Windows server 2019 remote desktop black screen

Question

Hello!
I have a windows server machine, sometimes when I try to log in to the computer with remote desktop I only get a black screen, the CRTL+ALT+END does nothing, and after some time the connection closes. If I open the computer via idrac othing works I cannot move the mouse, the only solution is the hard reboot. In the event viewer I have the following error: "The RDP display control module failed to change the session monitor layout. The operation failed with error code 0xFFFFFFFF."

We were having the same issue and found that the solution was to update the local Security policy on the server:

gpupdate /force and log out.

Log in with the problem account.

This should then log in and display the desktop successfully.

Hope that helps.

You may need this out of band update.

Hello DominikErdei

Thank you for your question and reaching out.

I can understand you are facing with RDP of your Dell server.

Kindly have a look below settings while you taking RDP of Server.

1. Please Un Check from RDP Window -> Experience -> Persistence bitmap caching
2. Please Un Check RDP Window -> Display -> change try changing color depth to 24bit (or less)
3. As you have Dell server try to upgrade its BIOS Firmware and Display Drivers
4. Run sfc /scannow from elevated prompt.
5. Run below DISM command from elevated prompt.

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

6. Disable any Antivirus program or Windows firewall you may have for temporary purpose.
