Case Study: Europe Large Financial Company achieves centralized AD-integrated DNS and high availability with Happiest Minds

DNS Migration for a Large Financial Company in Europe

Happiest Minds worked with a large financial company in Europe to standardize and modernize its DNS infrastructure. The client required migration to Microsoft AD–integrated DNS, continuous status and functional checks to avoid disruption to productivity applications, and well-documented, controlled change processes to minimize business and user impact.

Happiest Minds executed a planned migration of zones and sub‑zones, configured Novell eDirectory and DNS to forward queries to the central infrastructure, and updated DHCP servers to manage client DNS records. The project delivered a single, centrally managed DNS platform with a unified view of zones, Active Directory replication for high availability and backup, and a lint‑collection cleanup process that removed unused records for a sanitized environment.
