我第一次运行this example C++ code from MSDN从远程计算机获取WMI数据时，它工作正常 . 它也适用于与我相同配置的同事： Windows Server 2008 R2 Virtual Machine （域控制器）作为远程机器; Windows 7 host machine （在不同的域中）作为进行呼叫的客户端 .
但是，在某些时候，代码停止工作 . 代码的简要概述：它提示输入凭据，然后连接到远程服务器，然后使用WQL行查询其OS信息 Select * from win32_operatingsystem ，然后检索返回的OS对象，然后请求表示操作系统名称和对象的对象表示机器上的空闲内存，将此信息打印到控制台 . 它在第一次 IEnumWbemClassObject::Next 调用时出现错误，该调用应检索OS对象 .
我目前使用的代码是上面链接的示例代码的略微改编版本 . 这里是.cpp的全部内容（删除了一些注释掉的代码块）：

Press any key to continue . . .
对代码的唯一重大改变是最后的循环 . 如果 EnumWbemClassObject::Next 将 puReturned 参数设置为0（请求的1的indicating 0 objects returned），则MSDN示例不会检查错误，而是会中断循环 . 相反，我显示结果但不对其进行操作，如果 uResult 为0则再次尝试循环，并且只有在没有't. This is obviously a hacky solution that could result in an infinite loop if the code worked properly. It'时才会跳出循环也值得注意的是，当我在尝试循环时，我得到了一个奇怪的访问违规：程序在某一行抛出异常，但当我改变下一行时，问题就消失了 . 这让我觉得内存损坏可能会有些奇怪 .
这是更奇怪的部分：当我运行 WBEMtest.exe （Windows提供的用于运行本地或远程WMI命令的GUI）时， my query also only works on the second try . 像我的代码一样，它在第一次尝试时返回 Error 0x800706bf: The remote procedure call failed and did not execute .
出于好奇，我使用事件记录记录了WMI活动 . 我无法从结果中收集到太多信息（除了我的代码和WBEMtest.exe之间发生了不同的事情），但无论如何它们都在这里：

所以，是的，我正在继续？我已经看到其他人在类似情况下的机器之间看到WMI行为不一致的报告（例如，这里称为Win32_BaseBoard的WMI查询的问题没有返回结果 - 可能't link because of the two-hyperlink max for new users), but I'从未见过令人满意的解释 . 顺便说一下，我开始使用新VM和仍然有这个问题（虽然每隔一段时间WBEMtest.exe没有在第一次尝试时出错） .
