一下是MSDN上一段代码,功能是执行远程主机上的CMD命令,但是却无法运行!
具体问题如下:
1、在执行
BSTR MethodName = SysAllocString(L"Create");
BSTR ClassName = SysAllocString(L"Win32_Process");IWbemClassObject* pClass = NULL;
hres = pSvc->GetObject(ClassName, 0, NULL, &pClass, NULL);
报错,pSvc->GetObject报错为ACCESSDENIED。
2、目标机器的未装防火墙,Windows自带防火墙也关闭了。
3、目标机器上的“简单文件共享”选项已经取消。
3、connectserver使用的是管理员帐号与口令。请问各位高手,这是怎么回事?我的QQ:47157860,万分感谢!

---估计目标机器的policy等不允许你这么做,或者OS的一些安全属性配置
你里面都是NULL。
