Thanks for your answer. There are no other records with that name in the
zone, and an ANY query comes back empty but still with status of
NOERROR. Unfortunately, I can't provide the query and zone data, and I
do understand that prevents you from helping.

I was hoping someone else had come across this at some point.

Thanks again,
