Enable Telnet Client in Windows 8 and Server 2012

The Telnet client is one of the most basic connectivity and management tools that any IT professional needs, and this article will show you how to enable Telnet client in Windows Server 2012 and Windows 8. The Telnet client not only lets you connect to a remote Telnet server and run applications on that server, but is also useful for testing connections to remote servers, such as ones running web services, SMTP services and others.

Using the Telnet client is simple enough and the use of Telnet clients has been covered in several different articles on the Petri IT Knowledgebase. The idea is that once the user has logged on, they can use a command prompt interface that can be used as if it had been opened locally on the Telnet server’s console, and any command the user types is sent to the Telnet Server and executed there. The output from that command is sent back to the Telnet client.

Telnet Client Options

Note: There are many Telnet client tools, where many of them are freely available on the Internet. There are even smartphone and tablet versions that you can download from Google Play or the Apple Store, depending on the OS version on your mobile device. For example, PuTTY is one of the most used apps, as it can perform many types of remote connections, including to Telnet servers. To get the best out of using PuTTY or any other app, understanding how to configure Telnet Windows Server 2012 is essential.
