Windows 8.1 is causing the automatic mapping of several shared folders named media? 

I work in a university environment with staff, faculty, and students using wired and wireless networks.  I have a user with a Surface Pro 3 that has started to automatically map, what seems like random addresses on the wireless network, to file shares named media.  When I setup these computers for the users I always have the media sharing turned off and I've never had cause to use it myself so I'm only a little familiar with what the settings do.  I've tried to change my own settings to reproduce the problem but I can't seem to find the correct setting so that I can reverse it.  Can someone point me in the right direction?

Thanks,
