IIS 7無法創建ASPNETDB.MDF

Question

我有一個使用本地SQL Server Express數據庫（a.k.a.〜/ App_Data/ASPNETDB.MDF）的Web應用程序。

當我部署到IIS 7.0在Windows 2008標準版（SP2），我得到的錯誤：

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

錯誤消息繼續提供一些建議

SQLExpress database file auto-creation error:

The connection string specifies a local Sql Server Express instance using a database location within the application's App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:

1. If the application is running on either Windows 7 or Windows Server 2008R2, special configuration steps are necessary to enable automatic creation of the provider database. Additional information is available at: http://go.microsoft.com/fwlink/?LinkId=160102 . If the application's App_Data directory does not already exist, the web server account must have read and write access to the application's directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
2. If the application's App_Data directory already exists, the web server account only requires read and write access to the application's App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the application's App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server account's credentials are used when creating the new database.
3. Sql Server Express must be installed on the machine.
4. The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

我不瞭解如何解決4.（我在哪裏可以找到「自述文檔」？）。但是，其他項目看起來是正確的。

具體...

1. 有問題的應用程序池作爲網絡服務運行（不是應用程序池標識）
2. 的用戶使用網絡服務的App_Data已經完全控制（我理解正確的話，這確實並不需要讀/寫的App_Data的父母，因爲已經創建的App_Data？）

有趣的是，如果我副本 ASPNETDB.MDF和ASPNETDB.LDF從我的開發機器的生產圖片在App_Data上，錯誤更改：

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

我錯過了什麼？

Answer 1

我最終將相關表移動到新的SQL Server數據庫，因爲我無法解決權限問題。

無論如何，對於生產應用程序來說，這是推薦的方法，但似乎不幸的是，它很難（在確定如何配置安全性方面）爲小量網站部署ASPNETDB.MDF變體。

Answer 2

我以前有同樣的錯誤，問題是我的SQL Server服務已停止，這是非常奇怪的，但有時他們只是崩潰，我不得不重新安裝SQL Server導致服務甚至沒有讓我啓動它，所以你可能想檢查一下。
