INTRODUCTION

After a Microsoft Windows-based Dynamic Host Configuration Protocol (DHCP) client computer broadcasts a DHCP DISCOVER packet through a network segment, the computer ignores a BOOTP/DHCP REPLY packet that is sent in response by a Bootstrap Protocol (BOOTP) server in the same network segment. The BOOTP/DHCP REPLY packet is not processed.

MORE INFORMATION

After the DHCP client sends the DHCP DISCOVER packet, it waits for a DHCP OFFER packet in response. Other types of packets may not be processed.

According to Request for Comments (RFC) document 1534, a DHCP client computer must assume that an IP address that is returned in a message from a BOOTP server has an infinite lease. Also, a DHCP client computer must prefer a reply from a DHCP server to a reply from a BOOTP server. Therefore, even though the BOOTP/DHCP REPLY packet contains TCP/IP configuration information, this packet is considered unexpected and is not processed by the DHCP client computer.
