I have installed a clean Server 2012R2 server, joined it as a member server, installed RDS ran all patches. I am trying to set the IE Internet zone to medium High. The sites button is greyed. The Custom slider is not there. Custom Level button is available but the only Level available is High (default).
I have checked HKLM and HKCU for the Control Panel Internet settings. Keys/entries do not exist.
HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ Internet Explorer \ Control Panel
HKEY_LOCAL_MACHINE \ Software\ Policies \ Microsoft \ Internet Explorer \ Control Panel
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ CurrentVersion \ Internet Settings
I have verified no GPO Domain or local exists preventing changes.
I have set the registry value for the zone(s) to 1, no difference. Restarted server.
Added a Local GPO to allow changes (option is set to disable).
I'm at a loss now. Please help.
