Problem

I tried to telnet on my windows server 2008 R2 but got the below error.

C:\Windows\system32>telnet
'telnet' is not recognized as an internal or external command,
operable program or batch file.

Solution

I got the above error because the telnet client was not installed on my server. Here I have shown the process of how to enable telnet in windows server 2008 R2. Telnet is a windows feature which can be turned on or off, by default it is turned off.

Enable Telnet in Windows Server 2008 R2

• Open Server Manager by clicking on Start > Server Manager or right-click on the My Computer and then click on Manage. You may also open this window by clicking on Contol Panel > Programs and Features > Turn Windows Features on or off It will open the Server Manager window.
• Click on Features available in the left panel of the server manager and then click on Add Features link available on the right side.
• It will open a new window Select Features, scroll down and select the Telnet Client and click on the Next button.
• Click on the Install button.
• It will take a few moments to complete the installation, once the installation is completed you get the message that Installation Succeeded.

Now you may verify that the telnet client has been successfully installed.
