Hi,

I have my virtual disk driver running under windows xp for success but just only for Administrator account. When i try to access disk drive (m:) under other account it is unavaible. Disk device is created with IoCreateDeviceSecure:

RtlInitUnicodeString(&sddl, _T("D:P(A;;GA;;;SY)(A;;GA;;;LS)(A;;GA;;;BA)(A;;GA;;;BU)(A;;GA;;;WD)(A;;GA;;;RC)(A;;GA;;;AU)(A;;GA;;;BG)(A;;GA;;;IU)"));
// here i try to list all and give access to all



    status = IoCreateDeviceSecure(
                 DriverObject,
                 sizeof(DEVICE_EXTENSION),
                 &device_name,
                 DeviceType,
                 FILE_DEVICE_SECURE_OPEN | FILE_REMOVABLE_MEDIA,
                 FALSE,
                 &sddl,
                 NULL,
                 &device_object
             );
