How to Enable Telnet In Windows 10 and Server 2012 R2?

Controlling Windows Servers remotely is a daily activity of a network and system administrators, whether with command line or remote desktop. Here I’m using Telnet command Line tool. Telnet is a protocol that enables you to connect remotely to computers. By default the telnet services is not enabled on Windows Server and Clients. I’m going to show you how to enable telnet in Windows 10 and Windows Server 2012 R2 or vNext Server. So you need to know the telnet port also. The default port of telnet is 23 and when you enable telnet on Windows, you make sure that the port 23 is not blocked by Windows Firewall or Anti Virus

Telnet is not a good chose to control a system over the internet. Because it is not secure and the communication is occurred on a non encrypted mode. If you want to secure Telnet communications, you must do it with Internet security protocol (IPSec). Securing telnet is out of scope of this topic, we simply enable telnet in Windows 10 client and Windows Servers. It work the same on Windows Server 2008, Windows 7, 8 and Windows 8.1.

Enable Telnet In Windows 10 Client Side

Firstly, we must enable telnet in Windows 10 and next on Windows Server. To work perfectly, telnet client must installed on client side and telnet Server must be installed on Server side. In order to enable telnet, go to control panel -> Programs and Features -> and click Turn Windows Features on or off.

For an expert it is a very long way, so just type “optionalfeatures” on the Run and press enter to open Windows Features page.

On the Server Role page, do nothing and just click Next. So we want to install features not Roles. And I don’t take Screenshot, it is going to make heavy my article.
