Ryan, Not directly related to DHCP...
We have been enabling BPDUgard on Cisco switches, on the Wired side. At least if people are bridging, it kills the Wired side. (you don't want to enable BPDU on the Wireless side!) That fixes bridging. We also disable manually IPv6 on Vista machines, since it seems that it creates a lot of conflicts (DNS and Gateway).
