I get this from the console of the 1130 AG when I reset the button on the AP. I tried giving the CISCO-LWAPP-CONTROLLER.nccvt.k12.de.us the ip address of the management server's AP point but no dice.

The other network could be a problem after you connect but I don't think it is your controller issue. Try the date and time fix first. Let me know how that works out. I think your option 43 is not working well. Use option 43 with the IP Address of the Controller. Also, make sure that all the ports on your switches are trunked for the approriate vlans. The answer with the 1131 resides in your controller or network but appears to be your Option 43. I would begin a TAC call on this if you have. They will have you run several LWAPP debugs. I am betting your dns entry or IP address of the controller is not correct. Look at your dns server and see what the name of the controller resolves to. If you are resolving to the AP Manager interface and not the management interface that would be the problem.
