Turn off Windows 7 NIC Sleep mode

Does anyone know if there is a group policy in windows 7 (or at the domain level) that i can use to turn off sleep mode on the network card? this has been a problem for us and i need to be able to disable it. i know this can be done in the registry if you know the hardware ID or GUID the only problem is that i have a universal image so every machine might have a different ID because they have a different model of network card.

It doesnt look like this is possible through group policy....yet???

See below from a MSFT moderator, the workaround appears to be the scripting you mentioned or possibly through WMI.

HI
the windows 7 NIC sleep is used only on laptops.
if you are using laptops then look for an application which is managing that on the laptop if you do it once then you can image it and you are good.

on regular computers you need to change the power settings from control panel.

To add to what artoaperjan stated above, for example, Dell and Lenovo have OEM software installed to perform these types of tasks.

Although this was not the answer it did help me to get there. what i ended up doing was this (from the link that you provided)

NOTE: the information below was not quite correct, i needed to add the PnPCapibilities dword with a value of 118 (or 280) to the device number 0007 (seemed to be the same on all of my machines). i did this with a custom command line in my deployment task sequence in MDT 2010. worked like a charm after that!
