Is 5 minutes after you post soon enough? :-)

Is it obvious that there could be trillions of reasons? Our access to your hard drive is somewhat limited :-)

The is not a valid question, and it is not answerable. Needs more information.

1. Try to put your data base in application's App_Data folder.
2. If this doesn't work than try to use this connection string below, if you created database by sql server management studio express.
Data Source=.\SQLEXPRESS;Initial Catalog=CarRent;Integrated Security=True
3. Even if all this doesn't help than try to delete already existed database from sql server but please take a backup,So when there is no attached database,It'll work fine absolutely.
