Azure Virtual Desktop Mil Email Sign-in
I am on a macbook, my windows app is downloaded and working, I entered a workspace URL that I found online that should work for mil emails, but it wont let me sign in. Yes, I completed the AVD sign up process was able to access my mil email on my windows PC, but now I am atempting to access it on my mac laptop. I'm not sure what to do. the URL that I found on the internet to enter was "rdweb.wvd.azure.us." Attached is a picture of what I see when I sign into my mil email on the AVD.
Windows 11 24H2 Multi User Marketplace Image - Sysprem Issue
We are experiencing an issue with our deployment process this month which ties in with Microsoft's October release of the new Windows 11 24H2 Multi-User Marketplace Image. The issue occurs during the sysprep of the image in our management tool Nerdio before putting it in the Azure compute gallery for use when provisioning new hosts. Our process hasn’t changed and is completely automated. Sometime around 15 th October the process started erroring on the sysprep stage, this was also the point we noticed the new Microsoft marketplace image had dropped in Azure. The process times out in Nerdio when it is running through the automated process, looking at the logs sysprep is complaining about bitlocker been turned on. If we change the image to a single user version of 24H2 gen 2 it works as does using the September version of the Windows 11 24H2 Multi-User Image. Marketplace Image: SKU - win11-24h2-avd / Version- 26100.9711.261011 PublisherName - MicrosoftWindowsDesktop Management Tooling Nerdio Manager for Enterprise v8.2.2 Thanks in advance.
GPO's not applying at startup for users
I have an environment with a Windows 10 AVD. When users sign into this environment there are no issues. I have created a new VM with Windows 11 AVD. Both Win 10 and Win 11 are domain joined. On the Win 10 the GPO's pushed have no issues but on the Win 11 AVD the GPO's are not populating. Running gpresult /r has this output: Running gpupdate /force then brings up the GPO's. So my frustration is I do not understand why the GPO's do not apply to user on sign in to their Win 11 instance. Anyone have any idea?
Windows App iOS RemoteApp Won't Reconnect
We are building a RemoteApp environment using AVD for the session hosts. On iOS, what happens is the screen powers off/device goes to sleep. When a user logs back into the iPad, the RemoteApp was still the focus, so they see buttons to reconnect or disconnect. If we press reconnect, it will either spin endlessly OR it will report an error on reconnection attempt. If we then close the error OR if we press disconnect where it drops us into the Windows App, then reopen the exact same Windows App it immediately reconnects. This does not happen in Windows at all, we have no Android deployments to test, and are trying iOS deployments on iPad and troubleshooting with iPhones. Both device types experience the issue. To troubleshoot, I've tried multiple iOS devices by multiple users; same problem. Those same users connecting to our AVD desktops, not RemoteApps, reconnect without issue. Our AVD and RemoteApp session hosts all use the same Group Policies and are, at this point, only domain joined, not Entra or Hybrid. Any thoughts on why this happens? Would logs be helpful?Problems with FSLogix 3.26 - W11 MU - 10 users per Vm
Scenario Overview We are documenting a recurring intermittent Denial of Service (DoS) regarding user profiles in an AVD multi-session environment using Azure Files Premium (SMB). The issue consistently surfaces after updating to the FSLogix 3.26 branch (v3.26.126.19110). Root Cause Analysis (Failure Logs) Through deep log analysis, we identified a "driver poisoning" pattern unique to version 3.26: SMB/Kerberos Handshake Sensitivity: Under varying storage response times (latency spikes of ~350ms vs. the usual ~40ms), version 3.26 triggers an intermittent 1326 error (Logon failure: unknown user name or bad password). Driver Execution Flow Corruption: Unlike previous versions, after this initial network/authentication glitch, the 3.26 driver fails to release execution threads or volume handles properly. Catastrophic Failure (Error 267): The system attempts to access the SecuredProfileRegData path within the mounted VHDX, but the driver returns Event ID 26: "0x10b - The directory name is invalid". Unrecoverable "Zombie" State: Once Error 267 occurs, the VM becomes "poisoned." It blocks all subsequent login attempts and even prevents a clean uninstallation of the agent (MSI Error 0x80070643 due to files being "in use"), necessitating a full VM reboot or redeployment. Has anyone else been through this? My first step was to go back to Agent Version 2506 (2210 Hotfix 4) Evidence of Success with Version 2506 (2210 Hotfix 4) After performing a clean deployment and reverting to version 3.25.626.21064, metrics from April 24, 2026, show absolute stability on the same infrastructure: Consistent Logon Times: Average profile load time of 1.6 seconds across multiple concurrent users Storage Efficiency: FindFile response times remained stable between 39ms and 45ms, with the agent successfully retrying any momentary delays. Error Resilience: Unlike v3.26, if this version encounters an authentication glitch (e.g., on a local service account), it bypasses the error and remains functional, allowing domain users to log in without collateral blockages. Concurrency Support: Seamlessly managed over 20 simultaneously mounted volumes without pointer collisions or kernel hangs.Dynamic hostpool sessions not updating
