Explanation

Windows Firewall, when enabled with default settings, blocks inbound ICMP Echo Request packets (used by the ping command). This means a computer can have full network connectivity and Internet access while still being unpingable from other machines. The fix is to create a firewall rule to allow ICMPv4 echo requests. Since the computer already has internet connectivity, permissions, security policy, and Wake-on-LAN are not the cause - the machine is already on and communicating on the network.
