0x204 remote desktop ошибка mac os

Reading time: 6 Minutes

Access your Windows PC on another device using Remote Desktop Protocol, a Microsoft proprietary protocol that provides a graphical interface to connect to a different computer via a network connection. However, some Mac users have reported getting the Remote Desktop error code 0x204 when connecting to their Windows PC using a Mac. Although Remote Desktop is a great tool, things don’t always work smoothly.

What Is the Mac Error Code 0x204 Remote Desktop?

This error message pops up whenever a user is trying to access their Windows computers from a device running macOS. When this happens, you will see this error message on your Mac’s screen:

We couldn’t connect to the remote PC. Make sure the PC is turned on and connected to the network, and that remote access is enabled.

Error code: 0x204

This error is triggered whenever you try to use your Mac to access your Windows computer using the Remote Desktop client. The user is not able to connect remotely to the target computer and gets this error instead.

Causes of Remote Desktop Error Code 0x204 on Mac

In most cases, the Mac error code 0x204 Remote Desktop problem happens when the Remote Desktop Protocol is not turned on in the Windows machine you are trying to access. This is important because this software is what initiates the connection between the two devices, and without it, you won’t be able to connect to your PC. The easiest way to fix this is by enabling the Remote Desktop Protocol manually.

Another reason why you might be getting this issue is because of your Firewall since it is in charge of monitoring all incoming connections to your Mac. If you need to connect to your PC multiple times, then you need to establish an exclusion for your Firewall to allow Remote Desktop. If it is a one-time occasion, you might consider temporarily disabling your Firewall and security software. However, remember to turn it back on immediately after the activity to ensure your device remains protected.

There are instances when the Mac error code 0x204 Remote Desktop occurs because of corrupted temporary files located in the Group Containers folder, preventing the client from functioning properly. Deleting the UBF8T346G9.com.microsoft.rdc folder should help resolve the error.

Remote Desktop Error Code 0x204 on Mac Solution

If you’re getting this error when using RDP to connect to your Windows PC, you can give the solutions below a try:

Fix #1: Turn On the Remote Desktop Protocol on Your PC.

If Remote Desktop is not enabled on your Windows computer, you won’t be able to connect to it no matter what you do. This is the first thing you need to check when you’re trying to remote access your Windows PC. This is usually the case if you’re trying to connect to your PC via Remote Desktop Protocol and you get the same error no matter what device you use.

If this is the case, you need to enable Remote Desktop Protocol on the Windows computer you want to access. Here are the steps you can follow:

1. On your Windows computer, press Windows + R to launch the Run dialog.
2. In the dialog box, type in SystemPropertiesRemote.exe and press Enter. This should open the System Properties window.
3. Click Yes when you’re prompted by the UAC to grant administrative privileges.
4. In the System Properties window, click on the Remote tab.
5. Scroll down to the Remote Desktop section and tick off Allow remote connections to this computer.
6. If you’re trying to connect to the PC using a different network, uncheck Allow connections only from computers running Remote Desktop with Network Level Authentication.
7. Click Apply to save the changes and close the window.

Go back to your Mac then try to connect this time using the same Remote Desktop protocol and see if the error has been resolved.

Fix #2: Allow Remote Desktop through the Windows Firewall.

By default, Windows Firewall is not set up to whitelist the Remote Desktop Protocol. Hence, your Firewall will try to stop the connection every time you try to connect. So if you want to access your Windows files from other devices, you need to modify your firewall settings to allow Remote Desktop and Remote Desktop (Websocket).

To do this:

1. On your Windows computer, press Windows + R to launch the Run dialog.
2. In the dialog box, type in firewall.cpl and press Enter. This should open the Windows Firewall settings menu.
3. Click Yes when you’re prompted by the UAC to grant administrative privileges.
4. In the Windows Defender Firewall settings, click Allow an app or feature through Windows Defender Firewall from the left menu.
5. In the Allowed apps window, click the Change settings button to change the list of allowed apps.
6. Scroll down to find Remote Desktop and Remote Desktop (WebSocket), then tick off the Private and Public boxes.
7. Hit OK to save the changes.

Restart your computer and check if you are now able to connect via Remote Desktop Protocol.

Fix #3: Disable Third-Party Antivirus.

Sometimes this error is caused by the overactive security software, so you need to disable it temporarily to let the connection go through. You can use the security software’s dashboard to pause its protection while you’re trying to troubleshoot this error. Once disabled, try connecting via Remote Desktop Protocol and see if you’ll be successful this time. If you’re able to connect with your antivirus disabled, it may be blocking the Remote Desktop Protocol. Consider modifying its settings to allow this connection, rather than disabling it entirely or switching to a different security program. You should also make it a habit to clean up junk files on your PC regularly using a PC cleaner to avoid errors like this.

Once you’re done troubleshooting, it’s crucial to re-enable your security software immediately to maintain your device’s protection against potential threats.

