Ever since patching a few servers to Netware 6.5 SP6, we have been seeing
these particular servers stop DNS name resolution. My first indication is
when they fall out of timesync (we use a DNS name for our time server) and
then when I try to ping any DNS name from the server console thereafter it
returns the following:

Could not understand "www.whatever" as a host name or address. Please make
sure NETDB.NLM is loaded and sys:\etc\resolv.cfg is configured correctly.

It is only occuring on Netware 6.5 SP6 servers.
