无法使用System.Management获取安装的vm机器的软件详细信息

Question

我的要求是获取安装的vm机器的软件详细信息并将详细信息存储在db中。但是当我尝试使用System.Management类获取详细信息时，我收到以下错误

System.Runtime.InteropServices.COMException：'RPC服务器不可用。 （HRESULT异常：0x800706BA）'

下面是我用来获取软件详细信息的示例代码

 string SoftwareQuery = "SELECT * FROM Win32_Product";
        ConnectionOptions connection = new ConnectionOptions();



            connection.Username = "bla bla";
            connection.Password = "Password";

        connection.EnablePrivileges = true;
        connection.Impersonation = ImpersonationLevel.Impersonate;

        ManagementScope managementScope = new ManagementScope(@"\\xxxx.xxxx.cloudapp.azure.com:3389\root\CIMV2", connection);
        managementScope.Path = ManagementPath.DefaultPath;
        managementScope.Connect();


        ObjectQuery queryObj = new ObjectQuery(SoftwareQuery);
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(managementScope, queryObj);

        foreach (ManagementBaseObject managementObj in searcher.Get())
        {

           //get the software list here 

        }

注意：上面的代码正在适当地在Intranet上工作

请让我知道有人有解决方案。

它可能与Windows Management Instrumentation服务处于停止状态有关。看看Starting and Stopping the WMI Service。
