To check if named is chrooted, type:
ps -ax | grep named
If you see any mention of /var/named/chroot in the named command, then named has been chrooted.To un-chroot named back to normal, do the following:
1) move the zone files from /var/named/chroot/var/named to just /var/named
cd /var/named/chroot/var/named
mv -f * /var/named
2) move the config file and rndc.key from /var/named/chroot/etc/named.conf to just /etc/named.conf
cd /var/named/chroot/etc
mv -f named.conf /etc/named.conf
mv -f rndc.key /etc/rndc.key
3) comment out the ROOTDIR setting in /etc/sysconfig/named
4) restart named
