An attempt to attach an auto-named database for file...failed. A database with the same name exi

I know allot of folks are having this problem and I tried lots of things but nothing works. I understand the problem is coping the SQL Express on another server is the problem - I just not sure what to do?

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

This is the last statement on the Stack Trace:

SqlException (0x80131904): An attempt to attach an auto-named database for file e:\wwwdata\81d0493f\www\App_Data\TestDatabase.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.]
System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) +735091

I checked my server forum and they said I had to name a database:
Example: Database=(unique name);

But this didn't work either.

I just tried a simple web project that has only one database and one table in SQL Express with one sqldatasource and one datagrid. It works fine on my pc but when I use the copy function in Visio Studio 2005 Pro - I can't run the site on the remote server: www.myjewelrydirect.com

I tried coping the database manually. I tried disconnecting the database before I copy it. Below is my connection statement:

<connectionStrings>
<add name="TestDB" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\TestDatabase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>

With all the comments in these forums - this must be a bug.

I have been working on this problem for over 2 weeks - HELP!

Since this is a web app, it is probably running under the ASPNET user account. Make sure that the ASPNET user, or what ever user your appliction is running under if you've set up something other than the default, has permissions on the directory where the database is located.

If the user doesn't have permissions to the directory, you can't attach the database.
