Windows 2012 서버의 AD DS 관련

삽질한 내역.

windows 2012 AD구성시 올라가는 DNS서비스 관련 내용이며, 하위 폴더중 _msdcs.domain에 대한 폴더는 windows 2008까지는 해당도메인의 하위폴더에 생성되는것이 정상이었으나, windows 2012부터는 분리되어 root폴더에 위치함.(즉 그렇게 설치되어도 정상임)

Forest Root Zone for _msdcs

In Active Directory, all client logons and lookups are directed to local domain controllers and Global Catalog servers through references to the SRV records in DNS. These SRV records were stored in a subdomain to an Active Directory domain that is known as the _msdcs subdomain.

In Windows Server 2012, _msdcs is a separate zone in DNS, as shown in Figure 1. This zone, stored in the application partition, is replicated to every domain controller that is a DNS server. This listing of SRV records was moved mainly to satisfy the requirements of remote sites. In Windows 2000, these remote sites had to replicate the entire DNS database locally to access the _msdcs records, which led to increased replication time and reduced responsiveness. If you delegate the SRV records to their own zone, only this specific zone can be designated for replication to remote site DNS servers, saving replication throughput and increasing the response time for clients.
