重新安装SQL Server后从网络共享中访问SQL Server的问题

Question

我有一个问题，那真的让我发疯。

首先我必须承认，大部分的工作都是由一个不再可用的同事完成的。

重新安装MSSQL服务器钻机之前，整个事情看起来就像是：

• 有人开发了一个连接到SQL Server的一个小的.Net C＃程序，即位于不同的网络共享。一切工作

我们不得不重新安装服务器（Windows + SQL Server）的，自那一刻，如果程序是从网络共享运行，我得到以下错误：

"Unhandled Exception: System.Security.SecurityException: Request for the permissi on of type 'System.Data.SqlClient.SqlClientPermission, System.Data, ......"

如果我从共享所在的计算机本地运行程序，它工作正常 - 所以我猜想所有安全问题都在SQL Server上正确设置。但是必须有一个问题，因为它在重新安装之前工作正确。

这对某人有意义吗？或者有什么想法如何解决这个问题？

编辑：下面张贴错误消息。该程序由批处理脚本调用。

这是一个.NET安全问题。它将来自网络共享的应用程序视为与本地文件夹不同。

现在我不确定我们过去如何解决这个问题，但请尝试以下操作：在调用计算机（而不是服务器）上使用.Net向导为该程序（= Assembly）设置手动信任从控制面板，使用\ server \ share \程序进行导航。

我想你可以通过改变安全级别/区域来使它工作。
