How do I add ASPNET user to SQLExpress DB?

I am going though the ASP.NET QuickStart tutorials. One of the lessons is to add a datagrid. I am able to do that with VWD and am able to connect to the database in VWD. However when I try to execute the application I get a "Login failure" message because the user pcName/ASPNET cannot login.

How do I add the ASPNET user to the SQLExpress database? There don't seem to be any administration tools that were installed with SQL Server Express 2005.

Thanks in advance for the help!

There are two permissions to SQL Server the Server permissions under security in Management in Management Studio and the new security section within the database. The management tools are a separate download. Hope this helps.
