subdomain question

[Tony OGER]

Tnaks Kevin,
 
I finally succeed to make my subdomain working trough my principal Domain name.
For this i added in the /etc/named.conf of the principal domain nameserver the
slave zone:

zone "run.ib-e-laser.fr" {
        type forward;
        forward only;
        forwarders { 192.168.1.203; 192.168.1.202};
};

and now it s works.
