Session expired page

Content

My LearnCenter is set to disconnect users after 120 minutes. If a user comes back to their session after this window and attempts to navigate they are redirected to a page which appears to allow them them to log back in. For some reason the login prompt does not authenticate so I was hoping to revise the page entirely.

I found the registry key which contains the "First Time Login Instructions" text and was going to replace it with a click here prompt that will take users to the correct login page. What I can't seem to locate is the key that generates the area in red. Users cannot authenticate through this area and I'd like to remove it.  Does anyone know how this can be done?
