If you enumerate dhcpd.leases for that subnet are all of them 'taken'?

Nope, I don't have a deny unknown. It's a subnet for handing out dynamic
dhcp to users in a particular vlan. The declaration is:
pool {
failover peer "pluto";
range 172.16.104.24 172.16.107.254;
allow unknown-clients;
}
This issue is sporadic and doesn't happen all the time. It just started this
morning.
Cheers
Matt

Do you have a 'deny unknown' statement in your configuration, and is that
MAC address listed?

HI all,
We keep getting:
DHCPDISCOVER from 00:15:c5:1c:21:d4 via 172.16.104.1: network 172.16.104/22:
no free leases
In our logs. We are running 2 servers in failover mode.
When we do a restart, we see the following, which indicates to me that there
*should* be leases available:
dhcpd: pool 90ecc98 172.16.104/22 total 999 free 483 backup 391 lts -46
Any help/advice is greatly appreciated.
Thanks
