Error 0x204: How to fix Remote Desktop Connection issues

Remote Desktop Protocol is a proprietary protocol developed by Microsoft which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software. See the following guides for how to allow saved credentials for RDP connection and Error code 0x4, Session disconnected: Your session ended because of an error, if this keeps happening, contact your system administrator for assistance, We Could not connect to the remote PC with error code 0x204 and make sure the PC is turned on and connected to the network – Part 1, and We could not connect to the remote PC with error code 0x204 and make sure the PC is turned on and connected to the network – Part 2.

The Remote Desktop Connection error 0x204 can be due to various reasons like driver issues, security permission, recently installed hardware, network-related issues, etc.  See the following guides to resolve some mere Remote Desktop Connection issues.

Issues address in the attached troubleshooting guides are as follow
– Ensure the device is truly turned on.
– Network connectivity issue ( Ensure you enter the right IP Address) and ensure you are on the same network.

Note: Despite ensuring the following details are met, you may still not be able to initiate remote desktop connection to a remote device. Kindly follow the steps below to ensure the RDP issue is resolved.

Windows Firewall or Anti-Virus Agent: This is one of the areas you should look at to resolve Remote Desktop problems. If Remote Desktop is blocked by Firewall, you will NEVER be able to connect to the remote device. As you can see below, Norton 360 currently manages these settings and not Windows Defender Firewall.

Since I am using Norton 360, I will click on Norton 360 to open it
– Click on settings and under Traffic rules
– Uncheck the Active button “for the Default Block Remote Desktop”
– Click on modify to to change the block state to “allow” state and
– Click on apply to complete this setup.

Note: If you do not have an external Anti-Virus solution, Remote Desktop is not enabled in Firewall by default, so if you are running Remote Desktop for the first time, you have to allow it through the firewall. 

To do this, follow the steps below.
- Launch the Control Pannel (You can also use the Windows Settings)
- Click on "Allow an App through the firewall" 

This will open up the “Allowed Apps” window as shown below
– Click on Change Settings in order to be able to make the changes
– And click on OK to complete the configuration.

Not a domain joined device
For a device that is connected to a domain and you wish to permit RDP, simply check the button under "Domain" as shown below.
Domain Joined device

Ensure Remote Connection is allowed: To enable remote desktop connection, launch the Windows Control Panel as follow
– Click on “Allow remote Access”
Note; You can also search from the Windows search button for “remote settings”

This will open the System Prepares Windows.
– Check Allow remote connections to this computer and
– Click OK to save changes.

Note: In this window above, you can restrict RDP connection to selected users.

Default Block settings was enabled in Norton. Once I disabled this setting Remote Desktop started working for me.
