SubscribeWindows Vista is Unable to Get DHCP IP Address
Posted on Nov 19, 2007 under Windows Vista Tips |Windows Vista may be unable to obtain an IP address using DHCP.
This issue occurs because of a difference in design between Windows Vista and Microsoft Windows XP Service Pack 2 (SP2). Specifically, in Windows XP SP2, the BROADCAST flag in DHCP discovery packets is set to 0 (disabled). In Windows Vista, the BROADCAST flag in DHCP discovery packets is not disabled. Therefore, some routers and some non-Microsoft DHCP servers cannot process the DHCP discovery packets.
