Remote Desktop is an easy-to-use and effective option that allows you to control your Windows 10 machine from another computer. Thanks to this handy tool, you can connect to your PC and have access to your apps, files and network resources, which is undoubtedly awesome. That said, things do not always go that smoothly: you may try to use Remote Desktop only to see the error code 0x204 on your screen. We agree that such a failure is pretty discouraging. Nevertheless, there is no need to get all worked up about that. Just keep reading this article to know how to fix the Remote Desktop connection error 0x204.

What is the Remote Desktop connection error code 0x204 on Windows 10?

Frankly, since multiple issues can bring about the error code in question, there is little need for digging really deep into the origins and definition of the problem. Most often, the 0x204 trouble stems from antiquated driver software or incorrect connection or security settings. What you finally encounter is the failure of your remote connection, which is something that we can describe as a perfectly fixable nuisance.

To help you enjoy the Remote Desktop connection feature in Windows 10, we have collected a whole list of proven solutions to the cases described above. What you should do is work your way down until you arrive at what is capable of eliminating the error code 204.

How to fix the Remote Desktop connection error 0x204?

Tip 1. Update all your drivers

To begin with, you should never lose sight of the fact that out-of-date drivers are a serious threat to the stability and performance of your Windows 10 computer. In the 0x204 scenario, the most likely culprit is your network adapter driver; however, that is not necessarily the case. What we are driving at is that you will lose nothing by checking all your drivers – this way you can be 100 % sure you haven’t missed the one that is actually causing the malfunction.

You are free to perform that quest manually, but keep in mind that such an approach is ridiculously taxing, not to mention the fact that you may accidentally install the wrong software and thus complicate the matter even further.

Another option is to use Device Manager to automate the search, but updating drivers is still no easy task even with this built-in utility involved:

  1. Right-click on the Windows logo icon.
  2. Select Device Manager.
  3. Expand any device section by clicking on it.
  4. Right-click on any of the devices exposed.
  5. Select Update Driver.
  6. Select ‘Search automatically for updated driver software’.
  7. Wait until the search is complete.
  8. Agree to install the software that has been found.

You should take the steps above to update driver software for each of your devices. We guess you have realized that this is quite a time-consuming procedure.

Undoubtedly, your best bet in fixing driver software is using a dedicated tool. For example, you can opt for

Auslogics Driver Updater: this product will update all your drivers to their latest manufacturer-recommended versions in just one click.

Tip 2. Enable the Remote Desktop protocol

You should check your remote connection settings to see if your PC can be accessed from another device. To do that, follow the instructions below:

  1. Press the Windows logo key + R shortcut to invoke the Run app.
  2. Once it is up, type SystemPropertiesRemote.exe and press the OK button.
  3. You will be taken to the System Properties menu.
  4. Navigate to the Remote tab.
  5. Move to the Remote Desktop section.
  6. Select ‘Allow remote connections to this computer’.
  7. Check ‘Allow remote connections only from computers running Remote Desktop with Network level authentication (recommended)’.

Click Apply and OK to save your changes and see if your issue has been resolved.

Tip 3. Configure your security settings

Now it is time to make sure your Windows Firewall allows remote desktop connections. Here are the instructions you need to do that:

  1. In your Start Menu, locate Control Panel and enter it.
  2. Proceed to System and Security.
  3. Navigate to Windows Defender Firewall.
  4. Click on the Allow an app through Windows Firewall link.
  5. Locate Remote Desktop and check it.

Hopefully, your issue is no more.

Tip 4. Reset the Remote Desktop connection for your account

Resetting the problematic Remote Desktop connection may prove useful in getting rid of the connection error 0x204. Here is what you should do:

  1. Open the Search app (Windows logo key + S).
  2. Type Remote Desktop and press Enter.
  3. Open the app in question.
  4. Navigate to the Remote Desktop connection you wish to delete.
  5. Click on the icon that looks like three horizontally aligned dots.
  6. Select the Remove option.
  7. Close the Remote Desktop app.

Then open the app again and set up the connection you have deleted previously.

Tip 5. Configure your Port Forwarding settings

To fix the Remote Desktop connection error 0x204 on your Windows 10 PC, you should forward the TCP port 3389. Here is how you can do that:

  1. Open your Command Prompt (to access it, invoke Search and type cmd into the Search bar).
  2. Type ipconfig and hit the Enter button on your keyboard.
  3. Note the IPv4 Address and the Default Gateway information.
  4. Open your web browser.
  5. Type the IPv4 Address of your router.
  6. Sign in to your router.
  7. Look for the Port Forwarding section.
  8. Check if Port Forwarding is enabled. Enable it if it is disabled.
  9. Configure the Port Forwarding settings the following way:
    • Choose any service name you like.
    • Set both Port Range and Local Port as 3389.
    • As for Local IP, paste the IPv4 address of your router.
    • Select TCP in the Protocol section.
  10. Add the new rule and save the changes.

Please bear in mind that your router interface may differ from what is described above, so it is a good idea to check your router manual.

We hope your Remote Desktop issue is over now.
