Renabling ICMP "Ping" on a Windows 10 PC
For monitoring PCs and automation e.g. turning on lights and Amps when a PC is on can be useful it also provides basic monitoring that the PC is on and Windows is running / on the network. It's not a substitute for testing any services are running but its a good starting point.
Recently the default has changed to Windows 10 no longer responds to Ping requests. This is understandable and a good change.
If you want to enable you can allow ICMP in the firewall manually or issues the following elevated command.
netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow
If you want to learn more about ping, its used for many things and can carry a limited payload. It's not reliable or even available on secure networks but it can be useful in some situations.
