Wake on Lan : Desktop PCs

We have a number of machines on our network, laptops and desktops.

We use a specialist system to to issue Wake On Lan Magic Packets to wake all of the machines together. This appears to work fine with the laptops but the desktops don't wake.

We've tried several different machines, all have the correct BIOS settings and Windows Settings as described by their respective manufacturers. All receive the magic packet if we run a monitor on the machine to test prior to sleeping. When we sent the machines to sleep however they do not Wake up On Lan. They do wake up from sleep if a key is pressed.

I believe I have pretty much tried every permutation of setting I can find - any advice?

Many thanks

David

Have you checked the power management settings for the network cards? Could be one possibility. If the computers are allowed to power them down to conserve power, that might prevent them from properly getting the magic packet...

Yes - we checked through this, we've disabled or turned off anything like this.

A magic packet is generic isn't it, there isn't something where you can sleep on keypress or magic packet.
