One problem encountered when playing today, would like to ping the campus LAN ip others to play, but not ping his computer.

C:\Users\Administrator>ping 10.3.78.70

正在 Ping 10.3.78.70 具有 32 字节的数据:
请求超时。

请求超时。

10.3.78.70 的 Ping 统计信息:
    数据包: 已发送 = 4，已接收 = 0，丢失 = 4 (100% 丢失)，

the reason:

Because the windows firewall by default are not allowing people to ping, so the method is to modify the firewall settings

Step: Control Panel → System and Security → Windows Firewall → Advanced → Inbound Rules → File and Printer Sharing (Echo Request - ICMPv4-In) is set to enable

Then, to be able to successfully ping through. everything is ok
