C#、WMI 和 Windows 7 与 Windows 2008 对话
我已经为此绞尽脑汁好几天了，但我不明白发生了什么事。我的开发盒是 Windows 7 64 位计算机，我尝试通过 WMI 连接到 Windows Server 2008 域控制器。
我的代码非常简单：
ConnectionOptions options = new ConnectionOptions();
options.Username = _username;
options.Password = _password;
options.EnablePrivileges = true;
options.Impersonation = ImpersonationLevel.Impersonate;
options.Authentication = AuthenticationLevel.Default;
ManagementScope scope = new ManagementScope(@"\\" + _hostip + @"\root\cimv2", options);
scope.Connect(); // this works!
ManagementEventWatcher watcher = new ManagementEventWatcher();
watcher.Scope = scope;
watcher.Query = new EventQuery(@"SELECT * FROM __InstanceCreationEvent WHERE TargetInstance ISA 'Win32_NTLogEvent' and TargetInstance.LogFile = 'Security'");
watcher.Start() // throws exception
watcher.WaitForNextEvent(); // works
我对 WMI 的了解有限，我无法弄清楚为什么 WaitForNextEvent() 有效但 Start() 无效。我不断收到的异常是：访问被拒绝。 （来自 HRESULT 的异常：0x80070005 (E_ACCESSDENIED)）
我已多次检查我尝试连接的域控制器是否设置正确（远程处理已打开、启用并具有权限），用户帐户也是如此我用的是连接。
任何想法和见解将不胜感激。
I have been racking my head over this for a couple days now and I cannot figure out what is going on. My dev box is a Windows 7 64-bit machine and I am trying to connect via WMI to a Windows Server 2008 domain controller.
My code is pretty simple:
ConnectionOptions options = new ConnectionOptions();
options.Username = _username;
options.Password = _password;
options.EnablePrivileges = true;
options.Impersonation = ImpersonationLevel.Impersonate;
options.Authentication = AuthenticationLevel.Default;
ManagementScope scope = new ManagementScope(@"\\" + _hostip + @"\root\cimv2", options);
scope.Connect(); // this works!
ManagementEventWatcher watcher = new ManagementEventWatcher();
watcher.Scope = scope;
watcher.Query = new EventQuery(@"SELECT * FROM __InstanceCreationEvent WHERE TargetInstance ISA 'Win32_NTLogEvent' and TargetInstance.LogFile = 'Security'");
watcher.Start() // throws exception
watcher.WaitForNextEvent(); // works
My knowledge of WMI is limited and I cannot figure out why WaitForNextEvent() works but Start() does not. The exception I keep getting is: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I've checked multiple times that the domain controller I'm attempting to connect to is set up properly (remoting is on, enabled and has permission) as is the user account I'm using to connect.
Any ideas and insight would be greatly appreciated.
