安装passthru.sys出现问题，说没有经过mfc数字签名

各位大虾：
 我在安装passthru.sys出现问题，弹出一个对话框，
说sample filter miniport没有经过mfc数字签名。我
选择继续安装,这个框老是出现，那么我怎么才能不让
这个框出现呢？怎么才能正确安装呢？
  我选择不继续是不是也可以正确安装？
  谢谢

然后，我在passthru的driverentry()中使用
#define DEVICE_NAME L"\\DEVICE\\PASSTHRU"
#define DEVICE_SYMBOL L"\\??\\PASSTHRUSYM"
RtlInitUnicodeString((PUNICODE_STRING)DeviceName,(PCWSTR)DEVICE_NAME);
RtlInitUnicodeString((PUNICODE_STRING)SymbolicName,(PCWSTR)DEVICE_SYMBOL);


NdisMRegisterDevice(WrapperHandle,DeviceName,SymbolicName,MajorFunctions,pDeviceObject,NdisDeviceHandle);
注册了。我现在编写了一个win32应用程序，来用createFile()
打开passthru。
HANDLE hDevice;
hDevice=CreateFile("\\\\.\\PASSTHRUSYM",
                         GENERIC_WRITE | GENERIC_READ,
                         0,
                         NULL,
                         OPEN_EXISTING,
                         FILE_FLAG_OVERLAPPED,
                         0
                         );
DWORD error=GetLastError();
可是返回的error=2，应该是没有找到设备。这是为什么呢？
在上一片的问题我选择了不继续安装，但是网络属性中已经有了
sample filter这项服务。那么，我是因为passthru没有安装成功
还是因为createfile（）调用的不对呢？请大侠们多多指点！谢谢

没有签名就没有吧，你要想要的话还得去找那个“帐单之门”(Bill Gates),继续就是了。
你在Passthru中又有没有创建如下例程，这个程序是不受Win32及其它内核驱动的调用的:
DiverObject->MajorFunction[IRP_MJ_CREATE] = PassthruCreate;
...
...
...
想与它通信可不是简单创建一个名字就可以的，你还是先再看看DDK吧！

我选择继续的话，这个对话框老是出现！真是郁闷
我有定义create亚。
DriverObject->DriverStartIo=PassthruStartIo;
MajorFunctions[IRP_MJ_CREATE]=PASSTHRUCREATE;
MajorFunctions[IRP_MJ_READ]=PassthruRead;
NdisMRegisterDevice(WrapperHandle,DeviceName,SymbolicName,MajorFunctions,pDeviceObject,NdisDeviceHandle);
  NTSTATUS PASSTHRUCREATE(PDEVICE_OBJECT fdo,PIRP  Irp)
{
PIO_STACK_LOCATION IrpStack=IoGetCurrentIrpStackLocation(Irp);
return CompleteIrp(Irp,STATUS_SUCCESS,0);
}

NTSTATUS CompleteIrp(PIRP  Irp ,NTSTATUS status , ULONG info)
{
Irp->IoStatus.Status=status;
Irp->IoStatus.Information=info;
IoCompleteRequest(Irp,IO_NO_INCREMENT);
   return status;
}
真的很奇怪。看来可能是没有安装好

看看这部分代码先：

DriverObject->MajorFunction[IRP_MJ_CREATE] = PacketOpen;
    DriverObject->MajorFunction[IRP_MJ_CLOSE]  = PacketClose;
    DriverObject->MajorFunction[IRP_MJ_READ]   = PacketRead;
    DriverObject->MajorFunction[IRP_MJ_WRITE]  = PacketWrite;
    DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL]  = PacketIoControl;

    DriverObject->DriverUnload = PacketUnload;

各位大侠：我在passthru的基础上进行编程，我发现如果我加入
下面两句：//RtlInitUnicodeString(&DeviceName,DEVICE_NAME);
  //RtlInitUnicodeString(&SymbolicName,DEVICE_SYMBOL);
我一旦舔加这个passthru.sys这个服务，系统马上down机，这是为什么呢？我真的是很郁闷，请各位大侠多多指点，我的
部分代码如下：

#define DEVICE_NAME L"\\DEVICE\\PASSTHRU"
#define DEVICE_SYMBOL L"\\DosDevices\\passthruSymbolic"

