If you want to check a port on a remote machine from windows, you can use telnet but it's not installed by default. Instead you can use Test-NetConnection powershell command or tnc directly available from a windows terminal or powershell terminal, I'll show few examples how to use it.
- Usage :
Get-Help tnc
- Check port 443 (https) on google.Com :
tnc google.com -Port 443
- Check well known service port (SMB here) on localhost :
tnc localhost -CommonTcpPort SMB
