windbg 无法对驱动设置断点！windows symbol 加载不完全？？？

本人第一次用windbg,看《天书夜读》时在调试wdk的附带例子 diskperf 时遇到很大麻烦(弄了3天了)。我用的系统host机和guest机都是xp+sp2，VM,windbg用的都是最新的,VM按书上说的配置好，在windbg中Symbol File Path 里内容是SRV*C:\WINDOWS\Symbols*http://msdl.microsoft.com/download/symbols;F:\diskperf\objchk_wxp_x86\i386  ， Source File Path里内容是F:\diskper f  ，Image File Path: F:\diskperf\objchk_wxp_x86\i386 ，其中F:\diskperf 存放了驱动代码(已编译)，网络顺畅，调试时成功连接，调试信息如下:

貌似是缺少symbol文件，但这个东西我网上找不到，现在耽搁在这不知道怎么办，对驱动设计很肤浅,还请大家帮我看看,谢谢！

别人教我这样处理的：建立一个系统环境变量_NT_SYMBOL_PATH值为srv*C:\WINDOWS\Symbols*http://msdl.microsoft.com/download/symbols

我这样也试过的 还是一样的。。 不过谢谢你的答复

.reload

我也是，刚学windebug，错误提示和你一样。这个问题都搞了几天了。不知道楼主解决了没有？

哎呀 我也是这个问题郁闷死了
