windows – ntdll模块在windbg中无法正确加载,但为什么？

我可以清楚地看到ntdll是一个加载的模块：

当我尝试使用我的堆扩展时,我得到：

.symopt- 100也没有帮助

如果我尝试使用临界区扩展,我会收到类似的错误：

Bad symbols for NTDLL (error 3). Aborting.

我已经读过如果你在32位和64位之间不匹配,或者如果你没有在第一位正确设置符号但我已经使用.symfix并且可以强制我的符号重新加载.reload / f,我在x86进程或32位转储上使用x86调试器,所以我看不出这些问题是如何发挥作用的.

我已经完全开始了新的和卸载的windbg,并从MSDN重新安装了Windows的调试工具,但仍然遇到了同样的问题.当然我错过了一些明显的东西？