Fix #4: Use the Remote Assistance Invitation.

Creating an offline invitation using Remote Assistance on your Windows computer is another workaround for this error. This can be a useful approach if the issue relates to specific network port restrictions. To do this:

1. On your Windows computer, press Windows + R to launch the Run dialog.
2. In the dialog box, type in msra.exe and press Enter. This should open the Windows Remote Assistance wizard.
3. Click Yes when you’re prompted by the UAC to grant administrative privileges.
4. Next, click on Invite someone you trust to help you.
5. Choose Save this invitation as a file.

On your Mac, open the invitation that you have created using Remote Assistance and check if the error code 0x204 no longer appears.

Fix #5: Delete the Removing Remote Desktop Temp Folder on Your Mac.

If you are getting the error code 0x204 only on your Mac, then it is possible that the files related to the Remote Desktop Protocol have been corrupted, preventing you from establishing a connection with your Windows PC. Deleting the temporary folder should clear this issue. To do this:

1. Quit the Remote Desktop client on your Mac by pressing Command + Q.
2. Click on the Finder icon on the Dock.
3. In the search box on the upper-right corner of the Finder window, type in group containers, then press Enter.
4. Click on the Group Containers folder from the search results.
5. Inside the folder, look for the UBF8T346G9.com.microsoft.rdc file and drag it to the Trash.
6. Restart your Mac and see if Remote Desktop is now working properly.

Summary

Remote Desktop is a cool feature that allows you to copy files between devices running different OS, without using a USB or an external drive. It also allows you to manage apps and control the device remotely through the Remote Desktop Protocol. If for some reason, you can’t connect to your Windows PC using your Mac, you can refer to the steps above and find the solution that works for you.

Some users that are trying to connect to a Windows computer from a Mac, Android or a different OS have been getting the Error Code 0x204 when trying to use the Remote Desktop protocol. Although Remote Desktop is a robust tool that allows users to connect to a PC and get their access to apps, files, and network resources, sometimes things aren’t working as they should.

One of the most common problems that will trigger the Error Code 0x204 is an instance in which the Remote Desktop Protocol is not enabled on the Windows machine. In this case, you can fix the issue by enabling it manually via the System Properties screen and by allowing Network Level connections.

However, this can also be caused by your firewall (since the process used by remote desktop is exploited by a lot of malware). In order to fix the issue, in this case, you need to establish an exclusion rule, disable the real-time protection or uninstall the 3rd party security suite altogether.

In some cases, the problem can occur due to some temporary files that are stored inside the Group Containers folder. If this scenario is applicable, you can fix the issue by deleting the UBF8T346G9.com.microsoft.rdc folder.

Method 1: Enable the Remote Desktop Protocol (on the Windows Machine)

One of the most common causes that will cause the Error Code 0x204 when trying to access files from a Windows OS using the Remote Desktop protocol is by far an instance in which the Remote Desktop functionality is not enabled inside the System Properties screen.

This should be your first troubleshooting step if you tried connecting using the Remote Desktop protocol using multiple devices and all of them produced the same issue.

Here’s a step by step guide on ensuring that the Remote Desktop Protocol is enabled on the Windows machine that you which to access files from:

Note: The steps below are universal and should work regardless of the Windows version that you are using on the host machine.

1. Press Windows key + R to open up a Run dialog box. Next, inside the text box, type ‘SystemPropertiesRemote.exe’ and press Enter to open up the System Properties screen.

   Note: When you’re prompted by the UAC (User Account Control), click Yes to grant administrative privileges.

2. Once you’re inside the System Properties screen, start by checking if you’re already inside the Remote tab. If you are, go to the Remote Desktop section and change the toggle to Allow remote connections to this computer.

   Note: If you are trying to connect to the computer from a different network, you will also need to uncheck the box associated with ‘Allow connections only from computers running Remote Desktop with Network Level Authentication’
   

   

3. Click Apply to save the changes, then attempt to connect using the same Remote Desktop protocol once again and see if the issue is now resolved.

In case the issue is still not resolved, move down to the next potential fix below.

Method 2: Allowing Remote Deskstop through Windows Firewall

Keep in mind that by default, Windows Firewall is not configured to have the Remote Desktop protocol whitelisted.

So if you want to use Remote Desktop to make your files accessible by other machines, you will need to modify the default security settings in order to allow Remote Dekstop and Remote Desktop (Websocket) via the Allowed apps menu of the Windows Firewall settings.

This needs to be done regardless of which Windows version you’re using.

Important: If you’re using a 3rd party firewall suite, the steps below will not apply. In this case, you will need to look for specific steps that will allow you to whitelist the Remote Desktop protocol.

Here’s a quick guide on how to allow the Remote Desktop Protocol to communicate with other devices in this network:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘firewall.cpl’ and press Enter in order to open up the Windows Firewall settings menu.

   Note: If you are prompted by the UAC (User Account Control), click Yes to grant administrative privileges.

