Quick Note

Before you start, please ensure:

  • You have administrator access on your Windows 11 PC. Without this, you cannot make the necessary changes.
  • Your Windows 11 device is updated with the latest system updates to avoid unexpected errors.
  • You understand that disabling Network Level Authentication will reduce the security of your Remote Desktop connection, so only disable it if necessary and when you trust your network environment.
  • Remote Desktop is enabled on your device. You can check this under Settings > System > Remote Desktop.

What is Network Level Authentication (NLA)?

NLA is a security feature that requires users to authenticate before establishing a full Remote Desktop connection. It helps protect your PC from unauthorized access and reduces the risk of attacks.

However, NLA can sometimes cause connection problems, especially if the client device doesn’t support it or if there are network configuration issues. Disabling NLA can help in these cases.

How to Disable NLA on Windows 11: Step-by-Step

Step 1: Open System Properties

First, you need to access the System Properties window where Remote Desktop settings are located.

  1. Press Windows + R on your keyboard to open the Run dialog box.
  2. Type sysdm.cpl and press Enter.
  3. This will open the System Properties window.

Step 2: Navigate to Remote Settings

Once in System Properties:

  1. Click the Remote tab at the top.
  2. Under the section labeled Remote Desktop, you will see options related to Remote Desktop connections.

Step 3: Disable Network Level Authentication

Now, to disable NLA:

  1. Look for the checkbox that says “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)”.
  2. Uncheck this box to disable NLA.
  3. Click Apply, then OK to save your changes.

Disabling this option means your PC will accept Remote Desktop connections without requiring the client to authenticate first, which can help fix connection issues.

Step 4: Verify Remote Desktop is Enabled

Make sure Remote Desktop is enabled:

  1. Open Settings by pressing Windows + I.
  2. Go to System > Remote Desktop.
  3. Ensure the toggle for Remote Desktop is switched on.

  • Try connecting remotely again to see if the issue is resolved.

Alternative Method: Disable NLA Using Registry Editor

If you prefer or need to use the Windows Registry to disable NLA, here’s how:

  1. Press Windows + R, type regedit, and press Enter.
  2. If prompted by User Account Control, click Yes.
  3. Navigate to the following path:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-Tcp
  4. In the right pane, find the value named UserAuthentication.
  5. Double-click it and change its value data from 1 to 0.
  6. Click OK and close the Registry Editor.
  7. Restart your computer to apply changes.

Note: Editing the registry incorrectly can cause serious system issues. Always back up your registry before making changes.

FAQs

Is disabling NLA safe?

Disabling NLA reduces the security of your Remote Desktop connection because it allows unauthenticated connection attempts. Use this only if you are on a trusted network and understand the risks.

Why am I still unable to connect after disabling NLA?

There could be other issues such as firewall settings, network problems, or Remote Desktop service issues. Ensure Remote Desktop is enabled, your firewall allows Remote Desktop connections, and your network is configured correctly.

Can I re-enable NLA later?

Yes, you can re-enable it anytime by following the same steps and checking the NLA box again, or by setting the registry value back to 1.

Do client devices need to support NLA?

Yes, clients must support NLA if it is enabled on the host. Older Remote Desktop clients might not support NLA, causing connection failures.

When Nothing Works

If disabling NLA doesn’t solve your Remote Desktop connection problems, consider these final options:

  • Check Windows Firewall settings to allow Remote Desktop connections.
  • Verify your network connection and router settings.
  • Update your Windows 11 system and Remote Desktop client software to the latest versions.
  • Consult the official Microsoft Remote Desktop support page: Microsoft Remote Desktop FAQ.
  • Consider using alternative remote access tools if Remote Desktop continues to fail.

Conclusion

Disabling Network Level Authentication on Windows 11 can be an effective way to fix Remote Desktop connection issues, especially when client compatibility is a problem. This guide has shown you simple, step-by-step methods to disable NLA safely.

Remember to weigh the security implications before disabling NLA and always ensure your network environment is secure. If you continue to experience issues, explore the alternative troubleshooting steps or seek official support.
