活动目录,Windows 8

如果我使用用户“xxx”登录并使用这样的代码运行应用程序:

//WindowsIdentity.GetCurrent().Name - is "MyDomain\xxx";
var connectionOptions = new ConnectionOptions
{
  EnablePrivileges = true,
  Impersonation = ImpersonationLevel.Impersonate
};
var scope = new ManagementScope(
  string.Format("\\\\{0}\\root\\CIMV2", computerName),
  connectionOptions);
scope.Connect();

它运作良好。

但是,当在同一台机器上的 IIS 中运行此代码时,我遇到了异常:

// WindowsIdentity.GetCurrent().Name - is "NT AUTHORITY\SYSTEM" or "IIS APPPOOL\DefaultAppPool", tryed both
var windowsIdentity = User.Identity as WindowsIdentity;
if (windowsIdentity != null)
{
  using (windowsIdentity.Impersonate())
  {
    // WindowsIdentity.GetCurrent().Name - is "MyDomain\xxx";
    var connectionOptions = new ConnectionOptions
    {
      EnablePrivileges = true,
      Impersonation = ImpersonationLevel.Impersonate
    };
    var scope = new ManagementScope(
      string.Format("\\\\{0}\\root\\CIMV2", computerName),
      connectionOptions);
    scope.Connect(); 
    // throws exception "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))"
    // my other code here        
  }
}

使用的 Windows 身份验证:

<authentication mode="Windows" />
<identity impersonate="false" />

尝试将 AppPool 作为 ApplicationPoolIdentity 和作为系统运行。尝试为 AppPool 授予“作为操作系统的一部分”。结果是一样的,我总是得到“访问被拒绝”。

为什么我有这个例外?除了模拟或授予 AppPool 一些权限之外,我还应该做其他事情吗?
