On a Windows Vista-based client computer, you cannot obtain an IP address or options from the Dynamic Host Configuration Protocol (DHCP) server. Instead, the computer uses an Automatic Private IP Addressing (APIPA) IP address.
Note This problem does not occur in Windows XP or in Microsoft Windows 2000.
This problem occurs because the routing table in Windows Vista is more secure than the routing table in earlier versions of Windows. When the DHCP scope option for the default gateway has two entries that contain the same IP address, Windows Vista rejects the DHCP information.
To resolve this problem, modify the DHCP scope option for the default gateway to remove the duplicate IP address.
Note The DHCP scope option for the default gateway is 003 Router.
To modify the DHCP scope option for the default gateway, follow these steps:
The Windows Vista-based client computer uses an APIPA IP address to discover, offer, accept, and request DHCP information. Windows Vista cannot accept two or more default gateways in the DHCP scope option if the default gateways have entries that contain the same IP address.
