与SQL Server Express用户实例和ASP.net Web应用程序项目（DOTNET核弹）

Question

问题我想通过DotNetNuke的连接到SQL Express 2005。我的操作系统是Windows 7（IIS 7），当我试图连接我得到了以下错误：

An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

我已经试过我在下面的链接找到了解决办法，但我仍然得到同样的错误。

然后我试图在我的SQL Server名称更改从SYSTEMNAME\SQLEXPRESS到SystemIP\SQLEXPRESS我得到一个DotNetNuke的错误如下：

DotNetNuke的错误

任何一个可以帮助我解决这个问题？

Answer 1

有类似问题，发现我不得不升级到SQLExpress 2008R2，因为示例数据库在2008R2，我只有2008 Sp1安装。

关键是另一条消息：“数据库C:\USERS\....\APP_DATA\ASPNETDB.MDF无法打开，因为它是version 661。此服务器支持version 655及更早版本，不支持降级路径。”

Answer 2

我想这在IIS7，和它的工作：

在ApplicationPools->DefaultAppPool->Advanced Settings...，在Process Model部分，我的Identity酒店需要从下拉列表中设置到LocalSystem。为DotNetNuke优选设置是NetworkService。

的LocalSystem设置工作，因为代码将使用用于登录到计算机的本地身份连接到SQL Server。如果该登录名在Sql Server中配置为登录名，则这是必需的。我认为，如果SQL Server登录/身份相应的修改，NetworkService设置也应该工作（我没有试过）。
