Windows Server is getting new network safety capabilities with DNS over HTTPS

Microsoft has introduced DNS over HTTPS (DoH) on Windows Server 2025, enhancing network security by encrypting DNS traffic for client-to-server communications. This feature, previously available only in Windows client editions, is now part of Microsoft's Zero Trust architecture. DoH routes DNS traffic through HTTPS secured with TLS certificates, preventing eavesdropping and safeguarding DNS data from tampering. It adheres to the IETF DNS over HTTPS standard (RFC 8484) and can integrate with existing infrastructure, allowing organizations to maintain unencrypted DNS traffic if needed. DoH is available for Windows Server 2025 systems updated to the latest Patch Tuesday release, and Microsoft has provided guidance on enabling this feature. However, DNS traffic exchanged between two DNS servers will not be encrypted by DoH.

Windows Server 2025 Adds DNS Over HTTPS for Secure DNS Traffic

Microsoft has rolled out support for DNS over HTTPS (DoH) in Windows DNS Server as part of the Windows Server 2025 update. This feature enhances the security of DNS communications through encryption and server authentication, allowing encrypted client-to-resolver traffic in on-premises DNS environments. DoH encrypts DNS queries and responses using HTTPS, protecting sensitive information from interception or alteration. It also uses digital certificates for DNS server authentication to reduce spoofing and impersonation risks. The feature is compatible with existing Windows DNS Server configurations and supports both encrypted and traditional DNS. DoH support is available on Windows Server 2025 with the June 9, 2026 update or newer. Administrators must configure a trusted TLS certificate and enable DoH in the DNS Server service to deploy this feature. Microsoft plans to extend encryption capabilities to include communication between the Windows DNS Server and upstream DNS resolvers in the future.
