Fixed: Remote Desktop "An authentication error has occurred" CredSSP issue
This video shows how to fix an issue that can occur when using Remote Desktop in Windows 10. The specific error is:
"An authentication error has occurred. The function requested is not supported.
Remote computer: (IP or hostname)
This could be due to CredSSP encryption oracle remediation."
This issue is caused by a Windows update that patched a vulnerability in the authentication provider that Remote Desktop uses. It can be resolved in the group policy editor using the steps I outline in the video.
