Problems deploying ASP.NET 4 app to Web Server

I just created my first ASP.NET Version 4 app using Visual Studio 2010 and SQL Express 2008.

I copied the files to IIS and run the default.asp. This loads the programs main menu. So far so good.

When I open the read webform and do a read of my database I get the following Error:

Server Error in '/Diary' Application.

Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed.

Any idea how to fix开发者_如何学Go this error?
