I have no idea what Microsoft was thinking when they stopped installing Telnet as a standard part of the OS. It’s really frustrating for a systems admin to try to test port connectivity to be greeted by:
‘telnet’ is not recognized as an internal command, operable program of batch file.
Need to install it quickly? Copy these two commands and paste them into powershell. Paste them together, the line break will add the CR for you.
Import-Module servermanager
Add-WindowsFeature telnet-client
And viola! Telnet will be there for you!
