Configure Windows7 prefer DHCP unicast or broadcast response

預設上Windows7 Home edition是prefer DHCP Server回應的封包採用broadcast的方式,當然這也是可以更改為unicast的,做法很簡單,只要透過register table來更改就可以完成了。

Click Start->regedit->

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

GUID這邊指的是對應到的NIC,可用wireshark來幫助查詢。

DhcpConnForceBroadcastFlag (0 or 1)

0 indicate unicast

1 indicate broadcast
