我在 ISS 上部署网站时也遇到了同样的问题，但我从另一个页面获得了解决方案。

查看此页面 ....

Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path

我的解决方案是

->打开IIS管理器并选择应用程序池

->选择并右键单击池然后选择高级设置

->在process model下选择identity，改成LocalSystem。

->重新启动您的 IIS 或网站并浏览您的网页。

问题解决了......！