)

   //RtlInitUnicodeString(&DeviceName,DEVICE_NAME);
  //RtlInitUnicodeString(&SymbolicName,DEVICE_SYMBOL);

  NdisMInitializeWrapper(&WrapperHandle, DriverObject, RegistryPath, NULL);

    
MajorFunctions[IRP_MJ_CREATE]=PASSTHRUCREATE;
MajorFunctions[IRP_MJ_READ]=PassthruRead;

//NdisMRegisterDevice(WrapperHandle,&DeviceName,&SymbolicName,MajorFunctions,pDeviceObject,NdisDeviceHandle);

}

NTSTATUS PASSTHRUCREATE(PDEVICE_OBJECT fdo,PIRP  Irp)
{
PIO_STACK_LOCATION IrpStack=IoGetCurrentIrpStackLocation(Irp);
return  STATUS_SUCCESS;
//return CompleteIrp(Irp,STATUS_SUCCESS,0);
}

NTSTATUS CompleteIrp(PIRP  Irp ,NTSTATUS status , ULONG info)
{
Irp->IoStatus.Status=status;
Irp->IoStatus.Information=info;
IoCompleteRequest(Irp,IO_NO_INCREMENT);
   return status;
}

PDRIVER_DISPATCH MajorFunctions[IRP_MJ_MAXIMUM_FUNCTION+1];


:PDEVICE_OBJECT *pDeviceObject=NULL;
:NDIS_HANDLE *NdisDeviceHandle=NULL;

PDEVICE_OBJECT pDeviceObject=NULL;
NDIS_HANDLE NdisDeviceHandle=NULL;

RtlInitUnicodeString没错

多多交流，我也才学

是呀，我也是正在学习，希望能多多交流。
现在我发现好像是Status=NdisMRegisterDevice(WrapperHandle,NULL,&SymbolicName,MajorFunctions,&pDeviceObject,&NdisDeviceHandle);
这条语句的问题，我现在一把这句话加上，已安装就down机。
对了，pDeviceObject好像应该设成全局变量把,因为
以后象create等都要这个变量作参数

就是Status=NdisMRegisterDevice(WrapperHandle,NULL,&SymbolicName,MajorFunctions,&pDeviceObject,&NdisDeviceHandle);
这条语句的问题，
因为你的定义不对！！！
见前我的定义！
PDRIVER_DISPATCH MajorFunctions[IRP_MJ_MAXIMUM_FUNCTION+1];


ERROR:PDEVICE_OBJECT *pDeviceObject=NULL;
ERROR:NDIS_HANDLE *NdisDeviceHandle=NULL;

PDEVICE_OBJECT pDeviceObject=NULL;
NDIS_HANDLE NdisDeviceHandle=NULL;

我现在按照你的代码加上去，可是还是不行亚。
请问你有没有测试过的代码，发给我看一看，
非常感谢，我的e_mail是：baijbupt@263.net

我现在也是遇见这个问题，现在可以判断的是
ndismregisterdevice和NdisIMRegisterLayeredMiniport
之间的问题，如果在程序中现运行ndismregisterdevice,那么
可以成功，但是，当运行到NdisIMRegisterLayeredMiniport
时就失败了。如果程序中把NdisIMRegisterLayeredMiniport放在
ndismregisterdevice，那么NdisIMRegisterLayeredMiniport
可以成功，但是ndismregisterdevice失败

非常谢谢qsc的指点。我将尽快给你专家分（因为
我现在还不会给！：））
上篇的代码基本是正确的，只要改动：
if(NT_SUCCESS(Status))
{
DBGPRINT("NdisMRegisterDevice fail!\n");
// NdisMDeregisterDevice(NdisDeviceHandle);

// return Status;
}
else
{
DBGPRINT("NdisMRegisterDevice Success!\n");
deviceObject->Flags |= DO_BUFFERED_IO;
pDeviceObject = deviceObject;
NdisDeviceHandle=ndisDeviceHandle;
}
把if 和lelse的内容对调一下就可以了。另外，提醒一下，
这个源代码有create的处理但是没有closehandle的处理。
要正常使用要加上close的dispatch irp

你将系统的配子改一下就好了，我是这样做的
