DNS client settings in Windows 2000 Server and in Windows Server 2003

 

Hace algunos días, me preguntaban como configurar los DNS primario y secundario de los controladores de dominio, pues bien aquí dejo las opciones que tenemos al realizar esta configuración:

Configure the Preferred DNS server in TCP/IP properties on each Domain Controller to use itself as Primary DNS Server.

• Advantages:
  Ensures that DNS queries originating from the Domain Controller will be resolved locally if possible. Will minimize impact of Domain Controller’s DNS queries on the network
• Disadvantages:
  Dependant on Active Directory replication to ensure that DNS zone is up to date. Lengthy replication failures may result in an incomplete set of entries in the zone.

Configure all Domain Controllers to use a centralized DNS server as their Preferred DNS Server.

• Advantages:
  • Minimizes the reliance on Active Directory replication for DNS zone updates of Domain Controller locator records. This includes faster discovery of new or updated Domain Controller locator records, as replication lag time is not an issue.
  • Provides a single authoritative DNS server, which may be useful when troubleshooting Active Directory replication issues
• Disadvantages:
  • Will more heavily utilize the network to resolve DNS queries originating from the Domain Controller
  • DNS name resolution may be dependant on network stability; loss of connectivity to the Preferred DNS server will result in failure to resolve DNS queries from the Domain Controller. This may result in apparent loss of connectivity, even to locations that are not across the lost network segment.
