Set Application Name In Web.config

Hi,
I am a bit stuck. I have an application I created and it works fine locally and when on the demo server. However, when placed on the test production server users are unable to login. I think this is to do with the application name not being set in the web.config. But the aspnet_Applications table in the database is empty. I can get the application_id from the dbo.Applications and the dbo.Memberships table. But when I try to manually add the applicationname to the database and reference it in the web.config, I cannot login locally. 

The ApplicationId is "99E92642-4CB1-474C-9E11-E2588382C4EC". 
So I added that to the aspnet_Applications table along with the applicationName as "/ReadyXXX" and loweredApplicationName as "/readyxxx". These are just sample application names. But when I update the web.config to use that application name I cannot login.
