AVD Real-World Issue - Part 1

 In real-world IT environments, troubleshooting complex issues is a key part of ensuring seamless user experiences. Recently, we encountered a scenario where multiple users were experiencing AVD disconnections and noise across different user segments. Some users reported that during Microsoft Teams calls, they faced frequent AVD disconnections and Teams restarts.

Step 1: Identifying the Issue

To isolate the root cause, we first identified the affected users and analyzed their AVD session details. Gathering as much data as possible, we looked for common patterns among the reported cases. Through user feedback and system analysis, we found that the issue occurred in three key scenarios:

  1. RDP Shortpath Misconfiguration: RDP Shortpath was not properly configured for the AVD pool, causing suboptimal routing and unexpected disconnections.

  2. Zscaler Configuration Issues: Zscaler was not correctly configured to bypass AVD traffic, leading to session drops and unstable connectivity.

  3. CrowdStrike Exclusions: After a recent Microsoft Teams rollout, CrowdStrike did not have the necessary Teams exclusions, interfering with stable operation.

Resolution Strategy

By addressing these three core issues, we were able to significantly reduce disconnection rates and improve AVD session stability. Our next steps included implementing proper configurations for RDP Shortpath, adjusting Zscaler rules, and updating CrowdStrike policies.

Stay tuned for Part 2, where I’ll deep dive into the technical solutions we implemented to resolve these issues effectively.

How to Prevent RDP Shortpath Errors

How to Prevent RDP Shortpath Errors While RDP Shortpath enhances connectivity in Azure Virtual Desktop (AVD) and Windows 365 (W365) , you might encounter errors due to network restrictions, firewall configurations, or NAT traversal issues . Here are some key steps to prevent and troubleshoot errors: ✅ 1. Enable RDP Shortpath in Your Environment Ensure that RDP Shortpath is correctly enabled for your AVD or W365 deployment : For Managed Networks : Configure RDP Shortpath for Public Networks via Azure Portal or PowerShell. For Private Networks : Set up RDP Shortpath for Private Links using Azure Virtual Network integration. 🔗 Microsoft Documentation – RDP Shortpath Setup ✅ 2. Check Firewall & Network Settings Ensure your firewall and network policies allow UDP traffic and do not block RDP Shortpath: Allow outbound UDP traffic on port 3390 (for direct Shortpath connections). Verify inbound UDP traffic rules to allow AVD session hosts to receive direct connections. Ensu...

Mitigating Black Screen Errors with FSLogix on Windows Server 2022: Best Practices

Implementing FSLogix on Windows Server 2022 can sometimes lead to black screen issues during user logins. To minimize such occurrences, consider the following best practices: Conduct Thorough Testing: Pilot Testing: Before a full-scale deployment, select a group of 20-30 users to test the FSLogix upgrade. This helps identify potential issues in a controlled environment. Phased Rollout: Implement the upgrade in phases, starting with a small pilot group. Monitor the performance and address any issues before proceeding to a broader rollout. Ensure Proper System Reboots: After upgrading FSLogix, perform a system reboot to ensure all changes are correctly applied and to prevent potential conflicts. Collaborate with Microsoft Support: If errors are reported during the pilot phase, engage with Microsoft Support to address these issues before planning a large-scale rollout. Stay ...
