看这个TDI Client的代码为什么会出错？？

......
NTSTATUS
CreateConnection(PHANDLE Handle, PFILE_OBJECT *FileObject)
{
NTSTATUS Status;
    UNICODE_STRING Name;
OBJECT_ATTRIBUTES Attr;
IO_STATUS_BLOCK IoStatus;
CHAR Buffer[sizeof(FILE_FULL_EA_INFORMATION) + TDI_CONNECTION_CONTEXT_LENGTH];
PFILE_FULL_EA_INFORMATION Ea = (PFILE_FULL_EA_INFORMATION)ExAllocatePool(NonPagedPool, sizeof(FILE_FULL_EA_INFORMATION) + TDI_CONNECTION_CONTEXT_LENGTH);;

    RtlInitUnicodeString(&Name, L\"\\\\Device\\\\Tcp\");
    InitializeObjectAttributes(&Attr, &Name, OBJ_CASE_INSENSITIVE, 0, 0);

    Ea->NextEntryOffset = 0;
    Ea->Flags = 0;
    Ea->EaNameLength = TDI_CONNECTION_CONTEXT_LENGTH;
    Ea->EaValueLength = 0;
    RtlCopyMemory(Ea->EaName, TdiConnectionContext, Ea->EaNameLength + 1);

    Status = ZwCreateFile(Handle,  GENERIC_READ | GENERIC_WRITE | SYNCHRONIZE, &Attr, &IoStatus, 0, FILE_ATTRIBUTE_NORMAL,  FILE_SHARE_READ, FILE_OPEN, 0, Ea, sizeof(Buffer));
ExFreePool((PVOID)Ea);
    if (!NT_SUCCESS(Status))
    {
     DbgPrint(\"ZwCreateFile failed!\\n\");
     return Status;
    }

    return ObReferenceObjectByHandle(*Handle, GENERIC_READ | GENERIC_WRITE, 0, KernelMode, (PVOID *)FileObject, 0);
}

ZwCreateFile老是不成功，返回值为0x80000014，但我不知道是哪里错了～～　请各位指点～～

我也遇到同样的问题，不知你解决了没有？
