这两天利用WinDbg和 vmware 调试驱动，再调试时，要加载符号表，我的符号表再D盘，symbols path 、source path和image path 分别为如下：
  E:\DriverProject\DriverProc\checked\;Srv*D:\symbols*http://msdl.microsoft.com/download/symbols/

E:\DriverProject\DriverProc\checked\

E:\DriverProject\DriverProc\DriverProc\

在启动虚拟机（虚拟机的串口什么的配置保证没有问题）和windbg后，不能下断点，而且在下断点之前出现这种提示：

这些是什么概念，模块加载完全但符号表没有为这些驱动加载？怎么处理这个问题？（我的网络是正常的，而且windbg也下载了些符号表，共19.8兆。）高手快来，help me....Thank you....
