IT professionals frequently need connectivity and management tools. The Telnet Client is one of the most basic tools for such activities. Using this tool, you can connect to a remote Telnet server and run applications on it. This is also a very useful tool for testing the connectivity to remote servers, such as those running SMTP services, web services and so on. In this article we will discuss how to install or enable Telnet client for Windows Server 2012, using the GUI interface or command prompt.
Microsoft operating systems since Windows NT have included the Telnet client as a feature. However, later Operating Systems beginning with the Windows Server 2008 and Windows Vista prefer not to enable it by default. Although you can always use a third-party tool for assisting you in remote connections and for troubleshooting connectivity, you can enable the Telnet client on your Windows Server 2012 any time needed.
