You need to give the ASPNET user access to the database or impersonate a user that already has database access. You can impersonate another user by adding this line to the web.config:

<identity impersonate="true" userName="CO-B080FE8CE82C\database_user" password="dbpassword"/>

Also, giving the ASPNET user access to resources (such as a database) can be a security risk, so I would recommend impersonating another user.

A second option would be to use SQL User Authentication instead of an SSPI context.

Thanks.

To use SQL User Authentication, your sql server must be setup to support it. If it is, simply change your connection string to something like:

"server=CO-B080FE8CE82C;user id=sqluser;password=mypassword;initial catalog=PizzaStore;"

Where sqluser and mypassword are the user credentials for your sql user.

I added a new user using Enterprize Manager .. User = pizza ; password= pwpizza
but it gives another error :

Login failed for user 'pizza'. Reason: Not associated with a trusted SQL Server connection.

this.sqlConnection1.ConnectionString = "data source=CO-B080FE8CE82C;initial catalog=PizzaStore;user id=pizza; Password=pwpizza";

sorry for this stupid question :(

Try this:

1) Open Enterprise Manager.
2) Right-click on the SQL server instance
3) Choose "Properties" from the context menu. The "SQL Server Properties (Configure)" window will open
4) Choose the "Security" tab and make sure that under the "Authentication" header that "SQL Server and Windows" is selected.

That will enable SQL Server authentication so that your connection string will work.

Thanks.
