SCOM 2022 UR3 Hotfix (KB5071859): What’s Fixed, Why It Matters, and How to Check

by

Introduction

Microsoft has released a targeted hotfix for System Center Operations Manager (SCOM) 2022 Update Rollup 3 (UR3). It addresses important compliance, security, and reliability issues seen after UR3. If your environment is on SCOM 2022 UR3, this update is highly recommended.

What’s Fixed

1) GB18030‑2022 Amendment Compliance

The hotfix ensures full conformance with China’s GB18030‑2022 Amendment across multiple UI and reporting areas in SCOM. Before this fix, certain GB18030 characters wouldn’t render correctly in:

  • Reports
  • Dashboard creation input fields
  • Active Alerts page (right task panel)
  • Alert view title
    This update addresses those display gaps, meeting mandated encoding standards for multilingual environments.

2) UNIX/Linux Monitoring: SCX Agent Certificate Signing Restored

Cross‑platform monitoring reliability gets a boost: the hotfix restores the functionality of scxcertconfig.exe so you can sign certificates and proceed with SCX agent installation on UNIX/Linux systems without the prior failure modes.

3) Security Hardening: PowerShell Widget Access Restricted to Admins

Previously, non‑admin users could access PowerShell widgets on dashboards via the web console—a risk in tightly controlled environments. The hotfix limits editing of PowerShell widgets to Administrators, aligning with least‑privilege practices and reducing exposure through dashboard scripting.

4) Agent Discovery Wizard: Missing C$ Share Error Resolved

Environments encountering the wizard error—

“The Operations Manager Server could not find directory \\SERVERNAME\C$\WINDOWS. Agent will not be installed on computer SERVERNAME.domain.com. Please verify the required share exists.”
—should see this discovery/agent installation issue resolved post‑hotfix.

5) Web Console Views Issue Fixed

“Windows Service State” and “Process State” views that failed to load after UR3 now work as expected, restoring visibility for operators relying on these core web console views.

Why This Hotfix Matters

  • Regulatory compliance (GB18030): If you operate in China or serve Chinese customers, accurate multilingual rendering in reports and UIs is essential. This hotfix aligns SCOM with GB18030‑2022 requirements.
  • Cross‑platform reliability: Restored SCX certificate signing removes blockers in UNIX/Linux agent onboarding and stabilizes cross‑platform monitoring.
  • Security posture: Restricting PowerShell widget editing to admins closes an unnecessary pathway for script exposure in dashboards.
  • Operator productivity: Fixes to critical web console views and the Agent Discovery Wizard remove friction, speeding up day‑to‑day operations.

Quick Checks to Confirm You’re Good

  • Character rendering: Validate GB18030 characters in a sample report, in dashboard input fields, and on the Active Alerts task panel and alert view title.
  • UNIX/Linux onboarding: Run a test discovery on a UNIX/Linux node to confirm certificate signing and agent install flow is healthy.
  • Security behavior: Attempt to edit a PowerShell widget as a non‑admin user (should be blocked).
  • Web console views: Open Windows Service State and Process State views and confirm they load without error.
