RIS - Streaming Initialization Failure After Recent Windows Updates

Question

We are experiencing an issue on multiple radiology workstations following the installation of recent Windows updates.

Users can successfully authenticate to GE Centricity; however, the application fails during the streaming initialization phase. As a result, radiologists are unable to view recent studies, including Emergency Department (ER) cases.

Observed behavior:

• Authentication completes successfully.
• Streaming initialization fails after login.
• Recent and active studies are not displayed.
• Issue reported across multiple workstations.

Environment:

• Windows 11 systems with KB5094126 installed.
• Windows 10 systems with KB5094123 and/or KB5094127 installed.

The RIS team has observed similar behavior at multiple healthcare sites and indicated that removing the above updates may temporarily restore functionality.

Please investigate whether these updates introduce changes affecting:

• TLS/SSL communication
• Certificate validation
• Enterprise application streaming
• Network security policies
• Compatibility with healthcare applications such as GE Centricity

Any guidance regarding known issues, mitigation steps, or compatibility concerns would be appreciated.We are experiencing an issue on multiple radiology workstations following the installation of recent Windows updates.

Answer 1

Hello T10D, thank you for posting in the Microsoft Q&A community.

When aN application authenticates successfully but fails to initialize data streaming post-update, it generally points to security payloads introduced in recent cumulative updates. The most common technical reasons include stricter validation for DCOM/RPC connections that legacy applications may not natively support, or modifications to Schannel (Secure Channel) enforcing strict TLS cipher suites that might block the streaming port.

Since removing the updates temporarily restores functionality, the most effective standard resolution is to temporarily pause these updates while isolating the root cause. You can leverage Group Policy or Microsoft Intune to pause Quality Updates for the affected radiology workstation Organizational Units. Additionally, I recommend engaging GE Healthcare support alongside our troubleshooting, as enterprise medical applications frequently require specific vendor-provided configuration patches to comply with new Windows security baselines.

To help us pinpoint the exact change causing this streaming failure, I need to review some diagnostic data from a machine where the update is currently installed. Could you please open Event Viewer and navigate to Windows Logs > System to look for any Schannel errors (such as Event ID 36871 or 36874) or DCOM errors (such as Event ID 10036)? Also, please check Windows Logs > Application for specific .NET or application crashes during the exact time the streaming fails.

Answer 2

The provided context does not contain any information about KB5094126, KB5094123, or KB5094127, nor any documented issues specifically affecting GE Centricity, RIS/PACS streaming, or recent TLS/SSL or certificate-validation changes tied to those KBs.

No known issues, mitigations, or compatibility notes related to those specific updates can be confirmed from the available documentation.
