Hi Mike,
Does the display really say "Access Denied", or does it say "Denied in Admin"?
Just a couple of thoughts:
Check for a Ringing Service key on 228 (F 871). If it is no longer the Control set, you can get rid of that key.
Also, check for a stuck button on 228.
Your software is 4.1. Do you know which Production Version it is? It will be something in the range of G00-G15. If it is G00, think about replacing that feature cartridge.
If everything looks OK, and all that you've done is change the Control set, you might try cycling the power on the system (do a backup first).
Hope that helps!
