Sql Configuration Problems (Desperately In Need Of Help)

Hi

I am currently working on my final year project for uni using vs 2005, sql server express and xp pro sp2.

Basically I created a website in asp.net and created a database in the app_data directory.

Everything was working fine up until last week until I downloaded sql server management studio. I was experimenting with the IDE and attached the database from the app_data directory of the website to the sqlserver management studio.

Ever since I havent been able to connect to the database and am very worried about it as I have spent a week tearing my hair out to no avail.

The error I am getting is:


Server Error in '/WebSite/Iftams Project' Application.


Cannot open user default database. Login failed.
Login failed for user 'RODNEY-DESKASPNET'.

I believe that the connection string in my web.config is looking for the database in the app_data folder however the default database (whatever this means) is not set to the database I have or else the aspnet user is not allowed to see the database because ssms has corrupted the settings.

Please help!
