WinDbg无法加载Symbols的问题

大家好！
    我在使用Windbg查看dump信息时，出现无法加载symbols问题，请问如何解决？以下为WinDbg输出信息：

解决了，和大家共享一下。

需要在Symbols file path中添加
SRV*d:\symcache*http://msdl.microsoft.com/download/symbols;E:\TestDriver\NDISDriver\drivers_ndis6.0\build\target\Win32\x86\checked

 后者对应于驱动程序的PDB文件所在目录。因为没有搜索该目录，所以无法加载驱动对应的符号。《Windows驱动开发技术详解》中没有说清楚。
