Thanks for any help you can give

Short synopsis:

dhcpd is giving out IP addresses just fine but not completely updating the
dns, so I can't ping client_name even though dhcpd has given client_name the
IP.

Gory details:

This is RHEL ES Standard, and yes, I've contacted support and they're not
helping.  We have a non-routing "inside" class C network (192.168.197)
connected to the outside through a gateway.  That part's working great.  We
have several servers and clients.  The clients are mostly PC's.  The
client's can get their IP address, gateway, and DNS info from the dhcp
server just fine -- people surf the 'net and everything.

But I have a service on the nice server (RHEL) that requires it to
authenticate the clients.  Part of doing this is it must be able to ping the
client and lookup its IP address.  We've never had a dhcp server that could
update the local dns server so until now we manually set the IP addresses of
the clients that needed this service and kept all the /etc/hosts file up to
date.  A pain, but it worked.

I'd like to stop doing that, especially since we're growing.  I've gotten
the dhcp and dns servers both running on the RHEL server but dhcp can't
updated the dns.

Here's /etc/dhcpd.copnf with some stuff change for security (I don't know it
that's necessary but I'm being careful):

***start dhcpd.conf
ddns-update-style interim;
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;

option domain-name "somewhere.com";

key rndckey {
algorithm       hmac-md5;
secret          secret_code;
};

subnet 192.168.197.0 netmask 255.255.255.0 {
range 192.168.197.150 192.168.197.199;
}

zone SOMEWHERE.COM. {
primary 127.0.0.1;
key rndckey;
}

zone 127.0.0.in-addr.arpa. {
primary 127.0.0.1;
key rndckey;
}
***end dhcpd.conf

And here's named.conf:

***start named.conf
controls {
inet 127.0.0.1 allow { 127.0.0.1; } keys { rndckey; };
};

options {
directory "/var/named";
pid-file "/var/run/named/named.pid";
statistics-file "/var/run/named/named.stats";
dump-file "/var/run/named/named.db";
};

key "rndckey" {
algorithm  "hmac-md5";
secret   "secret_code";
};

zone  "." {
type hint;
file "db.rootcache";
};

# localhost - forward zone
zone "somewhere.com" {
type master;
notify no;
file "db.localhost";
allow-update { key rndckey; };
};

# localhost - inverse zone
zone "0.0.127.in-addr.arpa" {
type  master;
notify no;
file "db.127.0.0";
allow-update { key rndckey; };
};
***end named.conf

And here's a bit of /var/log/messages that shows the failure:
