1. File forward. zone and reverse.zone does not give the full privilege
2. It is configure or setting forward.zone and reverse.zone configuration file Red hat rhcl5 in Linux
IN the DNS configuration you copy the localhost.zone file to forward.zone file from /var/named/chroot/var/named/localhost.zone directory. In these step you must copy with there file with there full privilege then only DNS setting it will access the file so use option
–p

Cp –p
-p refers to the preserve mode (copy the file with same ownership and timestamp)

#cp –p /var/named/chroot/var/named/localhost.zone /var/named/chroot/var/named/forward.zone
Similarly copy the reverse.zone.
Then there second problem occur while you did not configure the Forward.Zone and reverese.zone configuration file properly.
See the configuration of DNS in Red hat RHEL5
