WMI-事件​​注册失败(访问被拒绝) [英] WMI - Event registration failed (Access denied)

问题描述

 

 当我尝试从Windows 7计算机远程在Windows 2008 Hypervisor上注册事件时，出现访问被拒绝"错误.

 I am getting Access Denied error when i try to register events on Windows 2008 Hypervisor remotely from a Windows 7 machine. 

在这里，我正在注册用于启动VM的事件.

Here i am registering events for poweron of VMs.

当我的两台计算机都在域中时，此代码可以正常工作.我将它们(Win 2008机器和Win 7机器)都移到了工作组中，然后出现访问被拒绝错误.

但是所有其他WMI调用都可以正常工作(例如获取VM列表).

But all the other WMI calls are working fine(like get list of VMs).

                        ManagementScope范围= GetScope(hypervisorName，虚拟化");
                             WqlEventQuery查询=新的WqlEventQuery();
                             query.EventClassName =" __ InstanceModificationEvent" ;;
                             query.WithinInterval = new TimeSpan(0，0，5);
                             query.Condition =
                    "TargetTarget ISA'Msvm_ComputerSystem'AND TargetInstance.EnabledState = 2" ;;
                             watcherPowerOn =新的ManagementEventWatcher(作用域，查询);
                             watcherPowerOn.EventArrived + =新的EventArrivedEventHandler(watcher_EventArrived_RegisterVMPowerOnEvent);
                             watcherPowerOn.Start(); <--这里会引发异常 ！

               ManagementScope scope = GetScope(hypervisorName, "virtualization");
                WqlEventQuery query = new WqlEventQuery();
                query.EventClassName = "__InstanceModificationEvent";
                query.WithinInterval = new TimeSpan(0, 0, 5);
                query.Condition =
                    "TargetInstance ISA 'Msvm_ComputerSystem' AND TargetInstance.EnabledState = 2";
                watcherPowerOn = new ManagementEventWatcher(scope, query);               
                watcherPowerOn.EventArrived += new EventArrivedEventHandler(watcher_EventArrived_RegisterVMPowerOnEvent);
                watcherPowerOn.Start(); <- here it throws exception!

错误:访问被拒绝. (来自HRESULT的异常:0x80070005(E_ACCESSDENIED))

 

感谢您的帮助.
