I maintain a large wide area network and use DHCP at many locations for roaming laptops etc. We occasionaly have outside laptops (contractors etc.) that are plugging into our network, getting an address and causing problems. They can’t get access to network resources, but the virus threat etc. is there. Asside from diabling the jacks we are not using, is there anyway to solve this situation and not allow foreign PC’s access to anything when they plug in? How are other companies handling this? Throw technology at it?