2. Once you’re inside the Windows Defender Firewall settings, click on Allow an app or feature through Windows Defender Firewall from the left-hand side menu.
3. Inside the Allowed apps window, start by clicking on Change settings button (top-right section) in order to be able to modify the list of allowed apps.
4. Scroll down through the list of allowed items and enable the Private & Public box associated with Remote Desktop.
5. Next, do the same thing with the entry named Remote Desktop (WebSocket) and press Ok to save the changes.
6. Restart your Windows machine and attempt to connect to it using the Remote Desktop protocol once the next startup sequence is complete.

In case the problem is still not resolved and you’re still encountering the same Error Code 0x204, move down to the next potential fix below.

Method 3: Disabling your 3rd party AV (if applicable)

As it turns out, there are a lot of cases with users that are encountering this issue with 3rd party security suites. McAfee Internet Security is the most common 3rd party suite that is known to facilitate the Error Code 0x204.

What is most likely happening, is the 3rd party AV triggers a false-positive and threats the port used by the Remote Desktop protocol as a malicious attempt to access your files from a distance.

In case this scenario is applicable to your current situation, you should be able to fix the issues imply by disabling the real-time protection of your 3rd party AV suite. But keep in mind that the steps of doing this are specific depending on which AV you’re using.

But in most cases, you will be able to disable the real-time protection (active shields) directly from the taskbar menu. To do this, simply right-click on the taskbar menu icon and look for an option that disables the real-time protection.

In case you’ve done this to no avail or you’re using a 3rd party firewall suite, move down to the next potential fix below.

Method 4: Uninstalling 3rd party Firewall (if applicable)

In case you’re using a 3rd party firewall, disabling it or preventing it from running will not make a difference since the same security suites will remain in place. If the issue is caused by a 3rd party firewall, the only way to fix it is to establish a whitelisting rule that excludes the Remote Desktop from the list of analyzed processes.

But keep in mind that the steps of doing so are very different from tool to tool.

If your AV has no option of adding exceptions, the only viable fix is to uninstall the entire security tool altogether and ensure that there are no remnant files that will still keep that port blocked.

In case you want to follow through with this method, here’s a step by step guide on uninstalling your third party firewall:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ and press Enter to open up the Programs and Files menu.
2. Once you manage to get inside the Programs and Features menu, scroll down through the list of installed applications and locate the entry associated with your 3rd party firewall. When you see it, right-click on it and choose Uninstall from the context menu.
3. Inside the uninstallation screen, follow the on-screen prompts to complete the process, then restart your computer.
4. After the next startup is complete, completely uninstall the program to ensure that you’re not leaving behind any remnant files that might still cause this behavior.
5. Once you’ve ensured that your 3rd party firewall is removed, attempt to reconnect using the Remote Desktop protocol and see if the Error Code 0x204 issue has been resolved.

In case the same problem is persisting, move down to the next potential fix below.

Method 5: Using the Remote Assistance invitation

As it turns out, some users have been able to fix the issue by creating an offline invitation using the Windows Remote Assistance utility and opening that on the machine that is unable to connect using the Windows Remote Protocol.

This operation will end up bypassing every potentially blocked port that might be triggering the Error Code 0x204 issue by using an offline invitation.

Here’s a quick guide on how to create this Remote assistance invitation:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘msra.exe’ in the text box and press Enter to open up the Windows Remote Assistance wizard.

   Note: If you’re prompted by the UAC (User Account Control) prompt, click Yes to grant administrative privileges.
2. Once you’re inside the Windows Remote Assistant wizard, click on Invite someone you trust to help you.
3. From the next screen, click on Save this invitation as a file.

   Note: You can go for a different option if you find it easier (either attach the invitation with an email program or use Easy Connect)

4. Open the invitation that you previously created on the machine that you’re having trouble connecting with and see if the problem is resolved. Once the invitation is opened, every necessary port should be opened and the Error Code 0x204 should no longer occur.

In case the same problem is still persisting, move down to the next potential fix below.

Method 6: Removing the temp folder of Remote Dekstop (MAC Only)

If none of the methods above have worked and you’re only encountering the issue with OSX, it’s very likely that the temp folder used by the Mac Remote Desktop application contains corrupted files that are preventing the connection from being established.

In case this scenario is applicable to your current situation, you can fix the issue by removing the temp folder from the Group Container’s folder. Here’s a quick guide on how to do this:

1. Ensure the Remote Desktop Program on Mac is completely closed.
2. Click on your Finder icon (bottom-left corner of the screen).
3. Inside the Finder app, use the search function to search for ‘group containers‘, then press Return to retrieve the results.
4. Once you’re inside the group containers folder, delete the UBF8T346G9.com.microsoft.rdc entry by right-clicking and choosing Move to bin from the context menu.
5. Restart your Mac computer and see if the issue is resolved at the next startup.
