Enable DoH (DNS over HTTPS) in Windows Server 2025 DNS server, configure Windows 11 DNS clients

Enabling dns over https in windows 11 using the cloudflare doh server
DNS over HTTPS (DoH) is a protocol that encrypts Domain Name System (DNS) queries and transmits them over HTTPS. This security enhancement prevents eavesdropping and manipulation of DNS traffic, addressing fundamental vulnerabilities in traditional DNS infrastructure that operates in plaintext. The DoH architecture consists of two components: the client, which initiates encrypted DNS queries, and the resolver (or server), which processes them. Windows has supported DoH on the client side since Windows 11. While Windows 10 includes the underlying client support in later builds (Insider Preview 19628 and later), it does not expose this functionality in the Settings app and requires manual Registry configuration, making it effectively unsupported for most users.

S2D and SAN coexistence in Windows Server failover clustering for Hyper‑V, SQL Server, and file services

Organizations running modern data centers increasingly need flexible storage architectures that balance performance, resiliency, and investment protection. With Windows Server 2022 and Windows Server 2025, Microsoft now enables true S2D and SAN coexistence—allowing Storage Spaces Direct (S2D) to operate alongside traditional SAN storage within the same failover clustering environment. This mixed-storage approach lets IT teams optimize workloads such as Hyper-V, SQL Server, and file services by combining high-performance local storage with existing enterprise SAN infrastructure, all while maintaining full cluster support and operational consistency.
