Hi AaronBre,
My apologies if the above steps did not work for you.
Let's try to edit some policies to see if it would help. Perform the steps below on the computer with the USB CD Rom Drive.
- Click on Windows > type edit group policy > Click Edit Group Policy
- In the Local Group Policy Editor, go to Computer Configuration -> Administrative Templates -> System -> Removable Storage Access ->
- Click on the folder for Removable Storage Access. A list of entries should appear on the right side.
- Kindly locate All Removable Storage: Allow direct access in remote sessions and double click on it,
- On the new window that appears, make sure it is set to Enabled.
- Click Apply, Click OK.
- Restart your computer and then try to RDP.
Let me know if this helps.
