安装Hudson 2.1作为服务

Question

用hudson运行后：

C:\Documents and Settings\senna\.hudson>java -jar hudson.war

并导航：http://mymachine:8080/install/?

错误：

Installing a service

[.hudson] $ "C:\Documents and Settings\senna\.hudson\hudson.exe" install
System.Management.ManagementException: Initialization failure 
   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
   at System.Management.ManagementScope.InitializeGuts(Object o)
   at System.Management.ManagementScope.Initialize()
   at System.Management.ManagementScope.Connect()

   at WMI.WmiRoot..ctor()
   at winsw.WrapperService.Run(String[] _args)
   at winsw.WrapperService.Main(String[] args)

有什么不对？