We have created a dynamic host pool in a test environment. We see that new hosts are being created based on the scaling plan. However, these are no longer being deleted. When we look at the status, we see that there are no active sessions, but when we zoom in on the session hosts, it shows that there is a session on two of the three hosts. The latter is incorrect, but it is likely the reason why scaling down is not taking place. Does anyone recognize this? Is there possibly a solution for this? Small addition: If I log in with a user and then log out properly, the current sessions in the host pool overview are updated quickly. However, if I then go to Manage, Session Hosts, the total sessions on that host remain at 1. When I now put the host in drinamode, only then are the actual sessions updated.Uninstalling Remote Desktop client closes users' Windows App connections
We have our users working from Windows App now to meet the 3/27 out of support date. We are beginning to uninstall the Remote Desktop from their laptops and are finding it closes active Windows App connections on uninstall (of Remote Desktop). That is less than ideal. Looking to see if any way around that, but wondered if others had seen the same?WindowsAppRuntime 1.4 Failures in AVD Multi-Session – Event ID 404 Production Case
We recently experienced a production issue in an Azure Virtual Desktop multi-session environment that initially looked random — but turned out to be a shared framework instability amplified by scale. Environment: AVD multi-session host pools FSLogix profile containers MSIX App Attach Intune-managed Clean golden image Everything looked healthy. Yet packaged applications started failing across multiple host pools. Symptoms observed Users reported: Error 0x80070005 AppXDeploymentServer Event ID 404 WindowsAppRuntime 1.4 marked as NeedsRemediation Failures persisted after: Reboots Host redeployments Image rebuild This was not: A profile corruption issue An App Attach packaging issue An Intune deployment failure What actually broke Under session churn conditions (logoff / new session / runtime re-validation), WindowsAppRuntime 1.4 entered a NeedsRemediation state. Event Viewer showed: AppXDeploymentServer Event ID 404 HRESULT 0x80070005 Runtime file creation failure under WindowsApps Multi-session did not cause the issue. It amplified it. Shared framework registration timing under concurrent sessions made a rare condition systemic. Why multi-session exposed it In single-session environments, runtime inconsistencies remain isolated. In multi-session: Shared framework dependencies are reused Concurrent validation occurs Host pools recycle under load Registration timing becomes critical What would be a rare edge case became recurring instability. Remediation approach Instead of periodic polling, we moved to event-driven self-healing. Detection trigger: AppXDeploymentServer Event ID 404 Remediation logic: Restart AppXSVC Re-provision WindowsAppRuntime 1.4 Prevent concurrent duplicate execution Log execution We implemented a Scheduled Task: Monitoring Operational log Triggering immediately on Event ID 404 Running under SYSTEM Deployed via Intune Win32 package Detection logic validating task presence This converted reactive troubleshooting into automated correction across host pools. Architectural takeaway Multi-session environments amplify shared dependency weaknesses. WindowsAppRuntime is not “just another component” — it is a platform dependency. If the runtime layer drifts, everything layered above it collapses: MSIX App Attach Packaged apps Registration consistency Self-healing must be part of AVD design. For the structured technical case study (including deployment pattern and remediation logic), full write-up here: https://modernendpoint.tech/avd-multi-session-failure-analysis/ Has anyone else observed WindowsAppRuntime 1.4 entering a NeedsRemediation state under multi-session load? Curious if others saw correlation with specific Windows updates. — Menahem Suissa Modern Endpoint ArchitectImproper AVD Host Decommissioning – A Practical Governance Framework
Hi everyone, After working with multiple production Azure Virtual Desktop environments, I noticed a recurring issue that rarely gets documented properly: Improper host decommissioning. Scaling out AVD is easy. Scaling down safely is where environments silently drift. Common issues I’ve seen in the field: Session hosts deleted before drain completion Orphaned Entra ID device objects Intune-managed device records left behind Stale registration tokens FSLogix containers remaining locked Defender onboarding objects not cleaned Host pool inconsistencies over time The problem is not technical complexity. It’s lifecycle governance. So I built a structured approach to host decommissioning focused on: Drain validation Active session verification Controlled removal from host pool VM deletion sequencing Identity cleanup validation Registration token rotation Logging and execution safety I’ve published a practical framework here: The framework is fully documented and includes validation logic and logging. https://github.com/modernendpoint/AVD-Host-Decommission-Framework The goal is simple: Not just removing a VM — but preserving platform integrity. I’m curious: How are you handling host lifecycle management in your AVD environments? Fully automated? Manual? Integrated with scaling plans? Identity cleanup included? Would love to hear how others approach this. Menahem Suissa AVD | Intune | Identity-Driven Architecture
