事情是这样的，楼主想用!locks分析死锁问题，但是输入后就显示
0:004>!locks
NTSDEXTS:Unabletoresolventdll!RtlCriticalSectionList
NTSDEXTS:Pleasecheckyoursymbols
然后查找了各种博客，说要输入SRV*D:\mysymbol*http://msdl.microsoft.com/download/symbols
下载符号表，但是加载就会报错：

Youcantroubleshootmostsymbolrelatedissuesbyturningonsymbolloadingdiagnostics(!symnoisy)andrepeatingthecommandthatcausedsymbolstobeloaded.
Youshouldalsoverifythatyoursymbolsearchpath(.sympath)iscorrect.

然后就没有然后了。。。求解这到底该咋办呢？

执行一下!sym noisy
然后再执行一下.reload看看错误信息

那个*和http之间不要有空格
