We found the problem. The culprit was a third-party application called PeerGuardian that was keeping the clients from obtaining an IP address. This was specific to our setup (and must be for other Cisco users) because the virtual IP address on all of our controllers is 1.1.1.1. In the DHCP offer, the packet was coming from source 1.1.1.1 and PeerGuardian had a problem with that IP address. Removing PeerGuardian solved our problem. We also tested with a valid virtual IP address and it worked.
