q: how to close cd tray in windows server 2012 r2 i have burned a dvd on our remote server, using external usb dvd burner (matshita uj8e1).
after successful burn the system ejected the tray. now i have a problem with getting the tray with the burned dvd back to the drive.
i searched google and most of the things i found work only in win7 or xp or even below. i have tried using tools like wizmo, nircmd, but without success.
is there any way at all to remotely close a drive tray in windows server 2012r2?

a: that appears a laptop style slimline dvd drive which is spring loaded and not motorized, so no. it requires manual closure.
full sized dvd drives are motorised and often using that same eject function on a dvd drive that is already open will close it again.
the typical approach  on servers is rather than creating actual dvds, to create dvd images,  which you then download.

a: the matshita uj8e1 is a laptop-type unit (i guess its enclosed in some usb enclosure). those units do not have a motorized tray, therefore they require the tray to be mechanically pushed in order to close.
