The NW51 Server is used as a DNS Server.

The name resolution works fine from clients on our LAN, but doesn't work
at all from the NW51 server itself.

I check numerous TID on that problem, but my configuration seems correct.

resolv.cfg is configured like this :

domain equad.fr

I'm unable to ping any local or external address from the NW51 server,
with the famous message "make sure netdb.nlm is loaded and resolv.cfg
configured correctly"

The only solution I found at this moment is to add some addresses in the
HOSTS file, but it can't be a long-term solution.

Have you any clue ?
