Resource Records Used by Active Directory
When you promote a domain
controller into a domain, a file containing the necessary resource
records for it to function correctly within Active Directory is
generated in
%SystemRoot%\System32\Config\netlogon.dns.
The contents of the file will look something like the following for a DC named moose.mycorp.com in the mycorp.com domain with IP address 10.1.1.1. We’ve reordered the file a bit to group records of similar purpose together. Note that some lines may wrap due to their length.
