Disable network card

NTDEV
1

Dear all：
I wrote an UpperFilter driver of USB and disables the USB devices by
marking the IRP_MJ_READ， IRP_MJ_WRITE， IRP_MJ_DEVICE_CONTROL，
IRP_MJ_INTERNAL_DEVICE_CONTROL requests failed。
status = STATUS_ACCESS_DENIED;
Irp->IoStatus.Status = status;
Irp->IoStatus.Information = 0;
IoCompleteRequest(Irp, IO_NO_INCREMENT);
return status;
Now I want to disable the network cards too，I simply set it as the
UpperFilter of NET。 It can work under windows xp，but under win7 it can not
work。
I'm not familiar with drivers。Is there any way to disable the network
cards?
Any suggestions would be greatly appreciate;

Best Regards
