re: Login failed for user '\ASPNET' error

Have you been into sql server and set up the logins and permissions that you want to use?

You need to allow the ASPNET windows user account access to your SQL Server. Alternatively, you can create a Sql Server account inside the Sql Server, and provide a username and password in your connection string.
