Проблема следующая: При попытке получать асинхронно события с удаленного компьютера в сети происходит ошибка 0x80070005 (E_ACCESSDENIED), т.е. отказано в доступе. Хотя если просто пытаюсь получить единоразово событие, к примеру запуск notepad.exe на удаленном компьютере то все нормально. Пример кода получения события запуска процесса: | Код |
using System;
using System.Management;
// This example shows synchronous consumption of events.
// The client is blocked while waiting for events.
public class EventWatcherPolling
{
public static int Main(string[] args)
{
ConnectionOptions options =
new ConnectionOptions();
options.Username = "test";
options.Password = "test123";
ManagementScope scope =
new ManagementScope(
"\\\\192.168.0.102\\root\\cimv2", options);
scope.Connect();
// Create event query to be notified within 1 second of
// a new process being created
WqlEventQuery query =
new WqlEventQuery("__InstanceCreationEvent",
new TimeSpan(0, 0, 1),
"TargetInstance isa \"Win32_Process\"");
// Initialize an event watcher and subscribe to events
// that match this query
ManagementEventWatcher watcher =
new ManagementEventWatcher(scope,query);
// times out watcher.WaitForNextEvent in 5 seconds
//watcher.Options.Timeout = new TimeSpan(0, 0, 5);
// Block until the next event occurs
// Note: this can be done in a loop if waiting for
// more than one occurrence
Console.WriteLine(
"Open an application (notepad.exe) to trigger an event.");
ManagementBaseObject e = watcher.WaitForNextEvent();
//Display information from the event
Console.WriteLine(
"Process {0} has been created, path is: {1}",
((ManagementBaseObject)e
["TargetInstance"])["Name"],
((ManagementBaseObject)e
["TargetInstance"])["Caption"]);
Console.ReadLine();
//Cancel the subscription
watcher.Stop();
return 0;
}
}

Тут все нормально, запускаю на компьютере с ip=192.168.0.102 notepad.exe и получаю об этом событии в консоли уведомление. А если пытаюсь получать асинхронно: | Код |
using System;
using System.Management;
//using System.Windows.Forms;
namespace WMISample
{
public class WMIReceiveEvent
{
public WMIReceiveEvent()
{
try
{
ConnectionOptions options =
new ConnectionOptions();
options.Username = "test";
options.Password = "test123";
ManagementScope scope =
new ManagementScope(
"\\\\192.168.0.102\\root\\cimv2", options);
scope.Connect();
// Create event query to be notified within 1 second of
// a new process being created
// WqlEventQuery query =
// new WqlEventQuery("__InstanceCreationEvent",
//"TargetInstance isa \"Win32_Process\"");
WqlEventQuery query = new WqlEventQuery(
"SELECT * FROM __InstanceCreationEvent WITHIN 10");
// WqlEventQuery query = new WqlEventQuery(
// "SELECT * FROM __InstanceCreationEvent WITHIN 10");
ManagementEventWatcher watcher = new ManagementEventWatcher(scope,query);
Console.WriteLine("Waiting for an event...");
watcher.EventArrived +=
new EventArrivedEventHandler(
HandleEvent);
// Start listening for events
watcher.Start();
// Do something while waiting for events
System.Threading.Thread.Sleep(10000);
// Stop listening for events
watcher.Stop();
return;
}
catch (ManagementException err)
{
Console.Write("An error occurred while trying to receive an event: " + err.Message);
}
}
private void HandleEvent(object sender,
EventArrivedEventArgs e)
{
Console.WriteLine("__InstanceCreationEvent event occurred.");
}
public static void Main()
{
WMIReceiveEvent receiveEvent = new WMIReceiveEvent();
return;
}
}

то на этапе: Вылетает ошибка: | Код |
UnauthorizedAccessExeption не обработано.
Отказано в доступе. (Исключение из HRESULT: 0x80070005 (E_ACCESSDENIED))

Непойму почему... может кто-нибудь подсказать? |
