我正在尝试使用WMI和C＃从远程计算机的事件查看器获取通知。我能够连接系统，也可以使用来获取事件日志ManagementObjectSearcher。但是，当我尝试使用ManagementEventWatcher.Start方法时，出现了一个异常：
访问被拒绝。（来自HRESULT的异常：0x80070005（E_ACCESSDENIED））
我已经在WMI控制中root\cimv2赋予了权限，并且还赋予了DCOM Config中用户帐户的管理员权限。
我有普通的Windows应用程序，因此我不使用ASP.net（ASPNET用户）。
我的代码是：
ConnectionOptions connectionOptions = new ConnectionOptions();
connectionOptions.Username = @"Domain\UName";//txtUserName.Text;
connectionOptions.Password = "pass";//txtPassword.Text;
connectionOptions.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope managementScope = new ManagementScope(@"\\server\root\cimv2",connectionOptions);
managementScope.Options.EnablePrivileges = true;
managementScope.Connect(); // this line is executing fine.
eventWatcher = new ManagementEventWatcher(managementScope, new EventQuery("Select * From __InstanceCreationEvent WHERE TargetInstance ISA 'Win32_NTLogEvent' and TargetInstance.LogFile = 'Application'"));
eventWatcher.EventArrived += new EventArrivedEventHandler(Arrived);
eventWatcher.Scope.Options.EnablePrivileges = true;
eventWatcher.Start(); // Error occurs here
