How to solve this issue?


After installation of Sophos SafeGuard Disk Encryption, the Remote Desktop Connection does no longer work correctly. Either unlocking a locked desktop remotely is no longer possible, the desktop gets unlocked and locked again after one second or the terminal session fades to black/blue and working is no longer possible.

Please check the value of the registry key 'ShowLockDialog' and set it to '1' if needed.


Remote desktop should now be possible again.
