A client will try to renew it's address when it is restarted,
when ipconfig /renew is issued or when it reaches 50% of it's lease
duration. If it fails during the last it will try again at 87% of the
lease
duration.

This would not be likely. What is most likely occuring is that an
alternate
cofiguration has been added to the machines that seem to be renewing
sans
the DHCP server. I have had to do this in some really trashed networks
to
provide addresses for clients while fixing a DHCP server.

I can't explain why your clients aren't doing what they are supposed to
be
doing without more information.

The client in a restart is requesting a renewal, it is not issuing a
release.
