Environment: - Windows Server 2022 - IIS 10.0 Issue Summary: I regularly collect IIS performance metrics using Windows Performance Counters. Initially, the IIS-related counter sets were all available: - Web Service - Web Service Cache - APP_POOL_WAS - WAS_W3WP - W3SVC_W3WP After a few days...

Microsoft has confirmed that October’s Patch Tuesday cumulative updates for Windows 11 — notably the October 14, 2025 packages that include KB5066835 (and earlier preview releases such as KB5065789) — have caused a regression in the Windows HTTP stack (HTTP.sys) that can break IIS-hosted sites...

A wide-ranging October 2025 cumulative update for Windows 11 (KB5066835), and at least one related preview package, has broken many local IIS-hosted sites and developer workflows — causing ERR_CONNECTION_RESET, ERR_HTTP2_PROTOCOL_ERROR and outright failure of localhost-based services for...

Ziff Davis’s engineering team and AWS partnered to replace an ad hoc, error-prone Windows server provisioning process with an automated, repeatable pipeline built on EC2 Image Builder and AWS Systems Manager — delivering consistent IIS hosts, simplified patching, and faster recovery while...

Microsoft’s September 2025 hardening update for Windows Server Update Services (WSUS) on Windows Server 2025 removes legacy update binaries used by WSUS to service the Windows Update SelfUpdate component, and that change has immediate operational implications for organizations still relying on...

Microsoft’s advisory for a newly referenced HTTP.sys vulnerability describes an out‑of‑bounds read in the Windows HTTP protocol stack that can be triggered remotely against Internet Information Services (IIS) and other HTTP.sys consumers, allowing an unauthenticated attacker to cause a...

Microsoft’s SharePoint on-premises ecosystem is once again at the center of a high-risk security incident: an untrusted-deserialization remote code execution (RCE) class of weaknesses is being actively exploited against internet-facing SharePoint Server deployments, and an exact CVE identifier...

If you need a reliable Windows Server web host on-premises or in your datacenter, installing Internet Information Services (IIS) is the obvious first step—and it’s far simpler than many administrators expect. Built into Windows Server but not enabled by default, IIS can be installed...

ESET researchers have uncovered a compact but sophisticated campaign — tracked as GhostRedirector — that has secretly turned at least 65 Internet‑facing Windows servers into a stealthy SEO‑fraud network while simultaneously installing a resilient native backdoor for long‑term access. Background...

A compact but sophisticated campaign tracked as GhostRedirector has infected at least 65 Internet‑facing Windows IIS servers and paired a stealthy native backdoor with an in‑process IIS module to run a covert, profitable SEO fraud operation that pushes third‑party gambling sites while leaving...

ESET’s researchers have uncovered a previously undocumented threat cluster that covertly poisons legitimate IIS-hosted websites to manipulate Google rankings while also planting a stealthy C++ backdoor on Windows servers — a campaign ESET calls GhostRedirector that, according to an internet-wide...

ESET researchers have uncovered a compact but sophisticated campaign — tracked as GhostRedirector — that has compromised at least 65 Internet‑facing Windows servers and combined a native C++ backdoor with a malicious IIS native module to deliver long‑lived persistence and server‑side SEO fraud...

ESET Research revealed that a previously undocumented threat actor, which the company calls GhostRedirector, compromised at least 65 Internet‑facing Windows IIS hosts and deployed two custom native components — a C++ backdoor named Rungan and a malicious IIS module called Gamshen — to run a...

ESET Research has uncovered a previously undocumented threat actor it calls GhostRedirector, which in June 2025 was found to have compromised at least 65 Windows servers across multiple countries and deployed two custom tools — a C++ backdoor named Rungan and a native IIS module named Gamshen...

Windows developers and administrators who depend on client-certificate (mTLS) workflows will need to keep using workarounds: a structural limitation introduced by TLS 1.3 and the way Windows handles TLS in kernel (http.sys / Schannel) means IIS Express on Windows 11 cannot reliably request a...

Microsoft’s Internet Information Services (IIS) and its relationship with Windows Server have resurfaced in recent reporting as a nexus of operational pain and security risk — a story that blends a high‑volume patch cycle, at least one serious authentication vulnerability, and persistent...

A recent technical feature in International Daily News highlighted some of the most overlooked yet critical components in the Microsoft ecosystem: the interaction between IIS (Internet Information Services) and the Windows Server platform, common post-installation errors in WSUS (Windows Server...

Microsoft's Internet Information Services (IIS) and its relationship with Windows Server have once again become a focus. Recent reports from Hong Kong and international media, along with practical feedback from community forums, show that as Microsoft continues to release security patches and...

IIS can appear to “refuse” a domain, WSUS post‑install can abort with 0x80070003, and small configuration mismatches in Windows Server often hide behind cryptic error messages—but the underlying causes are usually straightforward to diagnose and fix. This feature unpacks the most common IIS +...

A seemingly ordinary sports photo page titled “Falcons Cowboys Football” paired with an obituary excerpt for Odessa Dillard Foddrell, 84, who died on August 12, 2025 in Conover, North Carolina, reads like a glitch in the matrix—but it’s also a snapshot of how fragile modern, template-driven news...
