I found Alan's issue and wanted to pass it along in case it helps anyone 
in the future.

The server had an entry in the reverse DNS (aka "network" dropdown in 
the "Edit Primary Services" screen) for the 0.0.0.127.in-addr.arpa zone. 
    I'm not sure why that popped up in there, but I believe it may have 
done so after importing from the old server.   The problem is that BIND 
(or "named") chokes on that and then fails to start.  So nameservice was 
never really running.

The solution is to "Remove Records" so that the zone gets wiped out, 
BIND is restarted, and the problem is solved.

I didn't happen to have shell access to the system this go-round, but 
when I've seen this behavior before it's pretty easy to restart BIND 
from the CLI (service named restart) and if it fails it's pretty good 
about reporting why.   That can greatly speed TTR (Time To Resolution)!
