RDP Error “CredSSP Encryption Oracle Remediation”


 Unable to RDP to Machine: CredSSP Encryption Oracle Remediation


 Windows Update:


The fix is to open your local group policy settings and do this.

Computer Configuration -> Administrative Templates -> System -> Credentials Delegation–Encryption Oracle Remediation

enable and set to ‘vulnerable’.

If Windows Home edition reg key change…

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystemCredSSPParameters] “AllowEncryptionOracle”=dword:00000002

I had to create the CredSSP key, then the Parameters key, then the dword value as none of them existed.
