我编写了一个PowerShell脚本块，用于在Azure虚拟机规模集上创建IIS应用程序池和网站。设置多个实例，而该脚本块并行运行时，出现错误对象标识符不代表有效的对象。 （来自HRESULT的异常：0x800710D8），有人可以帮忙吗？

重置IIS并没有帮助，我还确保创建了应用程序池，并等待5秒以完成该过程，仍然是相同的问题。

这是我在脚本块中写的

导入模块-名称WebAdministration

$thumbprint = Get-ChildItem -Path Cert:\LocalMachine\My | where-Object { $_.subject -like $certName } | Select-Object -ExpandProperty Thumbprint
