Access denied error trying to enable BitLocker on external drive

Problem: you get an Access Denied error when trying to enable BitLocker on an external HDD or pendrive/flashdrive over a Remote Desktop (RDP) connection.

Fix: Launch the Group Policy Editor (gpedit.msc). Go to Computer Configuration > Administrative Templates > System > Removable Storage Access > All Removable Storage and set Allow direct access in remote sessions to Enabled.
