When working with domain-controlled systems when trying to remote access computers, users have reported the following error message: “The remote computer you want to connect requires network-level authentication (NLA); however, your Windows domain controller is unable to be reached to carry out NLA.

If you are the admin on the computer that is remote, then you may disable NLA through the options available on the remote tab in the System Properties dialog box.

Cause

The reason for the error is that the domain’s controller is unable to be reached, so network-level authentication is not completed. The error was discovered even after the Network Level Authentication was turned on.

The best way to address the issue is to disable the Network Level Authentication completely. Although the NLA offers additional security, perhaps we are stuck with this.

Before implementing these suggestions, it is important to back up your files and create an exact copy of your registry. Ensure there aren’t any running tasks on either PC or computer before continuing.

Fix 1: Disable NLA through Properties

The Network Level Authentication feature is beneficial. It adds additional security, lets you bring an administrator of networks, and determines who can access which system by selecting a single box.

If you decide to do this, check the RDP client is up-to-date and that the destination is domain authenticated.

It should also be possible to view the domain controller. We’ll go via our Remote Desktop Setting route and make it simple. If this does not work, we’ve also provided alternative solutions.

• Use Windows + R Enter “sysdm.cpl” and then press Enter. You’ll be in the system properties.
• Click on the Remote tab, and then remove the checkmark “Allow the connection only to computers that run Remote Desktop using Network Level Security (recommended)“.
• Press Apply to save changes and then exit. Then try connecting to the remote computer once more and see if the issue has been resolved.

Fix 2: Disable NLA through Registry

This technique is also useful even if you need help to complete the first step for some reason. But be aware that this may require you to reboot your computer fully and could cause disruption if you run a production server.

Be sure to back up all your work, and commit to anything that remains within the stage environment.

• Click Windows + R, type “regedit” into the dialogue box, and then hit Enter to start the editor for the registry.
• In your registry editor, select File > Connect Network Registry. Enter the information of the remote computer, and attempt to connect.
• After you have connected, go to the following path for your files:

Pro Tip: If you are experiencing an issue with your PC or notebook, look into Restore Repair, which can scan the repositories for damaged and lost files. It works in the majority of situations in which the issue arises due to a corrupted system.

• Then, change the values below to the number 0.
• Then, navigate to PowerShell and run the command

Fix 3: Disabling the use of PowerShell

One of my favourite ways to disable NLA without going into any details is to disable it with this PowerShell remote command. PowerShell lets you tap into the remote computer, and after identifying the machine, we can run the commands that disable the NLA.

• Start PowerShell on your PC using Windows + S type “Powershell” in the dialogue box, then right-click the result and choose “Run with administrator privileges“.
• After you have logged into PowerShell, Execute these commands:

$TargetMachine = "Target-Machine-Name"

Fix 4: Utilizing the Group Policy Editor

Another method for disabling the NLA is to use an editor for group policies. This is a good option for those who want to disable it completely.

Note that GPO Editor can be an extremely effective tool, and changing values you need to be aware of could make your computer unusable. Be sure to take backups of all values before you begin.

• Click Windows + R Enter “gpedit.msc” into the dialogue box, then press Enter.
• After you have logged into the group policy editor, go to the following route:

Microsoft Windows > Computer Configuration, Administrative Templates Desktop Services > Remote Desktop Session Host > Security.

• Then search for ‘Require authenticated users to connect remotely, using Network Level Authentication and disabling it.
• Following this step, you can check if the error is fixed.

Take note that even after all of these steps, if you’re still unable to connect, attempt to remove the computer from your domain and reread it. This will reset all settings and fix it for you.
