Diagnose the Domain Name System mechanisms that Active Directory Domain Services requires for service discovery, site-aware domain controller selection, secure registration, and replication.
Learning objectives
By the end of this module, you can:
- Explain how Active Directory Domain Services uses Domain Name System for service discovery and replication prerequisites.
- Trace domain controller location through service records, Lightweight Directory Access Protocol User Datagram Protocol ping, site selection, and caching.
- Interpret the zones and resource records that domain controllers register and consume.
- Explain directory-integrated zones, application directory partitions, secure dynamic update, and replication convergence.
- Evaluate client, server, zone, delegation, registration, and site configuration against a known-good baseline.
- Diagnose and verify recovery from a Domain Name System-related directory service failure.
Prerequisites
- Knowledge of Domain Name System namespaces, zones, delegations, recursion, forwarding, caching, and common record types.
- Knowledge of Active Directory Domain Services forests, domains, domain controllers, sites, subnets, replication, global catalogs, and operations master roles.
- Experience with Internet Protocol configuration, firewalls, Windows Server administration, PowerShell, Event Viewer, Domain Name System Manager, and directory service administration tools.
