KB5062632: Overview with user sentiment and feedback

Overview

KB5062632 is a July 2025 Monthly Rollup security update for Windows Server 2008 R2 Premium Assurance. This update includes important security hardening changes to the Microsoft RPC Netlogon protocol and continues Microsoft's commitment to maintaining security for legacy systems approaching end of support. The update is particularly significant as it comes in the context of Windows Server 2008 R2 Premium Assurance's approaching end of support date in January 2026.

General Purpose

The primary purpose of this update is to implement security hardening changes to the Microsoft RPC Netlogon protocol. The update tightens access checks for remote procedure call (RPC) requests, specifically affecting how Active Directory domain controllers handle anonymous client requests through the Netlogon RPC server. After installation, domain controllers will no longer allow anonymous clients to invoke certain RPC requests typically related to domain controller location. This change may affect certain file and print service software, including Samba implementations.

General Sentiment

The general sentiment towards this update appears cautiously positive. While it implements important security hardening measures, the changes to Netlogon RPC handling could potentially impact some enterprise environments, particularly those using Samba or specific file and print services. Organizations are advised to review their current implementations, especially if they use Samba, and consult the relevant release notes before deployment. The update requires the latest Servicing Stack Update (SSU) to be installed first, which adds an extra step to the deployment process but ensures proper installation.

Known Issues

• Microsoft states they are not currently aware of any issues with this update
• The update requires installation of the latest Servicing Stack Update (KB5056456) before it can be installed
• Potential impact on file and print service software, particularly Samba implementations
• Language packs must be reinstalled if installed after this update
