Amazing! So as a malicious employee, all I have to do is run a DHCP server that dishes out host names with the adress leases and then AD will be ruined as DNS records will be wrong and computers won't match their accounts in AD?
Boxes that are members of an AD will not accept leases from a dhcp server that has not been authorized as a dhcp server in the AD.
This setup is for a home network of stand-alone boxes.
And at the end of the article, they are also leasing addresses to Linux boxes and checking whether they are successful in the dhclient-ethX.leases file.
