We are running a MS DHCP network and home wireless routers are finding their way in. I scan the DHCP scopes daily and thought I was denying their ability to connect by creating a reservation for the MAC address and modifying the configuration options for the device. I set the following options to 127.0.0.1: 003-Router, 005-Name Servers, 006-DNS Servers and 044-Wins/NBNS Servers. I also changed option 015-Domain Name to "blank". This work on rogue laptops that use wired ethernet, but the wireless routers still seem to ba able to give network access to any computer connecting to them. How can I configure DHCP to deny rogue devices from obtaining IP's and passing that access to their clients?
Thanks in advance
