A DHCP Client May Send an Incorrect FQDN in a DHCP-Request Packet (317288)

The information in this article applies to:

Microsoft Windows XP Home Edition
Microsoft Windows XP Professional

This article was previously published under Q317288

SYMPTOMS

A Dynamic Host Configuration Protocol (DHCP) client may send an incorrect fully qualified domain name (FQDN) in the DHCP-Request packet in option field 81. The client may send the primary domain suffix instead of the connection-specific domain suffix, even though the "Register DNS records with connection-specific DNS suffix" policy has been turned on. When this situation occurs, you see an incorrect FQDN in the Name column if you look at the address lease on the DHCP server.

CAUSE

This behavior occurs because the DHCP client is not parsing policy settings correctly.
