Most Internet Service Providers use DHCP to assign new IP addresses to client computers when a customer connects to the internet - this simplifies things at user level. and, you can easily check for 'rogue' DHCP servers using Wireshark (or Ethereal as is used to be called). You shouldn't, and can't disable the firewall on SBS client machines bacause it is controlled by an SBS domain policy.

You are able to add an exclusion by right clicking the address pool text on the left hand side of the mmc window and selecting "new exclusion range". You could also install wireshark or similar on the SBS and a test laptop to get visibility of the dhcp requests.
