How do I stop DHCP giving out IP addresses to anything plugged into the network?
Posted on 2014-09-24
As a technology company which I am fairly new to, we seem to have a free for all attitude to plugging things into the network. I don't mind the hubs so much but three things I need to get on top of are virtual machines, mobile phones and self-purchased laptops. The latter is probably the one I need to resolve quickly. My problem is that anything plugged into our network will get an IP address and get access to certain resources - they have not been configured by me with anti-virus and computer accounts in AD, so my server screams at me with security failures which makes monitoring a nightmare. I think what I need to do is stop IP addresses being given to the devices above, but I am not sure how to do this.
