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:

  • It does not connect correctly with the remote computer
  • Remote Desktop Doesn’t Work After Windows 10 System Has Been Updated

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.

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.

Step 1

We can validate that the remote access permissions are well configured, for this we will go to the following route:

  • Control Panel
  • Security system
  • System

Step 2

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.

Step 1

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:

Step 2

We click on the “Change settings” button

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.

Step 1

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

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.

Step 1

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)”:

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.

Step 1

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”

  • Start
  • Setting
  • Network and Internet

Step 2

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:

  • TeamViewer
  • Splashtop
  • 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.
