FullTrust 的安全问题

Question

我在网络共享上有一个 .NET2.0 程序集供每个人访问。我已在每个人的计算机上为 LocalIntranetZone 启用 FullTrust。

然而，在某些机器上（不是全部……这就是让我发疯的部分）应用程序崩溃了。我得到的错误如下。

我现在完全被难住了。任何想法将不胜感激。

Answer 1

问题是发生故障的区域不是您的 LocalIntranetZone，而是出于某种原因的 Internet 区域。

失败的程序集的区域
是：互联网

如果它只发生在某些计算机上，我会检查您的网络拓扑，因为听起来您的某些计算机在运行您的应用程序时试图访问您的内部网之外。
