This feature, however, brings with it challenges for individuals and organizations alike. It creates a mechanism that can be used by users of the network (e.g., children) to circumvent the controls deployed to filter content.

To help, we have created a file that can be used to disable DOH in the three common browsers – Chrome, Firefox and Microsoft Edge. This configuration does require a reboot, please be sure to close all apps before starting so that you can safely reboot after configuring.
