no-cache dns server error

[Tom Ral]

I am running into some problems trying to setup a chrooted,
authoritative-only, no-caching DNS server using bind-9.2.3.  I keep
getting message "server can't find <server_name>: REFUSED" when I
tried nslookup.  localhost resolves fine, however.  I hope someone out
here would know what I am missing in my DNS configuration.  The
configuration files for my dns server are as follows:

=== named.conf

options {
        directory "/var/bind";
        pid-file "/var/run/named.pid";
        version "[SECURED]";
        allow-transfer { none; };
        notify no;
	auth-nxdomain yes;
# Disable cache
	recursion no;
	additional-from-auth no;
	additional-from-cache no;
};

zone "localhost" {
               type master;
               file "localhost";
};
                
zone "0.0.127.in-addr.arpa" in {
               type master;
               file "127.0.0";
             };
zone "lecomp" {
                type master;
                file "lecomp";
                };      

zone "100.168.192.in-appr-arpa" {
                type master;
                file "192.168.100";
		};
