Installing the Telnet Client in Windows Server

Although every communication is (rightfully) moving to TLS, the cleartext tool "telnet" is still quite handy on a Windows based server to check if a port is open and/or basic network connectivity is working. Unfortunately, the telnet client (NOT the server) is no longer part of a Windows default install.
To install the telnet client (NEVER install the server), you could either click through the GUI (Server Manager -> Add roles and features -> ..) or you could use the fast way via the command line:
Enabling the telnet client through command prompt
dism /online /Enable-Feature /FeatureName:TelnetClient
Enabling the telnet client through PowerShell
Install-WindowsFeature -name Telnet-Client
And now a simple
telnet localhost 80just works :D.
