Not enough information! Use SQL credentials - user id and password registered in SQL server, do NOT use integrated security. Create the user for your app in SQL server eg userid - MyAppUser Give the user dbo rights to your database Use those credentials in your connection string. If this does not make sense to you then get a book or an article and work through the examples.

What help do you need? The error tells you exactly what the problem is.
