How to programmatically add site to "Local Intranet" zone?
internet-explorer
Solution
It turned out that it is exactly the same as adding to 'Trusted Sites' (stackoverflow answer) but with setting the registry value to 1, not 2.
Problem
I've found out how to do it for Trusted Sites, but can't find for the Local Intranet. I'm talking about IE Security zones from Internet Options.
