Fixing Oracle Remediation Error in Remote Desktop Connection

Sanjana Kumari


Remote Desktop Connection (RDC) is a valuable feature that allows users to connect to a remote computer and access its resources as if they were sitting in front of it. However, sometimes users encounter the “CredSSP Encryption Oracle Remediation” error while trying to establish a remote desktop connection. This error can be frustrating and hinder remote work, but fret not! In this article, we will explore the causes of the CredSSP error and provide effective solutions to resolve it.

Understanding the CredSSP Encryption Oracle Remediation Error

The CredSSP error is an authentication-related issue that arises when the client and server fail to negotiate the use of CredSSP (Credential Security Support Provider) during the connection process. CredSSP is a security protocol that helps protect credentials when authenticating via the Remote Desktop Protocol (RDP). When this protocol fails to establish a secure connection, the CredSSP error occurs.

Causes of the CredSSP Error

Several factors can contribute to the CredSSP error, ranging from outdated software to misconfigured settings. Some common causes include:

  1. Outdated Remote Desktop Client: Using an older version of the Remote Desktop client might lead to compatibility issues with the server.
  2. Group Policy Settings: Certain Group Policy configurations may prevent the successful negotiation of CredSSP during the authentication process.
  3. Registry Entries: Incorrect or misconfigured registry entries can disrupt the CredSSP process.
  4. Credential Delegation: Improperly configured credential delegation settings can trigger the error.

Impact on Remote Desktop Connection

The CredSSP error can have significant implications for users relying on Remote Desktop Connection. It may result in the inability to establish connections to remote systems, disrupting workflow and productivity.

Common Scenarios of Encounter

The CredSSP error can manifest in various scenarios, such as when trying to connect to a remote workstation, server, or virtual machine. Additionally, it may occur when accessing remote resources through applications like PowerShell or File Explorer.

Troubleshooting Methods

To resolve the CredSSP error, several troubleshooting methods can be employed:

  1. Update Remote Desktop Client: Ensuring that the Remote Desktop client is up-to-date can resolve compatibility issues and patch known vulnerabilities.
  2. Modify Group Policy Settings: Adjusting Group Policy settings to permit CredSSP negotiation can address the error.
  3. Editing Registry Entries: Correcting registry entries related to CredSSP can help establish a secure connection.
  4. Adjusting Credential Delegation: Modifying credential delegation settings to the appropriate level can resolve the error.

Common Scenarios Leading to the Error:

Several factors can trigger the CredSSP Encryption Oracle Remediation Error. Understanding these factors can help us troubleshoot the issue effectively. The common scenarios include:

  1. Outdated Windows versions: Using older Windows operating systems that lack essential security updates can trigger the CredSSP error.

  2. Network and firewall issues: In some cases, network or firewall configurations can interfere with the CredSSP protocol, resulting in the error.

  3. Misconfigured system settings: Incorrect settings related to user authentication or encryption can cause the CredSSP Encryption Oracle Remediation Error.

How to Fix Encryption Oracle remediation

If an Encryption Oracle Remediation policy setting on the server or client prevents an insecure RDP connection from being established, this error will appear. This parameter determines whether an insecure RDP is permitted as well as how an RDP session utilising CredSSP should be built.

NOTE : Every step is done on the local computer.

The most typical situation is when the CredSSP update is implemented on the client and the Encryption Oracle Remediation policy setting forbids an insecure RDP connection to a server that is not running the CredSSP update.

STEP 1: Click the Start button, enter run, and then click OK.

STEP 2: Enter gpedit.msc, and then in the left panel, select Computer Configuration – Administrative Templates – System – Credentials Delegation.

STEP 3: When you double-click on the Encryption Oracle Remediation policy, set the Protection Level to Vulnerable, Enable the policy, and then click Apply.

STEP 4 : CMD, followed by gpupdate, should be entered after typing CMD in the Window search bar.

NOTE : Since the Local Group Policy Editor is absent from Windows 10 Home, you can still alter the registry.

a. In the search bar, type CMD and click “Open with right click as administrator”

b. Enter REG and copy/paste the following command to add a registry value. AllowEncryptionOracle /t REG_DWORD /d 2 ADD HKLMSoftwareMicrosoftWindowsCurrentVersionPoliciesSystemCredSSPParameters
