RDP connection failure

[Don Hughes]

After updating the guest additions to 5.1.28 on a Windows 10 guest, I am getting errors with RDP clients - "Remote Desktop Connection has stopped working". Worked with 5.1.26, works on non-VirtualBox systems, and works if I remove the guest additions.

I get the following error logged:

See:

17082: defect: No more elevated rights after install of Guest Additions 5.1.28 on Windows, and

17084: defect: RCDMan, others failing in VBoxOGLpackspu.dll

The workarounds are to disable 3D Acceleration in the VM or revert to the 5.1.26 Guest Additions. (I was unable to do the second one because the bug stops you from running things with elevated privilege.)

Good luck!

This has not been an issue with VB 5.2.0 and the 5.2.1 Guest Additions.

You can close this ticket as fixed.
