java连接到远程计算机以获得WMI支持

Question

我正在尝试使用java和Jacob连接到远程计算机，以获取有关远程计算机的一些WMI信息

对于localhost，我使用下面的代码，效果很好

    String host = "localhost";
    String connectStr = String.format("winmgmts:\\\\%s\\root\\CIMV2", host);

    ActiveXComponent axWMI = new ActiveXComponent(connectStr);
    // other code to get system information

但如果我将localhost更改为另一个ip/主机名，则会出现以下错误：

Exception in thread "main" com.jacob.com.ComFailException: Can't find moniker
    at com.jacob.com.Dispatch.createInstanceNative(Native Method)
    at com.jacob.com.Dispatch.<init>(Dispatch.java:99)
    at com.jacob.activeX.ActiveXComponent.<init>(ActiveXComponent.java:58)
    at easyticket.classes.WmiExtended.main(WmiExtended.java:28)

引发异常的行是：

ActiveXComponent axWMI = new ActiveXComponent(connectStr);

编辑

我尝试使用WbemScripting传递用户名/密码

String host = "192.168.7.106";
ActiveXComponent axWMI = new ActiveXComponent("WbemScripting.SWbemLocator");
axWMI.invoke("ConnectServer", new Variant(host+",\"root\\cimv2\",\"username\",\"password\""));

但我犯了一个错误：

Exception in thread "main" com.jacob.com.ComFailException: Invoke of: ConnectServer
Source: SWbemLocator
Description: The RPC server is unavailable. 

我该如何解决？如何传递用户名/密码？如果需要，如何传递域

我正在使用Windows 8，我正在尝试连接到win8/win7/winxp/win2003server计算机

经过一些搜索，我设法解决了我的问题

这是密码，如果有人需要的话

ActiveXComponent wmi = new ActiveXComponent("WbemScripting.SWbemLocator");        

  Variant variantParameters[] = new Variant[4];
  variantParameters[0] = new Variant(_IPADDRESS);
  variantParameters[1] = new Variant("root\\cimv2");
  variantParameters[2] = new Variant("username");
  variantParameters[3] = new Variant("password");     
  ActiveXComponent axWMI;
try
{
    Variant conRet = wmi.invoke("ConnectServer", variantParameters);        
    axWMI = new ActiveXComponent(conRet.toDispatch());
}catch(ComFailException e)
{
    axWMI = null;
}
if (axWMI == null)
    return false;
