more primary DNS servers. Thers no problem using it with BIND primary
server. However AXFR transfer from primary Windows Server 200(3|8) DNS
servers include poison A entry like:

; NSD version 2.3.7
; zone 'domain.tld.'   first transfer
; from using AXFR at Fri Nov 12 17:18:53 2010
; NOT TSIG verified
$ORIGIN tld.
domain        3600    IN      SOA     ns.windows.tld.
hostmaster.domain.tld. ( 73 900 600 86400 3600 )
        3600    IN      NS      ns.windows.tld.
        3600    IN      NS      ns2.nsd.tld.


$ORIGIN windows.tld.
ns      3600    IN      A
$ORIGIN nsd.tld.
ns2     3600    IN      A
$ORIGIN domain.tld.

That A entry in transfered data cause compile error in zonec.
Both (zonec and nsd-xfer) are called by nsdc.

Is there any solution to discard this poison entry on transfer?

Best Regards!
