ndisfregisterFilterDriverがndis_status_failureを返すのはなぜですか？

Question

私はNDIS中間フィルタドライバを書いていますが、私は起こる前に何も起こる前に立ち往生しています。

私のコードはまだフィルタドライバを登録しようとしていません：

NTSTATUS 
DriverEntry(
IN PDRIVER_OBJECT DriverObject,
IN PUNICODE_STRING RegistryPath)
{
NDIS_FILTER_DRIVER_CHARACTERISTICS FChars;
NDIS_STRING ServiceName, UniqueName, FriendlyName;
NDIS_STATUS Status;

UNUSED(RegistryPath);

g_FilterObject = DriverObject;

RtlInitUnicodeString(&ServiceName, MIP_SERVICE_NAME);
RtlInitUnicodeString(&FriendlyName, MIP_FRIENDLY_NAME);
RtlInitUnicodeString(&UniqueName, MIP_UNIQUE_NAME);

NdisZeroMemory(&FChars, sizeof(NDIS_FILTER_DRIVER_CHARACTERISTICS));

FChars.Header.Type = NDIS_OBJECT_TYPE_FILTER_DRIVER_CHARACTERISTICS;
FChars.Header.Size = sizeof(NDIS_FILTER_DRIVER_CHARACTERISTICS);
FChars.Header.Revision = NDIS_FILTER_CHARACTERISTICS_REVISION_1;
FChars.MajorNdisVersion = 6;
FChars.MinorNdisVersion = 0;
FChars.MajorDriverVersion = 1;
FChars.MinorDriverVersion = 0;
FChars.Flags = 0;

FChars.FriendlyName = FriendlyName;
FChars.UniqueName = UniqueName;
FChars.ServiceName = ServiceName;

FChars.AttachHandler = FilterAttach;
FChars.DetachHandler = FilterDetach;
FChars.RestartHandler = FilterRestart;
FChars.PauseHandler = FilterPause;

FChars.SetOptionsHandler = FilterRegisterOptions;
FChars.SetFilterModuleOptionsHandler = FilterSetModuleOptions;

FChars.SendNetBufferListsHandler = FilterSend;
FChars.ReturnNetBufferListsHandler = FilterReturnNetBufferLists;
FChars.SendNetBufferListsCompleteHandler = FilterSendComplete;
FChars.ReceiveNetBufferListsHandler = FilterReceive;
FChars.CancelSendNetBufferListsHandler = FilterCancelSend;

FChars.DevicePnPEventNotifyHandler = FilterDevicePnPEvent;
FChars.NetPnPEventHandler = FilterNetPnPEvent;
FChars.StatusHandler = FilterStatus;

DriverObject->DriverUnload = FilterUnload;

Status = NdisFRegisterFilterDriver(DriverObject,
        (NDIS_HANDLE)g_FilterObject,
        &FChars,
        &g_FilterHandle);
if (Status != NDIS_STATUS_SUCCESS)
{
    MDBG("Failed to register filter driver %x", Status);
    return Status;
}

return NDIS_STATUS_SUCCESS;
}

.

他のすべての関数は空です（一部のトレースコードを除く）。彼らはここで関係ありません。

ndisfregisterFilterDriverは常にndis_status_failureを返します。 Documentation なぜこれが起こる可能性がある理由を説明していません。 （私はDDKからサンプルドライバのリテラルコピーを試してみました。）

I don't see anything wrong with the code you've posted. Is MIP_UNIQUE_NAME defined to be identical to the NetCfgInstanceId from the INF? (Incidentally, remember to generate a new GUID different from the sample GUID — I've seen collisions, and it's not pretty).
