SO I apparently have a big problem. We run a parent-child domain structure here. And today I noticed that I was having replication failures between the DCs in the root domain and some of the DCs in the child domain.
I do dnslint on the DC in the child domain, all is fine. I do dnslint on the DC in the root domain, and I get errors. Specifically, missing glue records for all 6 DCs in the child domain. I don't know how they could have disappeared. I know we demoted a DC in the child domain a couple weeks ago, but that was a graceful demotion, and showed no errors. Nothing was done in the root domain (we actually haven't done anything manual to it in years). But something screwed up royally, obviously. And I'm not sure where to go here. I get that I need to create A records in my DNS (dunno how they disappeared), but I don't know how to do that, since they are for the DCs in the child domain. And this has to be done at the root domain level, unless I am totally mis-understanding. Any help greatly appreciated. Apparently replication has been screwed up for 12 or 13 days now.
