Microsoft’s latest clarification on NTLM’s long-promised phase-out is both clearer and more cautious than many in the security community hoped: the company has laid out a phased roadmap that will push organizations away from NTLM, introduce Kerberos-first defaults and compatibility features, and...

Microsoft has begun the phased removal of RC4 from the Kerberos ticketing path in Windows Server, rolling out audit telemetry and controls in the January 13, 2026 updates and locking the timetable toward a full enforcement phase that will default to AES-only Kerberos encryption by July 2026...

Microsoft has quietly but deliberately set a firm deadline to end a decades‑long compatibility compromise: RC4 (RC4‑HMAC) will no longer be the assumed, permissive fallback for Kerberos ticket encryption on Windows domain controllers, and Microsoft has delivered a staged rollout tied to...

Upgrading domain controllers to Windows Server 2025 is a major milestone, but the work doesn’t end at promotion and replication. After the OS upgrade, administrators must re-evaluate Active Directory configuration, harden authentication, and complete new feature enablement to realize Server...

A new trainee-level IT role at Tilbury Ports — advertised through Thurrock Nub News and staffed by Forth Ports — offers a hands-on entry into enterprise IT support with a clear Microsoft-centric focus and real-world exposure to hybrid infrastructure, endpoint management, and port‑scale...

Microsoft has set a firm deadline to end a decades‑long compatibility compromise: by mid‑2026 domain controllers running Windows Server 2008 and later will default to issuing AES‑SHA1 Kerberos session keys and RC4 will be disabled by default, forcing organizations to find and remediate remaining...

Microsoft’s plan to end RC4 as a Kerberos default marks a clear, overdue break with a decades‑old compatibility choice that has long weakened Active Directory security; by mid‑2026 domain controllers running Windows Server 2008 and later will default to issuing AES‑SHA1 session keys for Kerberos...

Microsoft’s decision to flip a long-standing encryption default in Active Directory — moving Kerberos away from RC4 and toward AES-SHA1 by default — is the most consequential security change for Windows authentication in years, and it arrives after more than two decades of compatibility-first...

Microsoft’s decision to phase out the RC4 cipher from Active Directory authentication marks a decisive response to decades of risky backward compatibility — but it also forces a hard reckoning for enterprises that have long depended on legacy interoperability over cryptographic hygiene...

Microsoft is moving Windows authentication firmly away from the legacy RC4 cipher and adding concrete detection and remediation tooling so administrators can identify, isolate, and remediate RC4-dependent accounts and devices before the change becomes the default behavior in domain environments...

Cayosoft’s new Guardian Protector brings always-on identity monitoring to teams that still treat Active Directory and Entra ID as the single most critical risk vector, promising real-time alerts, agentless deployment, and a freemium model that removes cost as the first barrier to better hybrid...

Terraform can provision an Azure Windows VM and, with a single VM extension call, make that VM an Active Directory member so it’s ready for work the moment provisioning finishes — but doing this safely and reliably at scale requires careful choices about secrets, identities, network design and...

Upgrading Active Directory domain controllers to Windows Server 2025 is achievable for most organizations, but it demands a disciplined migration plan, careful testing, and attention to a few high‑risk failure modes that can break replication or block forestwide features if overlooked...

Microsoft’s September/October servicing cycle has produced a high-impact collision between a Windows Server 2025 cumulative update and enterprise identity tooling, leaving some organizations with partial directory synchronization and dangerous AD replication failures — a problem Microsoft now...

Microsoft has confirmed that a September 2025 cumulative update for Windows Server 2025 (KB5065426) introduced an Active Directory (AD) replication defect that can break directory synchronization in mixed-version forests when the forest Schema Master FSMO role is hosted on a Windows Server 2025...

Microsoft’s security update for September (KB5065426) has been implicated in a rising wave of identity and file‑sharing headaches for organizations that have adopted Windows Server 2025—yet the most alarming claim now circulating, that a DirSync/Entra Connect group‑sync bug in KB5065426 silently...

Microsoft has confirmed a Windows Server bug that can break Active Directory schema replication when the forest Schema Master FSMO role is hosted on a Windows Server 2025 domain controller and an Exchange schema change is applied, producing schema‑mismatch replication errors that can rapidly...

A subtle but dangerous defect in Windows Server 2025’s schema-master behavior is now a confirmed production risk: when the forest Schema Master FSMO role is hosted on a Windows Server 2025 domain controller and an Exchange on‑premises schema extension (for example, Exchange Server 2019 CU15 or...

Microsoft has confirmed a high-impact Active Directory (AD) replication defect that can break domain controller synchronization when the forest Schema Master FSMO role is hosted on a Windows Server 2025 domain controller and Exchange schema changes are applied — a narrow trigger that nonetheless...

Microsoft and Exchange teams are warning administrators about a narrow—but potentially high‑impact—Active Directory schema replication problem that can surface when an Exchange cumulative update (for example, Exchange 2019 CU15 or Exchange Server Subscription Edition RTM) extends the schema...
