6. Enter a database name and grant access to the user you created above and click Save. In this demonstration the database is called DotNetAuthentication.

7. Locate and run the ASP.NET SQL Server Setup Wizard. This file is located in your .NET framework directory and is named aspnet_regsql.exe (example: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regsql.exe).

8. Click Next and choose Configure SQL Server for application services.
