IIS + WMI：无法获取所有 WMI 信息

我正在尝试创建一个网络服务（WCF）来获取有关我的服务器的信息。我为 WMI 做了一个类，它可以检索有关 cpu、ram、磁盘等的信息...

在 Visual Studio 下，该服务工作正常，但是当我在 IIS 上部署该服务时，我得到了所有信息...除了一个！我有一个硬盘有两个分区（C 和 D），当我部署到 IIS 时，当我尝试检索第二个分区的“大小”时出现错误。该代码在控制台应用程序中运行良好。我也尝试过使用简单的 ASP.Net 网站而不是 WCF，也不起作用。

这是我使用的代码：

    ConnectionOptions aCO { get; set; }
    ManagementScope aMS { get; set; }

    public Wmi()
    {
        aCO = new ConnectionOptions();
        aMS = new ManagementScope("\\\\localhost", aCO);
    }
    .....
    ObjectQuery aQ = new ObjectQuery("select Name,Size,FreeSpace from Win32_LogicalDisk where DriveType=3");
    .....
    foreach (ManagementObject oReturn in aRToSet)
        {
                string letter = oReturn["Name"].ToString();
                long size = long.Parse(oReturn["Size"].ToString());
        }

我做了一些测试，该服务在我的计算机（带有 IIS 7.5 的 Windows 7）上运行，但在我的服务器（Windows Server 2008）上运行不正常。

有人能给我任何线索吗？

谢谢。

I'm trying to make a webservice (WCF) to get information about my server. I made a class for WMI who can retreive information about cpu, ram, disks, etc...

Under visual studio, the service works fine, but when I deploy the service on IIS, I get all the information ... Except one ! I have one hard disk with two partition (C & D), when I deploy to IIS, there is an error when I try to retreive the "Size" of the second partition. The code works fine with a console application. I tried also with a simple ASP.Net website instead of WCF, doesn't work either.

Here is the code I use :

    ConnectionOptions aCO { get; set; }
    ManagementScope aMS { get; set; }

    public Wmi()
    {
        aCO = new ConnectionOptions();
        aMS = new ManagementScope("\\\\localhost", aCO);
    }
    .....
    ObjectQuery aQ = new ObjectQuery("select Name,Size,FreeSpace from Win32_LogicalDisk where DriveType=3");
    .....
    foreach (ManagementObject oReturn in aRToSet)
        {
                string letter = oReturn["Name"].ToString();
                long size = long.Parse(oReturn["Size"].ToString());
        }

I made some tests, the service works on my computer (windows 7 with IIS 7.5) but not on my server (Windows Server 2008).

Could someone give me any clue ?

Thanks.
