How To Fix CredSSP Encryption Oracle Remediation Error?



 While establishing remote desktop connections, your local computer can often not develop a secure connection with the remote computer. This happens due to issues with the CredSSP An authentication error has occurred. You would be looking for how to fix CredSSP Encryption Oracle Remediation error.

When the RDP establishes a connection with the server computer, Microsoft aims to ensure no hacker accesses the server. Therefore, the Oracle Remediation checks for CredSSP on both of them. If the local computer has it and the server does not, you encounter the error. So, let’s learn more about it!

What is CredSSP?

CredSSP, or Credential Security Support Provider, is a protocol that Microsoft Windows uses. It ensures secure authentication when a remote desktop client connects to a remote server.

The CredSSP takes the user’s login credential, encrypts it, and securely transmits it to the remote server. The latter validates these credentials. Once the remote server verifies the credentials, it accesses the remote client. CredSSP protocol ensures that only authorized individuals gain access to the remote resources. Thus, it protects from cyber attacks.

What is The CredSSP Encryption Oracle Remediation Error?

The error arises when there’s an issue in establishing a secure connection between the Remote Desktop Connection client and the remote desktop server. This issue usually comes up if the client machine is using an outdated version of Windows. This version doesn’t have full compatibility with the latest CredSSP protocol.

Similarly, it can also occur when the remote desktop server operates on an older version of Windows that does not support the latest CredSSP protocol. While connecting to an unpatched system, Windows 11/10 users do face the issue.

When the host computer aims to connect with the server, the Encryption Oracle Remediation tries to identify the client to prevent attacks. In such a scenario, Microsoft aims to be more strict with its policies. 

Thus, if the local computer has CredSSP installed, but the server doesn’t, you get the error. This is because Microsoft then doesn’t allow such a connection. 

Method 1: Use Local Group Policy Editor

If you don’t have a Windows 10 Home Version, then you can use the Local Group Policy Editor to change the Encryption Oracle Remediation setting of Microsoft. Though it will make the connection less secure, it is the solution to fix the error temporarily. Later, you can change the setting!

  • Press the Win+R keys and type gpedit.msc in the text box
  • Click OK to navigate to the location
  • In it, go to Computer Configuration and open Administrative Templates 
  • Click System and select Credentials Delegation from the left pane
  • Double-click the Encryption Oracle Remediation Policy and set it to Enabled 
  • Now, from the Protection Level, select Vulnerable from the drop-down list and click Apply 
  • Next, open Command Prompt and execute the command gpupdate in it

Thus, doing so will fix the CredSSP Encryption Oracle Remediation error. After the connection termination, you should undo the security setting.

Method 2: Use the Registry Editor

If you have Windows 10 Home Version, the Local Group Policy editor wouldn’t have worked for you. Here’s where you have Registry Editor for the same effect.

  • Press the Win+R keys, type regedit, and press the Enter key
