Verify Connectivity to a Remote Computer
Telnet from a Windows Machine
When providing accessible public services a requirement may arise to test the connectivity externally. This can be done using the built in command line Telnet subject to the Telnet Windows feature is installed. This is unlikely as in most scenarios, Telnet is only installed if required. Additionally, using Putty you can achieve the same result, however try downloading Putty through some Proxy’s and you wont have much luck. But using the built in Windows 10 PowerShell command Test-NetConnection, this is easily achiveable. If you need to test SMTP, HTTP, HTTPS, running the below command can provide you with either “True” or “False”.
