Powershell 获取本地计算机上虚拟机的虚拟机间歇性故障

我们最近开始在一些操纵VM的powershell脚本上出现间歇性故障。我能够将问题归结为以下几点：

$ErrorActionPreference = "Stop"
for ($i=0;$i -lt 100000; $i=$i+1) {get-vm * | write-host}

此命令将运行并打印本地Hyper-V虚拟机（目前有4个）一段时间（数百或数千次），但最终将失败：

PS>TerminatingError(Get-VM): "The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: The computer 'LOCALNAME' could not be resolved. Make sure you typed the machine name correctly and that you have network access."

然后，我可以查看当前的$Error变量，以获得有关异常堆栈的更多信息，我已经在下面粘贴了异常堆栈。本地计算机的名称是

LOCALNAME

。关于什么可能导致这种间歇性故障或如何诊断它，有什么想法吗？到目前为止，我已经在没有任何运气的情况下查看了事件日志，我很快就可以重新想象这台机器了

我们也遇到过类似的问题——将范围缩小到DNS随机丢弃。我写了一个nslookup检查，循环了数十万次，并记录了它的成功/失败。我们能够准确地指出，每小时一到两次，DNS将停止解析任何内容仅一两秒钟，然后恢复。仍然不确定DNS错误的根本原因，但这是导致我们的应用程序错误的原因。只是一个想法！谢谢你的想法，尼克。我认为这实际上也是我们正在发生的事情。我们的dns服务器在出现至少一些问题的时候出现了故障。有点奇怪，这是本地机器的感觉。。。如果它再次发生，我可能会看到将-ComputerName指定为127.0.0.1是否有助于避免尝试查找名称
