#service named restart

Stopping named: [FAILED]
Starting named: [FAILED]

---------Edited in named.conf file---------------------

options {
listen-on port 53 { nms.example.com; 10.13.74.162; 127.0.0.1; };
directory "/var/named";
query-source port 53;
allow-query { nms.example.com; 10.13.0.0/24; };
forwarders { 10.11.8.14; };

};

zone "example.com" IN {
type master; file "example.com.zone";
allow-update { none; };
forwarders { 10.11.8.14; };
};

It looks like you are using the chroot setup but loading named.conf from /etc.
You need to modify /etc/sysconfig/named to include the following directive

ROOTDIR=/var/named/chroot

After you have modified named.conf you should always test it using

service named testconfig

The ACL (Access Control List) errors are due to the fact that you are using "nms.example.com" in the listen-on and allow-query directives in the options statement. You cannot use FQDNs this way. You must do it something like this.

acl nms {
    10.13.0.123;
};
......
listen-on port 53 { nms; 10.13.74.162; 127.0.0.1; };
......
allow-query { nms; 10.13.0.0/24; };
