无法打开计算机上的服务控制管理器

我正在尝试编写一个程序,该程序将连接到远程服务器并显示服务的某些状态。该服务也是由我们(我的公司)编写的。
为了做到这一点,我写了一个控制台应用程序,代码是
static void Main(string[] args)
{
ConnectionOptions options = new ConnectionOptions();
options.Password = "mypassword";
options.Username = "Administrator";
options.Impersonation =
System.Management.ImpersonationLevel.Impersonate;
ManagementScope scope =
new ManagementScope(
"''''ip_of_the_server''root''cimv2", options);
scope.Connect();
ServiceController svc = new ServiceController("My_Service_Name", "ip_of_the_server");
var status = svc.Status.ToString();
Console.WriteLine(svc.DisplayName + " : " status);
}
但我做不到。我得到的错误是:
Cannot open Service Control Manager on computer 'ip_of_the_server'. This operation might require other privileges.
内部异常:"访问被拒绝"。

知道怎么解决吗??
由于您已经设置了管理范围,只需使用WQL查询WMI提供程序以获得正确的WMI对象,在本例中为WIN32_Service,类似于以下内容:
var svc = new ManagementObjectSearcher(
scope,
new ObjectQuery("Select Status,State from Win32_Service where Name='My_Service_Name'"))
.Get()
.GetEnumerator();
if (svc.MoveNext())
{
var status = svc.Current["Status"].ToString();
var state = svc.Current["State"].ToString();
Console.WriteLine("service status {0}", status);
// if not running, StartService
if (!String.Equals(state, "running",StringComparison.InvariantCultureIgnoreCase) {
( (ManagementObject) svc.Current ).InvokeMethod("StartService", new object[] {});
}
}
else
{
Console.WriteLine("service not found");
}
ManagementObjectSearcher负责检索WMI管理对象的集合。ObjectQuery将从作用域返回类的实例。我们可以执行基本的sql select语句来选择和投影结果集。
迭代器返回ManagementObjectBase,该ManagementObjectBase具有Item
访问器,用于从返回的实例中检索属性。
