For security reasons the default setting in Windows is to prevent the the direct access to removable media over Remote Desktop sessions.
In my case I almost never use my main Media Center pc directly and instead I connect in using RDP, as a result this default causes me grief.
To change the setting all one needs to do is:
- Open GPEDIT.MSC
- Navigate to: “Local Computer Policy\Computer Configuration\Administrative Templates\System\Removable Storage Access”
- Find the “All Removable Storage: Allow direct access in remote sessions” option and enable it.
Now you can right click and eject the DVDs in Remote Desktop sessions.
