A DHCP client that is running Windows Server 2003 may send an incorrect FQDN in a DHCP-Request packet

When you use a Dynamic Host Configuration Protocol (DHCP) client that is running Microsoft Windows Server 2003, the client may send an incorrect fully qualified domain name (FQDN) to the DHCP server in the option field of a DHCP-Request packet. 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 setting is enabled. When this problem occurs, you see an incorrect FQDN in the Name column of the DHCP server's address lease record for the DHCP client.
