🚨 Critical DHCP Issues After June 2025 Patch Tuesday – What You Need to Know 🚨

Submitted by Justin Swank on

Heads up for IT teams: Microsoft has officially acknowledged issues with DHCP Server services following the latest June 2025 cumulative updates for Windows Server.

🖥️ Affected Versions:

  • Windows Server 2016 (KB5061010)

  • Windows Server 2019 (KB5060531)

  • Windows Server 2022 (KB5060526)

  • Windows Server 2025 (KB5060842)

💥 The Issue
Post-installation, some DHCP Servers may become unresponsive or stop accepting connections, leading to client IP renewal failures. This can cause intermittent network outages in dynamic IP environments.

🛠️ What You Should Do:

  • Review DHCP logs for anomalies or lease failures

  • Postpone deployment of these updates on critical DHCP servers

  • Follow Microsoft’s status page for ongoing investigations and future fixes

✅ Already a HealthNet Member-Site? You’re Covered.
The affected patches have already been removed from patch payloads deployed to HealthNet Member-Sites, so there’s no action needed on your end. 🛡️

Just one of the many ways we keep HealthNet Member-Sites a step ahead. 😉

We'll keep monitoring and post updates as Microsoft releases a workaround or hotfix.
