I have a computer on a domained network, running Windows 7 Pro, IE 11. When I try to open HTTPS sites, it says to check the web address. I can log onto the domain on the same computer as the administrator and the same HTTPS sites open correctly. I thought it may be an issue with the user profile so I unjoined the domain, rejoined the domain, rebuilt the user profile, and same thing. I removed AV and turned off firewall to see if this made any difference, it didn't. Any ideas as to what could be causing this?
