Internet explorer security settings
Posted on 2013-11-13
Firstly, windows 7 machines with mixture of IE10 and IE9.
machines have been having problems with scripts not running at login, exe files not allowed to run, some documents not allowed to be opened and now a lot of internet sites will not open or say that the machine does have java or flash installed.
these errors all come with an internet security warning stating that the settings do not allow these files to be run/accessed. PROBLEM: internet security settings are set to HIGH.
if I reset internet explorer back to defaults everything works, unfortunately after a reboot or the next user logs in or even after a couple of hours of the machine being on the settings revert back to HIGH instead of Medium-High.
nothing is set in any GPO that could affect this setting and it has only started happening over the past week.
Anybody have any idea what's causing this to happen? I can only assume it must be an update from Microsoft but which one?
