While trying to solve my computer clock always running ahead (even when on, not just on every boot), I apparently broke some security settings.
All I did (as far as I can remember) was stop and start the w32time service.
Now, whenever I go to the "Internet time" tab, and click "Change settings..." Windows tells me I don't have permissions to do so.
- I am a member of the Administrators group.
- In gpedit.msc, I checked that the Administrators group is allowed to change the system time.
