Question

我有一个问题，这真让我疯狂。

首先，我必须承认，大多数工作都是由一位不再可用的同事完成的。

在重新安装MSSQL Server装备之前，整个过程看起来像这样：

有人开发了一个连接到SQL Server的.Net c＃程序，该程序位于不同的网络共享上。一切正常

我们不得不重新安装服务器（Windows + SQL Server），从那时起，如果程序是从该网络共享运行的，我会收到以下错误：

“未处理的例外情况： System.Security.SecurityException：请求类型的许可 “System.Data.SqlClient.SqlClientPermission， System.Data，......“

如果我从共享所在的计算机本地运行程序，它可以工作 - 所以我想所有安全问题都放在SQL Server上。但是必须有一个问题，因为它在重新安装之前工作正常。

这对某人有意义吗？或者任何想法如何解决？

编辑：发布以下错误消息。该程序由批处理脚本调用。

Answer 1

这是一个.NET-Security-Issue。它处理的网络共享中的应用程序与本地文件夹不同。

现在我不确定我们过去是如何解决这个问题的，但请尝试以下方法：在调用计算机（而不是服务器）上使用.Net向导设置对此程序（=程序集）的手动信任控制面板，使用\ server \ share \ program进行导航。

我认为您也可以通过更改安全级别/区域来实现它。
