This option represents a more secure authentication method that can better protect your computer.

Solution 2: Make sure Remote Desktop is allowed through your software firewall

Sometimes, the error occurs because remote desktop connections are not allowed through the Windows Firewall or any other security software you might be using. In order to check this:

  1. Navigate to Control Panel and go to System and Security
  2. Go to Allow an app through Windows Firewall, located under Windows Defender Firewallallow an app through windows firewall
  3. Locate Remote Desktop and tick to allow it for both private and public networksk

Solution 3: Map the port for Remote Desktop connections

Another step that should be taken into consideration, if your remote sessions are through internet, is making sure that your router has been configured to forward he remote desktop port (3389 by default) to the correct computer on your network.

Since routers have different interfaces, it is almost impossible to give you specific instructions but here are some basic steps that could guide you through the process:

  1. Get the IP address of the computer you want to connect to. The simplest way to do that is to open Command Prompt and type ipconfigcommand-prompt-ip-adress
  2. Log into your router and locate the Port Forwarding section. Into that section you should forward TCP port 3389 to the IP address located previously

Also, please pay attention that exposing the Remote Desktop server directly to the internet, generates risks: malware, automated hacking, etc. So you should make sure that you use strong passwords and install a VPN.

Another suggestion regarding security could be to change the RDP listening port from the 3389 default to another high port number in the dynamic range.

Solution 4: Check if new hardware/ drivers have been installed

Error 0x204 could also occur if you recently added hardware to your computer or you have installed new or updated drivers to your computer. If this happened, you could try to:

  1. Run hardware diagnosis supplied by the system manufacturer to determine which hardware component failed
  2. Remove or replace the newly installed driver.
