How to Fix Remote Desktop Error Code 0x204 on Windows and MacOS?

With the rise of remote work, remote desktop connections have become an important part of modern work environments. The 0x204 error is one of the most common problems that users run into. This error, which is often caused by the 0x204 remote desktop protocol, can make it hard for many people to connect stably. In this article, we'll look at what causes this error, what it means, and how to fix it so that your remote desktop experience goes smoothly.

Part 1. Causes of Microsoft Remote Desktop error code 0x204

Navigating the realm of remote desktop connections can sometimes be marred by unexpected errors, with the Microsoft remote desktop 0x204 error being one of the most common culprits. This error, often encountered when Mac users attempt to connect to a Windows PC, can be attributed to a variety of causes. In this section, we'll delve into the primary reasons behind this error, shedding light on its origins and the scenarios in which it most frequently appears.

• Remote Desktop Feature Disabled: One of the most common causes for the 0x204 remote desktop Mac error is quite straightforward: the Remote Desktop feature might not be enabled on the Windows PC that the Mac user is trying to access. For a successful remote desktop connection, both devices need to support and have the feature enabled. If one of the devices isn't running Microsoft's proprietary protocol, the connection attempt will naturally fail.
• Firewall Restrictions: Firewalls, whether third-party or native to the operating system, can sometimes block remote desktop connections. While firewalls are designed to protect machines from malicious connections, they can inadvertently block legitimate remote interoperability as a precaution.
• Antivirus Software: In some scenarios, antivirus software, especially those with network monitoring features, might interpret attempts to set up a remote connection as suspicious activities. This can lead to the triggering of the 0x204 remote desktop Mac error.
• Redundant Temporary Data: On the Mac side, one of the primary reasons for this error can be redundant temporary data generated by the RDP client. Clearing the associated folder from the Group Containers directory on the Mac can sometimes resolve this issue.

It's noteworthy that this error predominantly occurs in a Mac-to-PC connection scenario rather than PC-to-PC, highlighting the unique challenges faced by Mac users when trying to connect to Windows PCs using Remote Desktop.

Part 2. How to Fix Remote Desktop Error Code 0x204 on Windows and Mac

Encountering the Microsoft remote desktop 0x204 error can be a frustrating experience, especially when there's urgent work at hand. However, with the right knowledge and tools, this error can be effectively addressed and resolved. In this segment, we'll walk you through a comprehensive guide detailing step-by-step solutions to troubleshoot and rectify this error, ensuring a smooth remote desktop experience across both Windows and Mac platforms.

Solution 1: Enable Remote Desktop on Windows

One of the primary reasons for the RDP 0x204 error, especially when trying to establish a connection from a Mac to a Windows PC, is that the Remote Desktop feature might not be enabled on the Windows machine. To enable it:

• Press the Windows+R keys simultaneously on the PC you are trying to connect to. This will open the Run box.
• Type SystemPropertiesRemote.exe and hit Enter.

• Click the Remote tab and ensure that there is a checkmark next to “Allow Remote Assistance connections to this computer.”

• Click the Apply button to save the changes.

Solution 2: Allowing Remote Desktop through Windows Firewall

By default, Windows Firewall might not have the Remote Desktop protocol allowed. To allow it:

• Press the Windows key + R to open the Run dialog box.
• Type firewall.cpl and press Enter to open the Windows Firewall settings.

• Click on "Allow an app or feature through Windows Defender Firewall."

• Find items named “Remote Assistance” and “Remote Desktop,” and ensure they are allowed.

Solution 3: Connect to Windows with IP Address on Mac

Instead of using the computer name, try connecting using the IP address of the Windows machine.

Solution 4: Delete Remote Desktop Temporary Files on the Mac

Redundant temporary data generated by the RDP client on Mac can sometimes cause the error. To resolve:

• Navigate to the Group Containers directory on your Mac.

• Delete the folder named UBF8T346G9.com.microsoft.rdc.

Solution 5: Using the Remote Assistance Invitation

On the Windows machine, create a Remote Assistance invitation and share it with the Mac user. This can sometimes bypass the error.

Solution 6: Disabling Your 3rd Party Antivirus (if applicable)

Some antivirus software, especially those with network monitoring features, might block the RDP connection. Temporarily turn off the antivirus and try connecting again.

Solution 7: Uninstalling 3rd Party Firewall (if applicable)

If you're using a third-party firewall on the Windows machine, it might be blocking the RDP connection. Consider uninstalling it or setting up exclusions for the RDP protocol.
