BOOTP from dynamic client and no dynamic leases

Hello,

I'm searching for help in resolving the issue that manifests itself
with the error message, "BOOTP from dynamic client and no dynamic
leases," in my new dhcpd server setup.  This server is only to service
bootp clients, though these clients aren't actually using bootp to
boot anythng they're just getting an IP address, and I continually get
this error.  My IP setup is where I work and I don't run the IT
situations.  My team regularly changes hardware and to meet the demand
we were given a small block of IP within the subnet in which we
operate to use on a local bootp server.  Our existing server is having
problems and is dying a dramatic death.

Anyway, I'm desperately trying to setup a new server.  I cannot share
the full text of my config file, sorry because I know that's what
everyone would prefer.  Below shows what's in there but is edited to
remove our host names and IP addresses.  As I mentioned I have a small
block within the subnet demonstrated below.  There are 44 host entries
corresponding to the 44 IP addresses I have control over.  Only one
host entry is needed below because all 44 look identical, except for
addresses and such.

not authoritative;
ddns-update-style none;
deny unknown-clients;
allow bootp;
use-host-decl-names on;


subnet 192.168.24.0 netmask 255.255.248.0 {
       # this server will only host bootp, thus the range is left out
       #leases
       default-lease-time 6000;
       max-lease-time 6000;
       option subnet-mask 255.255.248.0;
       option broadcast-address 192.168..31.255;
       option routers 192.168.24.1;
       option domain-name-servers 192.168.0.51;
       option domain-name "internal.domain";
}

host host1 {
       option host-name "host1";
       hardware ethernet 00:01:a2:4a:cc:af;
       fixed-address 192.168.27.0;
}


My server starts so I know I haven't any syntactic issues.
Originally, I had the "not authoritative;" line set to "authoritative"
but thought that might be it.  How should this be configured to get
this to work?  Also, I've read in the dhcpd.conf(5) manual page that
keyword "option" corresponds to actual options defined in the DHCP
spec.  Being that this is for bootp only, perhaps I can leave them
out, but I wasn't sure and have as yet left them in.

Any help is greatly appreciated thanks,
Andy
