windows 2008 x64 使用RAS Administration DLL

Question

我找到了一个RAS Administration DLL 的例子，默认编译是x86的dll，在win2k3上使用正常，放到2k8上报告不是有效的 win32 应用程序。

把工程改为x64模式编译会报错

代码如下：

UserRestrict.h

我是搞c#的， 对c++ 不太熟悉，老解决不了问题，请高手帮忙解决。谢谢。

 

Answer 1

你在2008下用32位方式编译一下应该就可以了

Answer 2

我现在编译成x64 和x86 都可以了，引用的lib不一样，但是，部署到windows 2008 r2 服务器，会报告

 

无法加载第三厂商的 RAS 管理 DLL 组件。发生下列错误: 找不到指定的模块。

 

我在windows 2003 32位上 测试没问题，

Answer 3

Hi max，

>>无法加载第三厂商的 RAS 管理 DLL 组件。发生下列错误: 找不到指定的模块。

这很可能是服务器的问题。您的服务器没安装第三方组件。
