child domians dif ip

Just a little confused as how to set up a child domian on a seperate ip
address. Example I have the domian computerking.ca with a name server
running on it this machine resides at ip 68.xx.xx.xx. Now i have setup
another machine accross town and want it to be
shoemasters.computerking.ca it also has bind running and is all setup to
be shoemasters.computerking.ca but for some reason it is not working.
What am i missing is it a record somewhere or is it in my named.conf
file have included my conf files please help.

Server: ns1.kloth.net Address: 213.133.98.149#53 ** server can't find
shoemasters.computerking.ca.: NXDOMAIN

I have set up my named.conf files like this on the
shoemasters.computerking.ca machine

view "external" {
match-clients { any; };
recursion no;

zone "shoemasters.computerking.ca" {
type master;
file "pz/db.shoemasters.computerking.ca.external";
};

zone "231.144.68.in-addr.arpa" {
type master;
file "pz/db.68.144.231";
};

zone "computerking.ca" {
type slave;
file "sz/db.computerking.ca.external";
masters { 68.146.233.221; };
};

zone "233.146.68.in-addr.arpa" {
type slave;
file "sz/db.68.146.233";
masters { 68.146.233.221; };
};

zone "highcoup.ca" {
type slave;
file "sz/db.higcoup.ca.external";
masters { 198.53.146.238; };
};

zone "146.53.198.in-addr.arpa" {
type slave;
file "sz/db.higcoup.ca.external";
masters { 198.53.146.238; };
};

zone "146.53.198.in-addr.arpa" {
type slave;
file "sz/db.198.53.146";
masters { 198.53.146.238; };
};

zone "." in {
type hint;
file "db.cache";
};

};
//================================================== ===========================
// end of file

This is the comptuterking.ca machines named.conf

view "external" {
match-clients { any; };
recursion no;

zone "computerking.ca" {
type master;
file "pz/db.computerking.ca.external";
};

zone "233.146.68.in-addr.arpa" {
type master;

type slave;
file "sz/db.higcoup.ca.external";
masters { 198.53.146.238; };
};
