NdisRegisterDeviceEx() cant open device in WinObj.exe

With an SDDL of SDDL_DEVOBJ_SYS_ALL_ADM_RWX_WORLD_RWX_RES_RWX
(defined in wdmsec.h) NdisRegisterDeviceEx() suceeds and creates the
device with the symbolic link.

Attempting to look at the security if the device in WinObj.exe
(sysinternals) I get the error: 'Unable to open \device\GTNDIS0'

On the same laptop the Ndis 5.1 driver using NdisMRegisterDevice()
creates a device that can be opened by WinObj.exe and other
applications.

Any ideas anyone?
