Computer name not appearing in DHCP lease

We were seeing a problem where some DHCP leases were not showing the computer name.  None of these machines with blank lease names would show up in DNS.

It turned out that each of the machines with blank DHCP lease names were Macs and they had different sharing names than the computer names there were bound to the AD with.

The solution was to make the sharing name the same as the AD computer name.  As soon as this was done and the computer was restarted the machine appeared in DNS and the DHCP lease had the proper name associated with it.
