Guest system is Windows 2000, clients are Windows XP and/or and Mac OS X 'Remote Desktop' apps.
If I run the guest from the command line as `VBoxHeadless -startvm Windows_2000`, either in a 'screen' session or in a terminal emulator in a VNC remote desktop login, then sometimes if I disconnect the RDP client and re-connect the guest screen will re-appear black.
The least invasive way to recover from this seems to be to `VBoxManage controlvm Windows_2000 savestate` in a separate terminal and then re run VBoxHeadless.
It's appears like the VRDP service that VBoxHeadless provides sometimes gets it's knickers-in-a-twist when the RDP client disconnects and needs to be reset.
This never happens if I run the guest in the VBox GUI client and connect to that with RDP clients.
Does anyone else see this behaviour and/or have a less invasive way of resetting the VRDP service in VBoxHeadless?
