Multiple leases

We have a number of laboratories with Mac computers, all Tiger I

We have an issue where the Macs seem to consume multiple leases during
their boot process and the IP number they end up with doesn't always
make it into the DNS for some reason.  This is proving to be a head-ache
for those trying to manage the environment as often the DNS name does
not resolve to the correct (currently allocated) lease. There is no
shortage of leases in these networks. I have a similar situation in our
PC labs where a PXE boot consumes a different lease from the normal
Windows boot that follows <30 secs later.

How can one force a client to be recognised as the same, the MAC Address
is not changing. I have included 'deny duplicates' in each subnet
definition but that doesn't appear to have helped. I want the same lease
re-allocated during the boot process so that the DNS entry is correct.
