当对类Win32_DiskDrive使用非管理员用户时，WMI给出了通用故障

Question

我为非管理员帐户提供了appropriate permission，并且该用户已添加到“分布式COM用户”组中。

尝试访问Win32_DiskDrive或Win32_DiskDriveToDiskPartition类时，出现Generic Failure错误。是否需要任何额外的许可？

• 如果我使用的是管理员帐户，那同样有效。

• 其他类，例如Win32_NetworkAdapterConfiguration使用非管理员帐户给出结果

     if (!String.IsNullOrWhiteSpace(username) && !String.IsNullOrWhiteSpace(password))
              {
                  ConnectionOptions connectionOptions = new ConnectionOptions
                  {
                      Impersonation = ImpersonationLevel.Impersonate,
                      Authentication = AuthenticationLevel.PacketPrivacy,
                      Timeout = TimeSpan.FromSeconds(60),
                      Username = username,
                      Password = password
                  };
  
                  var managementScope = new ManagementScope(@"\\" + assetNameOrIpAddress + @"\root\cimv2", connectionOptions);
                  managementScope.Connect();
                  managementObjectSearcher.Scope = managementScope;
              }

您应该添加正确的权限

       ConnectionOptions connOptions = new ConnectionOptions();
       connOptions.Impersonation = ImpersonationLevel.Impersonate;
       //Add AuthenticationLevel that suits your need
       connOptions.Authentication = AuthenticationLevel.PacketPrivacy; 
       connOptions.EnablePrivileges = true;

       ManagementScope scope =
  new ManagementScope("MANAGEMNET_PATH"
, connOptions);
       scope.Connect();


       ObjectQuery query = new ObjectQuery(
           "YOUR QUERY");
       ManagementObjectSearcher searcher =
           new ManagementObjectSearcher(scope, query);
