Reverse Lookup Question

[Gawie Marais]

i have two name servers on my network. forward requests work as well as 
reverse lookup requests. i have been assigned part of a network class 
from my service provider. however, when i register a new .co.za domain, 
which is correctly setup on my systems, i get the following error 
message back.

maybe this means something to someone out there that could explain to me 
what is happening here ::
