Hi Sorry I made a mistake in the first email The entries in the named.conf is as follows zone "asti.ac.za" { type slave; file "secondary/asti/asti.ac.za"; masters { 137.158.128.1; }; check-names warn; allow-update { none; }; allow-transfer { any; }; allow-query { any; }; }; Sorry about that Thanks Cheers sherona
