Can we configure windows 2008 DHCP server to not ignore the broadcast falg of DHCP requests?
- by Mathieu Pagé
We have a Cisco WAP4410N access point that does not relay broadcast packets from the wired network to the wireless clients when the network is secured by WPA2. This cause problem with Windows server's DHCP server that respond to DHCP request by broadcasting it's OFFER instead of Unicasting it like it's asked by Windows (and Android and iOS) clients.
When we had a Windows 2003 server we configured the server not to ignore the broadcast flag (following these instructions) and it solved the problem. Now we upgraded our servers to Windows 2008 servers and the problem is back. Unfortunately, it seems Windows server 2008 ignore the IgnoreBroadcastFlag parameter.
Is there any other way to make sure that Windows Server 2008 respond to DHCP requests using Unicast instead of broadcast?
