 Run PowerShell as Administrator on the target PC. 
 
 Allow ping from local subnet : 
 New-NetFirewallRule -DisplayName "Allow ICMP Ping LAN" -Direction Inbound -Protocol ICMPv4 -IcmpType 8 -RemoteAddress LocalSubnet -Action Allow 
 
 Replace LocalSubnet with your range if needed (e.g., 192.168.1.0/24 ). 
 Test: ping target PC from another LAN PC.
