Most likely, the client computer did not supply a name when making its DHCP request.

For Linux boxes, either go through the GUI and supply a hostname in the DHCP section. If you want to edit files directly, look at your /etc/sysconfig/network-scripts/ifcfg-* files. You need to add:
DHCP_HOSTNAME={computer_name}
for the appropriate network interface.
