Are these two DNS server behind NAT?
If so, are you allowing zone transfers to all the private IP addresses on
the secondary DNS server's machine?
Also if they are behind the same NAT device, you *cannot* use the option
"allow zone transfers to the DNS servers list on the Name server tab" unless
these NS records are resolved to the private IP address of the NS records.
Not good if these are public DNS servers because the NS records must have
public routable addresses.
To help speed up the zone updates on the secondary, I suggest you use Notify
to notify the secondary.
