More followup. I've now installed wireshark to see what is actually
happening on the wire.

1. When trying to ping a host with its FQDN, nothing appears on the wire
-- I was expecting to see a DNS query.

2. The DNS client service was set to automatic startup and running, as
expected. Stopping and starting the service had no effect.

3. As a quick test, I enabled NetBIOS over TCP/IP. Pinging the host did
produce three NBMS name query packets.

So where do I go from here to persuade the DNS client to do something
useful?
