I want to develop a software that need to know the notification when a
windows PC in the LAN is powering on, I don't want this software to do
polling, I want this software can get the notification from the powering on
PC.

Assume the PC does not have any software except the Windows system, even
there is no snmp installed. Is it possible to do this? How about get the ARP
packet? If it is possible, how to do it in Windows?


Thank you very much!
 
write a packet sniffer looking for dhcp requests may do it. (assuming the
clients use dhcp).
 
So you need to write service which announce ( send broadcast ) to LAN
computers
( or to your single server ) about it's wake-up.

so, to sum up:

either have a service on the clients notify the server at startup, or have a
packet sniffer sniffing for traffic (dhcp, or arp, or anything
