I'm in a position where I need to enable Wake on LAN for roughly 50 machines. I don't want to have to go round every one and adjust the settings for it, but it's looking increasingly like I'll have to.

The network cards have a setting in the "advanced" tab of the adapter configuration panel that needs to be toggled from "off" to on to allow the wake on LAN to take place (I can't provide a screenshot from one of the machines with that card, but here's one of the same dialog from a virtual machine so you know which one I mean).

Note that this setting isn't the same as the one on the power management tab.

I'd ideally like to change this configuration from a command line utility or script; could anyone point me to a location in the registry where device configuration is held, or a utility which could change these settings from Command Prompt?

Thus far, I've found DevCon - a command line alternative/frontend to device manager, but I don't think it has the settings I need.

Cheers in advance :)

It appears this can be set using WMI. Look at the Win32_NetworkAdapterConfiguration class for the details. Also, you can use Powershell to manipulate WMI from the command-line.

Solved this by searching in the registry for the brand name and modifying a boolean key in the HKEY_Local_Machine\system branch for the network card.
