How can I prevent a duplicate DHCP server on a network from interfering? Is it possible?
I am not asking for any actual scenario that is happening, just curiosity. In my apartment complex there is a network and internet provided, someone caused problems with the entire network because they plugged in their wireless router which had a DHCP server enabled.
How would you prevent such conflicts / problems on a network, or it is impossible short of firewalling and controling the machines on your network?
