Is this the call to finddcs_cldap() called from
the python glue in:

source4/libnet/py_net.c

? If so, adding 3x retries there would be fairly
simple.

Just wanted to thank you for the debugging work
here ! I tried but just couldn't reproduce this,
and thinking of adding a 2 second sleep in
dns_transaction_udp() to reproduce a slow server
was a great insight (obvious in hindsight, but
all the great insights usually are. i.e. I hate
myself for being too dumb to spot this :-). !

Jeremy.
