How to Set Up Windows Server Cluster-Aware Updating (CAU) on Windows Server 2025 Patching a Windows Server Failover Cluster without disrupting workloads has historically required careful manual coordination — draining roles, applying updates on one node, rebooting, waiting for roles to fail back, then repeating across every node. Cluster-Aware Updating (CAU) automates this entire orchestration. […]
How to Implement Just-In-Time (JIT) Administration on Windows Server 2025 Traditional privileged accounts represent one of the most significant attack surfaces in any Windows environment. When an administrator account holds permanent membership in Domain Admins or Enterprise Admins, a single compromised credential can devastate an entire forest. Just-In-Time (JIT) administration solves this by granting elevated […]
How to Configure Cross-Forest Trusts in Active Directory on Windows Server 2025 Large enterprises, mergers, and acquisition scenarios frequently require resources in one Active Directory forest to be accessible to users in a completely separate forest. Active Directory cross-forest trusts solve this by establishing a secure Kerberos referral path between forests, allowing users authenticated in […]
How to Set Up Microsoft Entra (Azure AD) Hybrid Join on Windows Server 2025 Microsoft Entra Hybrid Join — formerly known as Hybrid Azure AD Join — registers your on-premises domain-joined Windows devices in both the local Active Directory and Microsoft Entra ID simultaneously. This dual registration is the foundation for modern identity features in […]
How to Configure Multi-Site Active Directory on Windows Server 2025 As organisations grow and establish offices in multiple geographic locations, a single-site Active Directory topology becomes a bottleneck. Clients authenticate against the nearest available domain controller, replication traffic floods WAN links, and Group Policy processing slows down for remote users. Multi-site Active Directory solves these […]
How to Build Custom Windows Server Images with Packer on Windows Server 2025 Maintaining a library of consistent, pre-hardened server images dramatically reduces provisioning time and eliminates configuration drift between environments. HashiCorp Packer automates the process of building these “golden images” — fully patched, configured, and sysprepped virtual machine images that serve as the authoritative […]
How to Configure IPsec Transport Mode for Server-to-Server Encryption on Windows Server 2025 Protecting east-west traffic between servers on the same network is often overlooked, yet it is one of the most critical layers of a defence-in-depth strategy. IPsec Transport Mode encrypts only the payload of each IP packet while leaving the original IP header […]
How to Set Up a PKI Infrastructure with AD CS on Windows Server 2025 A well-designed Public Key Infrastructure (PKI) is the foundation of enterprise security — it underpins HTTPS for internal web services, mutual TLS for application authentication, smart card logon, Wi-Fi 802.1X, VPN certificate authentication, S/MIME email signing, and BitLocker key escrow. Active […]
How to Configure OpenSSH Server on Windows Server 2025 OpenSSH has been a first-class optional feature of Windows Server since 2019, and on Windows Server 2025 it receives further polish that makes it a genuinely production-ready alternative to WinRM for remote administration. SSH offers a universally understood protocol, strong key-based authentication, encrypted channel multiplexing, and […]
How to Set Up Windows Remote Management for Ansible Control on Windows Server 2025 Ansible has become the de facto standard for agentless infrastructure automation, and while it was originally built around SSH for Linux hosts, it provides first-class Windows support through WinRM (Windows Remote Management). WinRM is Microsoft’s implementation of the WS-Management protocol, and […]
