Unknown Unknowns: Windows Server 2012 Power Saving

(A quick post today, but a vital one. This didn’t happen to me but I can imagine it has caught many people out)

So, you’ve got your brand new Windows Server 2012 configured, you’ve got all your power saving methods switched off through the UI, and all the BIOS power saving features are turned off, powering your new box to the best it can get. There’s only one problem; you keep on losing network connectivity! Why is this? We were recently working on a new cluster, and after doing the customary checks to ensure all saving features were switched off I spoke to one of the sys admins to verify that everything had been done. And he showed me one power saving feature on the network cards that is switched on by default, irrespective of all the other power saving features being disabled. Here’s a gallery to show you where it is.
