WFP vs NDIS 深度对比分析它们在网络协议栈的不同层次工作，各有优势。阅读详情

我们在一台win7机子上那装了nmware（win7），也就是说主机和GUEST OS均为WIN7，均为32位。编译完filter后生成两文件一个是ndislwf.sys和netlwf.inf文件。我们在GUEST OS上通过DriverMonitor加载ndislwf.sys后。在主机上打开WINDBG开始调试，断点能进入DriverEntry，但是走到99行NdisFRegisterFilterDriver函数时返回的值为0xc0000001,该值在msdn上和filter代码里均无定义，只知道是失败但是什么原因不知道。哪位高手是否知道是哪的问题吗？谢谢

Routine Description:



    First entry point to be called, when this driver is loaded.

    Register with NDIS as a filter driver and create a device

    for communication with user-mode.



Arguments:



    DriverObject - pointer to the system's driver object structure

                   for this driver



    RegistryPath - system's registry path for this driver



Return Value:



    STATUS_SUCCESS if all initialization is successful, STATUS_XXX

    error code if not.
