Windows Vista cannot obtain an IP Address from certain routers or from certain non-Microsoft DHCP servers
Consider the following scenario:
- You connect a Windows Vista-based computer to a network.
- A router or other device that is configured as a Dynamic Host Configuration Protocol (DHCP) server is configured on the network.
- The router or the other device does not support the DHCP BROADCAST flag.
In this scenario, Windows Vista cannot obtain an IP address.

Requirements for Internet Hosts — Communication Layers (RFC 1122, R. Braden, Oct 89):
The IP layer MUST provide a means for the transport layer to set the TTL field of every datagram that is sent. When a fixed TTL value is used, it MUST be configurable. The current suggested value will be published in the “Assigned Numbers” RFC.
A fixed value must be at least big enough for the Internet “diameter,” i.e., the longest possible path. A reasonable value is about twice the diameter, to allow for continued Internet growth.
Assigned Numbers (RFC 1700, J. Reynolds, J. Postel, October 1994):
IP TIME TO LIVE PARAMETER
The current recommended default time to live (TTL) for the
Internet Protocol (IP) [45,105] is 64.
