Hi, Paul,

To be honest, I don't know too much about this myself, but

I would suggest going into DNS Manager. If you right-click on any primary
zone you have there, and select the Notify tab, you will see if that zone is
trying to send information somewhere.

If you comb your zones (examine all of the records for each zone) you may
find that some zone is for some reason trying to send information to itself.

I'm not sure if that's the problem, but the "fine-toothed comb" approach has
worked for me in the past.

Good luck,
Adam
