我有一个在Visual Studio 2017中开发的.NET应用程序，部署到IIS(7.5版(服务器上，经过一年的正常工作，在我发布到生产环境后，该服务器现在收到以下错误：
对象"[表名]"、数据库"[数据库名]"和架构"dbo"的UPDATE权限被拒绝
对应用程序所做的唯一更改是更新.aspx页面中的HTML链接。
在IIS中，我使用以下设置创建了一个自定义应用程序池：
Name: Safety App Pool
.NET Framework: v4.0
Managed Pipeline Mode: Integrated
Identity: ApplicationPoolIdentity
在SQL Server中，我为IIS APPPOOL\Safety App Pool设置了安全登录，并将其添加到数据库的用户中，并明确授予该用户对数据库的连接、删除、执行、插入、选择和更新权限。记住，就在一周前，这个设置还不错。我上周三发表了这篇文章，然后休了几天年假(当然(，回来后发现人们无法从网站上进行更新或插入。
真正奇怪的是，即使我将应用程序池更改为另一个当前仍在工作并能够更新/插入到同一数据库的应用程序池，我仍然会得到这个特定应用程序无法得到的错误。这就是为什么我认为web.config文件中存在某些设置，或者Visual Studio在发布过程中专门做的某些设置导致了问题。然而，在上周投入生产之前，我没有对任何配置/发布文件进行任何更改。我已经复制并粘贴了应用程序事件日志中显示的错误：
