while checking my hosts i found that they are unreachable, I checked the named and i got this error:
ndc: error: isc/ctl_clnt::conn_done: evConnect: Transport endpoint is not connected

Are your hosts unreachable by ip address as well as domain name?

they are reachable by ip but NOT by hostname

Was it working before? I would try stripping down your named.conf and zone files to just basics and testing just a little at a time.

By the way, if you are trying to test your DNS from your DNS server you need to specify that you are using that server and not the ones in it's /etc/resolv.conf (i.e. if your server is 192.168.1.1 then do:
host myothermachine 192.168.1.1
from that machine)

Check /var/log/messages for an ndc error your bind might have crashed and not cleaned up the socket properly. If that's the case try /etc/init.d/named restart and see if it will start up again.

If it does successfully start up go back to /var/log/messages and see if it crashes again and you might be able to see why and fix it.
