Wake-On-LAN not working in W2K?

I am facing a problem in using the winsocket. I have to "wake-up"
the system in the network using MAC address. I am using Wake-On-LAN
technology. My network card supports this (3COM Fast Ethernet
3C905C-TX) feature. I am using UDP protocol. I am calling the
"sendto" function with appropriate MAC address. It wakes up the
windows 98 system, but it fails in windows 2K server system. Waiting
for the reply. Thanks
