Recently migrated our domain to 2016 AD from 2012 R2. Promoted the new DC’s, Demoted
the old and everything
Ran some dcdiag and repadmin commands and everything comes back clean. Verified all
the DC’s are replicating.
The only issue is that the last DC I demoted is still showing in AD Sites and Services with a file
named MSdns-serversettings showing underneath it. I’ve deleted old DC’s from S&S before,
but I cant remember seeing this file before. Is it safe to delete?
