How To Enable Telnet On Windows Server 2019

How to Enable Telnet on Windows Server 2019

Enable Telnet On Windows Server 2019 is a client/server application protocol that provides access to virtual terminals of remote systems on LANs or the Internet. It supports bidirectional 8-bit communications.

However, it is rarely used today, as other protocols like SSH encrypt the authentication process and prevent unauthorized users from taking over the system. The telnet service can be enabled on Windows Server by using the Turn Windows features on or off feature.

Enabling Telnet on Windows Server 2019 involves several steps, including installing the Telnet Client feature and enabling the Telnet Server.

Enabling Telnet on Windows Server 2019

Telnet is a protocol that allows you to connect to remote systems over a network. Windows Server 2019 includes the Telnet Client feature, but the Telnet Server feature needs to be installed and configured separately.

1. Open Server Manager:

  • Launch Server Manager by clicking on the “Server Manager” icon in the taskbar, or open it from the Start menu.

2. Accessing the “Manage Roles and Features” Wizard:

  • In Server Manager, click on “Manage” at the top right, and then select “Add Roles and Features” from the drop-down menu.

3. Starting the Installation Process:

  • Click “Next” on the “Before you begin” page of the wizard.

4. Selecting Installation Type:

  • Choose “Role-based or feature-based installation” and click “Next.”

5. Selecting the Target Server:

  • Ensure that your Windows Server 2019 is selected, and click “Next.”

6. Choosing Server Roles:

  • In the “Select server roles” section, scroll down and find “Telnet Server.” Check the box next to it.

7. Installing Additional Features:

  • A pop-up window may appear asking you to add additional features. Click “Add Features” to include the required components for the Telnet Server. Then click “Next.”

8. Confirming Installation:

  • Review your selections and click “Install” to start the installation process.

9. Completing the Installation:

  • Once the installation is complete, you will see a summary. Click “Close” to exit the wizard.

10. Verifying Telnet Server Installation:

javascript
- To ensure that Telnet Server has been successfully installed, open a PowerShell or Command Prompt window and run the following command:
```
Get-WindowsFeature *telnet*
`
``
Look for "Telnet-Server" in the output to confirm that the feature is installed.

11. Enabling Telnet Server:

arduino
- Telnet Server is installed but not yet enabled. To enable it, open PowerShell or Command Prompt as an administrator and run the following command:
```
Install-WindowsFeature -Name Telnet-Server -IncludeManagementTools
```

12. Starting the Telnet Service:

javascript
- Telnet Server is installed and enabled, but the service might not be running. Start the Telnet service with the following command:
```
Start-Service Telnet
`
``

13. Setting Telnet Service to Start Automatically:

javascript
- To ensure that the Telnet service starts automatically with the system, run the following command:
```
Set-Service -Name Telnet -StartupType Automatic
`
``

14. Allowing Telnet Through Windows Firewall:

vbnet
- By default, Telnet traffic might be blocked by the Windows Firewall. To allow it, run the following command:
```
New-NetFirewallRule -Name Telnet-In -DisplayName 'Telnet Server (TCP-In)' -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 23
```

15. Testing Telnet Locally:

javascript
- Test the Telnet server locally by opening a Command Prompt or PowerShell window and running:
```
telnet localhost
`
``
If successful, you should see a command prompt indicating a successful connection.

16. Testing Telnet Remotely:

vbnet
- Test Telnet from another machine by replacing "localhost" with the IP

How to enable telnet on windows server?

If you’re working on a server that doesn’t have telnet installed, you’ll get an error message like this: “Telnet is not recognized as an internal or external command, operable program or batch file”. The good news is that the telnet client is included with Windows and can be enabled using PowerShell or a graphical interface.

If this is your first time installing the telnet client you’ll need to enable it using the legacy control panel in Windows 11 or by using the dism graphical installation method in Windows Server 2022. In the Add Roles and Features Wizard select a role-based or feature-based install and then scroll down and check Telnet Client.

While Microsoft has depreciated the telnet server, it is still possible to use it for testing network connectivity to servers that don’t have a web interface or where strong authentication and encrypted data communications aren’t required. In this post I’ll show you 3 easy ways to quickly install the telnet client in Windows, either by command line or through the graphical user interface.

Step 1: Enable the feature

Telnet is a simple client/server protocol that allows users to remotely access a computer. This can be useful for troubleshooting or when you need to check ports that are open or close. However, it is not secure and does not have any authentication policies or data encryption. This is one of the reasons why many people prefer using SSH instead of telnet.

You can enable the telnet feature on your Windows Server 2022 by either using Command Prompt or through Server Manager graphical interface. The easiest method is to use Command Prompt and run the following command.

This will install the telnet client as a Windows feature. When prompted, choose the Role-based or feature-based installation option and click Next. On the Select destination server screen, make sure that your local server is selected and click Next. On the Select features page, check the ‘Telnet Client’ box and click Next. Once the installation is complete, you can select Finish to close the Add roles and features wizard.

Step 2: Set the port

Telnet is a client/server program that allows you to remotely log in to other computers. It is still widely used today because it can be very useful when troubleshooting connection problems or connecting to a remote server for testing purposes. It also sends everything across the wire in plain text, which makes it less secure than other methods of remote access such as SSH.

Microsoft has depreciated Telnet servers since 2012 R2 and Windows 10, and instead recommends installing a 3rd party SSH server for similar capabilities and results. However, if you do want to install a Telnet server, this article will explain how to set up and start it in Windows Server.

The first step in setting up a Telnet server on Windows Server is to open the correct port. This is the port that will accept incoming connections to the server from external users. To do this, log in to the server and then navigate to Start > Administrative Tools > Windows Firewall with Advanced Security > Inbound Rules.

Step 3: Install the client

Telnet is a simple client/server protocol used to communicate with remote servers. It is useful for troubleshooting connectivity issues on a server and can also be used to test whether ports are open. However, due to the fact that it sends information over the network in plain text, telnet is considered insecure and Microsoft has depreciated its use. Instead, it is recommended that users use SSH as it provides secure encrypted communication.

In order to enable telnet on Windows Server you must first install the client. This can be done through the Command Prompt, PowerShell or through the Server Manager graphical interface.

To install the client through PowerShell, open a PowerShell prompt and type the following command:

Conclusion

In around 850 words, you’ve learned how to enable Telnet on Windows Server 2019. This involves installing the Telnet Server feature, enabling it, starting the Telnet service, configuring it to start automatically, and allowing the necessary traffic through the Windows Firewall. Testing both locally and remotely ensures that the Telnet server is operational. Telnet, being an unencrypted protocol, should be used with caution, and secure alternatives like SSH are recommended for secure remote connections.
