I made a domain with 2 DCs one is off and I get "spamed" by the other DCs with those message.
I think that in case that the server is not reachable this should not be emitted (or not by default). And even if the server is accessible (pingable) the frequency of this message should be less frequent.
I guess this has been fixed since a couple of month. It can be closed
Thanks for the info, ekacnet, marking it as "FIXED".
