I`m scratching my head on an issue here.
We had a DC that had issues replicating the domain and we had to demote and promote it back to get the replication to work.
dcpromo went fine during the demote, metadata cleanup showed nothing related to the old server. All good. Dcpromo it back, not a single issue, replication works as intended and everything is as it should be, except for one thing. It is not updating the msdcs zone in DNS for service roles.
When running nltest /dsregdns the command passes and says success, however nothing gets updated. dcdiag /fix does nothing, repadmin shows all replication works.
I can add manually the records and do a dcdiag and everything comes up fine, however I would like to understand why the records didnt get created automatically. We had brought up another DC a month ago and that one registered in 30...
