About this tag
The windows server tag on WindowsForum.com covers administration, security, and troubleshooting for Microsoft's server platform. Recent discussions highlight critical August 2026 patches for Windows Server roles, including DNS Server remote code execution vulnerabilities (CVE-2026-65789, CVE-2026-62878, CVE-2026-62820), a DHCP Server information disclosure (CVE-2026-62745), and an NFS denial-of-service flaw (CVE-2026-68819). Other threads examine third-party tools and updates relevant to server environments, such as Intel XPU Manager for multi-GPU servers, Siemens License Server privilege flaws, and SolarWinds Observability Self-Hosted deployment on Windows Server 2025. The tag emphasizes practical patch management, role-specific exposure, and monitoring for enterprise IT administrators.

    Golden SAML Defense: AD FS Signing Key Risks and October 2026 DKM ACL Changes

    A forged SAML token signed with an organization's real AD FS signing key doesn't look like a break-in. To every service that trusts that identity provider, it looks like a valid credential. That's the core of Golden SAML, and it matters this week because Microsoft's hardening of the AD FS...

    Microsoft PQC TLS Pilot: Windows 11 and Server 2025 ML-DSA Certificate Testing
