Yes they're factory pressed Windows administrators who are to be honest fucking useless unless it comes to pointing at someone else but that's another story...they're being replaced piecemeal by bits of Ansible and Linux machines.

Realistically we don't want to deploy a host file and AFAIK it doesn't work anyway; we want to control the network itself which we do via firewalls and DNS but it's a compromise between flexibility (our users still need to use the internet) and security.
