To fix an authentication error that occurred in Remote Desktop, you can follow these steps:
1. Open the Group Policy Editor by typing “gpedit.msc” in the Run dialog box or search bar and pressing Enter.
2. In the Group Policy Editor, navigate to “Computer Configuration” and expand “Administrative Templates.”
3. Expand “Windows Components,” then “Remote Desktop Services,” and further expand “Remote Desktop Session Host.”
4. Click on the “Security” folder.
5. In the right-hand pane, locate the policy named “Require user authentication for remote connections by using Network Level Authentication.”
6. Double-click on this policy to open its settings.
7. Select the “Disabled” option and click “OK” to save the changes.
By disabling this policy, you are allowing remote connections to bypass Network Level Authentication, which may resolve the authentication error you are experiencing.
It’s important to note that disabling Network Level Authentication may reduce the security of your remote desktop connections. Network Level Authentication provides an extra layer of authentication before establishing a remote connection, ensuring that only authenticated and authorized users can access the system. Disabling it should be done with caution and only in situations where it is necessary for compatibility or troubleshooting purposes.
If you continue to experience authentication errors after disabling Network Level Authentication, there may be other underlying issues causing the problem. In such cases, it is recommended to check the following:
1. Ensure that the username and password you are using to connect to the remote desktop are correct and have the necessary permissions.
2. Verify that the remote desktop server is reachable and not experiencing any network connectivity issues.
3. Check if any firewall or antivirus software is blocking the remote desktop connection.
4. Confirm that the Remote Desktop service is running on the remote server.
5. Update the Remote Desktop client software on the local machine to the latest version.
6. Restart both the local and remote machines to refresh the network settings.
If the problem persists, you may need to seek further assistance from your system administrator or IT support team to diagnose and resolve the authentication error.
