Zone Delegation

[Holger Honert]

Hello there,
 
I have the zone a-ds.de which master is running on AIX 4.3.3 Server BIND
V8.2.4
I want to delegate a zone fd.a-ds.de to 2 W2k Servers so I added in the
zone 
Data 
 
@        86400   IN      SOA     ns-koms.a-ds.de. honert.signal.de. (
                2002031315 10800 3600 604800 86400 )    
        86400   IN      NS      ns-koms.a-ds.de.        
 
ns-koms 86400   IN      A       172.16.100.125  
 
fd      86400   IN      NS      fddc51.fd.a-ds.de.      
        86400   IN      NS      fddc52.fd.a-ds.de.      
fddc52.fd.a-ds.de.  86400   IN      A       10.48.0.4       
fddc51.fd.a-ds.de.  86400   IN      A       10.48.0.2       
 
My question now is why is it not possible to query from my master better
said from
all Clients in a-ds.de configured ns-koms.a-ds.de as their prim. NS,
hosts from the delegated 
Domain fd.a-ds.de. 
 
What have I made wrong if so ??
 
Thx in advance
