How to disable "Fix connection problems" button

[hoosierx]

I am currently working on kiosk and was doing good on locking it down until I discovered that if end user clicks on a broken link they get "This page can't be displayed".  The issue is when they get this page there is a "Fix connection problems" button on the page.  A user is able to click it and with some navigation can reach the control panel.

Is there a group policy, Registry setting or IE setting that will disable the "Fix connection problems" button?

Any help is greatly appreciated.

Restrict access to "C:\Windows\System32\msdt.exe", the actual diag tool, via GPO. The button will be there but will do nothing when clicked on.
