Testing Ports on a Remote Machine with PowerShell
14 March 2017

If you do not wish to enable TelNet just to test ports on a remote machine then PowerShell has a solution. PowerShell comes with Test-NetConnection, which gives detailed information about a connection.

Example of using Test-NetConnection

Test-NetConnection www.geoffhayward.eu -Port 443 -InformationLevel "Detailed" 

I hope this helps.
