We are using Windows for DHCP and have two controllers. We are in the middle of testing for a re-addressing project and can only get APs local to the 1st controller, who's address is handed out with Option 78, to work when changing subnets. I can add the two controllers to each AP, or make the APs local to the first controller before flipping them, but was hoping to do it a little more gracefully than that. I haven't found much good documentation on Option 78 in Windows. Is it possible to add a 2nd address using Option 78 in Windows Server?
