Check the DNS and the ident port on the IP address this is coming from.
It's possible that the DNS is cocked up and the ident query stalls long
enough for NT to toss its cookies most of the time, and requeue the message
for another delivery attempt. But, once in a blue moon, the beast might
get distracted by something else, and by the time it finishes, you've timed
out and sent the banner.
