How to install telnet on Windows 7

Telnet has been around since, well longer than any EnGraph employees have been alive. However, it is still very handy to determine if a client computer can talk to specific server on a specific port. We use it mostly to determine if there is a network rule blocking our access to SQL server. The syntax is simple - "telnet someIP 1433"

Sadly, it is not installed by default on Windows 7 and adding it via Control Panel takes way too many clicks. 

Thankfully, there is the Package Manager and hat tip to TechNet for the one-line installation of Telnet.

Click Start + R on the keyboard (or Start button, type run), then type the following into the prompt and press enter to install Telnet:

cmd /k pkgmgr /iu:"TelnetClient"
