hi all
i'm new here. only some PCs in my company are allowed to access internet, others not. all approved PCs come with a gateway address. there is a policy from server blocks users from changing there connection settings. my question is: if someone in my company brings in a laptop and he adds the gateway, he can use internet. how can i know if he does it? how can i prevent PCs that not in our domain from adding the gateway?
of course in theory, the answer for both questions is yes. but how to do it?
