Among the support options that we have as administrators we have a classic one that is integrated into the Windows 10 operating system itself and is the remote desktop which allows us to connect to a team remotely to provide support, management and collaborate with the user. In this way we will avoid having to go physically to the place since this implies saving time and money:
In some situations the remote desktop in Windows 10 can present errors such as:
- It does not connect correctly with the remote computer
- Remote Desktop Doesn’t Work After Windows 10 System Has Been Updated
- Remote desktop credentials are not recognized
- Network errors
- Certificate errors
With this tutorial we will give you a series of tips so that you can solve problems related to Remote Desktop access.
Check internet connection
The first and most basic step is to check that our Internet connection is correct, we can check this in various ways such as:
- Accessing a browser and visiting a website.
- Checking the network status on the taskbar.
- Checking the connections in the modem or router.
1. How to check Windows 10 Remote Desktop permissions
Remote Desktop is configured by default with a security policy focused on optimizing and improving the security of the computer, preventing external attackers from accessing it.
We can validate that the remote access permissions are well configured, for this we will go to the following route:
- Control Panel
- Security system
There we click on the line “Advanced system configuration” and in the pop-up window we will go to the “Remote access” tab. There we must validate that the “Allow Remote Assistance connections to this computer” box is active:
If it is not, we activate it and click on Apply and OK to confirm the changes.
2. How to validate the Windows 10 Firewall settings
The Windows 10 Firewall is designed in a series of rules (input and output) which allow everything that happens on the computer to have the necessary permissions. Thus, if any port or program is restricted, it will not be able to send or receive data, since Remote Desktop requires an external connection, it is possible that Windows Firewall prevents its connectivity.
We must validate this from the following path:
- Control Panel
- Security system
- Windows Defender Firewall
We will click on “Allow an application or a feature through Windows Defender Firewall”, we will see the following:
We click on the “Change settings” button
Next we locate “Remote Desktop” and select the type of network to allow access. We click OK to save the changes.
It is important to clarify that by default Remote Desktop is not enabled in Windows 10 Firewall.
3. How to remove credentials from Windows 10 Remote Desktop
Connectivity errors may be due to failures with current credentials, so clearing saved credentials and entering new ones can help correct Remote Desktop connection problem.
To do this, we access the Remote Desktop utility from the Start menu and the application will go to the “Advanced Options” tab. We click on the “Settings” button
In the displayed window we must delete the credentials in the “Login Configuration” section:
4. How to configure Windows 10 screen scaling
Because the remote connection makes use of hardware resources, it is possible, in some cases, that screen scaling is the cause of Remote Desktop connection errors.
To correct this we will go to the Start / Settings menu and there we go to the System category and on Screen we will click on the line “Advanced scale settings”:
In the next window we can make the adjustments that we consider necessary.
5. How to edit Windows 10 registries
This is a sore point since a bad configuration can lead to system performance errors. Therefore, it is ideal to create a backup as well as create a restore point.
Next we will use the Windows + R keys and execute the command “regedit” and we will go to the following path:
HKEY_CURRENT_USER \ Software \ Microsoft \ Terminal Server Client
There we will right click on a free place and select “New / DWORD Value (32 bits)”:
This value will be called “RDGClientTransport”:
Next we will double click on this DWORD value and set the number 1 in the Value information field. Click on accept and we can close the Windows 10 registry editor.
6. How to add the IP and computer name in the Windows hosts file
The hosts file allows you to specify some computer connection parameters, both enabling and restricting them.
For this process we will go to the following route:
C: \ Windows \ System32 \ drivers \ etc
There we right click on the hosts file and choose the editor with which it has to be modified:
Once open, we enter the IP and name of the remote computer. We save the changes to complete the process.
7. How to check Remote Desktop ports in Windows 10
By default, Windows 10 Remote Desktop uses port 3389 for outgoing connections. If this port is closed it will be impossible for the connection to be correct. We can use the netstat command to validate the status of port 3389:
8. How to edit the type of network used in Windows 10
We know that Windows allows us to manage a public or private network in the system, each with its own characteristics, but the private network will always be the safest to use.
Therefore, if we use a public network, we can make it private to optimize the use permissions. For this we will go to the following route. We click on the line “Change connection properties”
- Network and Internet
Then we activate the “Private” box:
9. Using a third-party application to fix remote desktop doesn’t work and won’t connect Windows 10
If finally nothing solves the Remote Desktop connectivity, we can make use of an application that handles the same functionality, we can use some such as:
- Remote Desktop
- Chrome Remote Desktop
Thus, we can use any of these solutions to allow the support and use of Remote Desktop to be as complete as possible and we are not restricted for any reason to provide or receive help at any time.
