Why does DNS stop working across the domain after an update?

An update causes DNS to stop working across the entire domain and triggers an "Access Denied" error when trying to open dnsmgmt.msc. This failure prevents proper domain management and causes DNS to repeatedly stop working upon reboot, even though internet connectivity remains functional.
