The only other thing I needed to fix was an incorrect DOMAINORIGIN statement, our network uses something weird. But having the wrong value *does* prevent me from pinging things.
The DNS lookup is only for fully qualified names like www.vm.ibm.com. If you give the resolver a hostname only (a single qualifier with no dots in it) the domain origin is appended to get a fully qualified name that can be looked up. An incorrect domain origin would give wrong names that cannot be looked up. Many large installations run their own DNS servers behind the firewall to let middle tiers resolve internal addresses. It's a good thing for such servers not to use external DNS because your application could be affected by tampering with that outside DNS. While it is possible to have such a DNS also resolve the address of hosts outside the firewall, some people sleep better by keeping it inside. You have to be aware what you want to resolve and which DNS to talk to. There may not be one that fits both needs. Rob
