Ok.

Either none of the nameservers specified in /etc/resolv.conf is
listening or communication is blocked by a firewall setting. Maybe a
better check method is to run

dig -t ANY station22.alilou.fr @127.0.0.1

This error is due to IPv6.

Either the zone file is missing or - what I expect more - it has wrong
permissions.

chown named:named /var/named/chroot/var/named/alilou.fr.zone
chmod 644 /var/named/chroot/var/named/alilou.fr.zone

So it started.

It has to be only in 1 location. Do you run bind chrooted? Then the
first path does matter, the last is ignored/unknown to bind. Else vice
versa.

rpm -q bind-chroot
cat /etc/sysconfig/named

What is the last "zone forward.alilou.fr"? You already specified the
forward zone file for alilou.fr on top of it. "alilo.fr.zone is the
forward zone (file).

The trailing dots on the 10.194.3.39 address is wrong.

10.194.3.39 and 127.0.0.1 are the same nameserver. You gain nothing by
setting both as nameservers.
