Dhcp Server problem


Hi there..


Im sysadmin, at a university and some students are working whit vmware creating dhcp and dns Servers for a task.

If you are using active directory, you can make only authoritive dhcp and dns servers "work"

Create a separate VLAN and create an ACL to block port 68 and 53 from coming across

If someone installs a dns server it can't do much damage. Don't know of a way to block a dhcp server if it is on the same subnet.
