I have a working dnn site.  I've created several modules and corresponding tables in the database and everything works great.  Then, I open SQL Server Management Studio Express, attach to the database, backup the database, detach from the database and I can no longer attach to the db from dnn (error shown below).  I can open the database from Visual Studio and see my tables, but I cannot run the application.  Rebooting doesn't help.  I've even tried copying over the database with a prior copy.  It still doesn't work.  The only way I have found to reconnect to the database is to copy over the entire dotnetnuke install directory with a copy I made prior to the backup.  Then it works again. 

Anyone else had this behavior?  How do I fix it?

Thanks

Mark

This could be a "schema" (databaseowner) issue.

        <add name="SqlDataProvider" type="DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider" connectionStringName="SiteSqlServer" upgradeConnectionString="" providerPath="~\Providers\DataProviders\SqlDataProvider\" objectQualifier="dnn_" databaseOwner="dbo" />
Check on your database and web.config file which is the configured value ("dbo" by default, but I guess is another in your case) and check on the database that the schema exists and has the right permissions.

HTH,

Here's the solution to the database connection problem I experienced after attaching the Database.mdf file with SQL Server Management Studio Express.

Hope this helps.

Thanks Horatio.  I'm not sure how to check permission on the schema.  My web.config connection strings (below) do not specify a db owner.  Do they need to?  I can connect with VS 2005 Server Explorer after I modify with SQL Express Manager, but I cannot connect with dnn site. 

<add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ParaPro.mdb;" providerName="System.Data.SqlClient"/> 

<

Thanks for your help. 

add key="SiteSqlServer" value="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|ParaPro.mdb;"/>

Thanks for your help also.  I followed the article, but I still get the same error.  When you modified the attached name did you keep the .mdf extension on the name?
