dhcp server gives new lease to machines that reboot.

[Gregory Machin]

Hi.

I'm at a lost I have dhcp client machine that are rebooted 2 to 3
times a day as part of testing. I can see no errors in the dhcp logs
that would indicate an issue. The logging on the client machine
doesn't give any useful information either.

The logs on the dhcp server :

Dhcpd.conf for the range in question.

What could be the issue ?

Thanks
