When the site is configured for Wake On LAN and clients are configured for wake-up proxy, the process works as follows: What makes it exciting is that SCCM can now find another client on the same subnet and wake up its neighbour. This requires the PC network interface and BIOS to support WOL. Wake-on-LAN (WoL) is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened by a network message.. This worked fine for computers sat on the same subnet and VLAN as the server, but getting this to work when the client device is in a different subnet took a bit of work.

Another useful feature of the tool is its monitoring engine which checks the status of remote computers after a magic packet has been sent and reports whether the operation was executed successfully or not. It works by reading a .csv file that has the hostnames and MAC’s in two columns, then it creates the WOL packets for each computer and broadcasts them out on the network. A couple of years ago I wrote about the pain of getting Wake on LAN to work on HP switches.While this got some of my machines to work, there was still quite a large proportion (about 60%) that weren’t playing ball. wakes all Desktop computers.

Last weekend, I finally got around to it, and accomplished it by using only Wake On LAN (WOL) and PowerShell (with PowerShell Web Access, WinRM and CredSSP). These packets contain the MAC address of the PC they are destined to wake – since they should be received by all devices the receiving device can filter out any requests for other PCs. Wake-up proxy uses a peer-to-peer protocol and elected computers to check whether other computers on the subnet are awake, and to wake them if necessary.
