重新安裝SQL Server後從網絡共享中訪問SQL Server的問題

Question

我有一個問題，那真的讓我發瘋。

首先我必須承認，大部分的工作都是由一個不再可用的同事完成的。

重新安裝MSSQL服務器鑽機之前，整個事情看起來就像是：

• 有人開發了一個連接到SQL Server的一個小的.Net C＃程序，即位於不同的網絡共享。一切工作

我們不得不重新安裝服務器（Windows + SQL Server）的，自那一刻，如果程序是從網絡共享運行，我得到以下錯誤：

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

如果我從共享所在的計算機本地運行程序，它工作正常 - 所以我猜想所有安全問題都在SQL Server上正確設置。但是必須有一個問題，因爲它在重新安裝之前工作正確。

這對某人有意義嗎？或者有什麼想法如何解決這個問題？

編輯：下面張貼錯誤消息。該程序由批處理腳本調用。

這是一個.NET安全問題。它將來自網絡共享的應用程序視爲與本地文件夾不同。

現在我不確定我們過去如何解決這個問題，但請嘗試以下操作：在調用計算機（而不是服務器）上使用.Net嚮導爲該程序（= Assembly）設置手動信任從控制面板，使用\ server \ share \程序進行導航。

我想你可以通過改變安全級別/區域來使它工作。
