Azure Virtual Desktop planning - a little guide (please don't underestimate planning)!
Dear Azure Virtual Desktop friends, Again and again I encounter Azure Virtual Desktop infrastructures that were obviously poorly planned. Not only is performance poor, but security has been neglected and scalability is simply not possible. With such infrastructures, it is then simply impossible to get everything up and running again with a few adjustments. For this reason, I have tried to create a possible planning guide in this article. Let's start with the following points: Define objectives and requirements: -> Determine the purpose of the Azure Virtual Desktop infrastructure -> Identify the applications and resources required for end-users -> Establish performance, availability, and security goals -> Assess network connectivity and bandwidth requirements https://learn.microsoft.com/en-us/azure/architecture/example-scenario/wvd/windows-virtual-desktop

https://learn.microsoft.com/en-us/azure/architecture/example-scenario/wvd/windows-virtual-desktop Assess existing infrastructure: -> Evaluate current on-premises infrastructure and applications -> Identify any potential compatibility issues or bottlenecks -> Determine if any applications or services need to be migrated to Azure

AVD remote desktop client Bug
Remote desktop client when connected to AVD workspace, breaks desktop application drop down list and pushes it in upper right corner of the screen. Only reproducible in Remote desktop client, everything works as expected in web client. Remote desktop client: 1.2.4240.0 (x64) Bug Screen Shot. Expected behavior.Azure Virtual Desktop in the "cloud only" variant and what to look for after initial deployment!
Dear Azure Virtual Desktop friends, Imagine the following Szeanrio. You have decided to build Azure Virtual Desktop in the cloud only variant. With all the pros and cons. You have decided to set up a first test environment. Of course, all necessary licenses are also available! The provisioning of resources in Azure is done. For the DAG (Desktop Application Group), you have added a group from Azure Active Directory. There are two persons in this group. You start the Remote Desktop Client and log in as a user who exists in this group (as seen before). Double click on SessionDesktop and you will get an error message. Sorry, this is in German! The login attempt has failed! Why does the connection not work? The group has been added to the DAG what is still missing? What is missing now are the infrastructure permissions. What is not quite obvious, but unfortunately often forgotten. But one after the other. 1. If the host you are using to connect is not Azure AD Joined in the same tenant, the Advanced RDP settings must be extended. With the following value: targetisaadjoined:i:1 Next, other permissions need to be set up. I like to use the resources group for this. You can of course also set this up on the subscription. The following permissions are required: Desktop Virtualization Application Group Reader and Virtual Machine User Login Now back to the Remote Desktop Client and voila, the connection to the session host is now working. I hope this information helps you and you can successfully build an Azure Virtual Desktop "cloud only" infrastructure. The example here is of course not a finished setup, there are still apps, profiles, etc. missing. But it should help you get started. Thank you for taking the time to read the article.

Dear Azure Virtual Desktop friends, If you want to set up Azure Virtual Desktop infrastructure in Azure and you have chosen Azure AD Join and with Enroll VM with Intune, you may get the following error message: -------------------- [{"code":"VMExtensionProvisioningError","message":"VM has reported a failure when processing extension 'AADLoginForWindows'. Error message: \"AAD Join failed with status code: -2145648509. AzureSecureVMJoinOperation: DeviceEnroller::AzureSecureVMEnroll failed 0x801c0083.\"\r\n\r\nMore information on troubleshooting is available at https://aka.ms/vmextensionwindowstroubleshoot "}]} -------------------- This could possibly be because you have reached the limit for adding devices to Intune. You can find this information in the Intune Admincenter and increase the value. Either edit the default settings or set up a new Restriction policy. I realize it's not super, great, extra news, but I ran into these limitations during a deployment and the hints weren't necessarily obvious. Thank you for taking the time to read the article.

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 Architect
Mouse pointer disappearing over Word/Excel/Outlook in AVD
Hi We are seeing a strange issue on a bunch of session hosts where user over certain apps cannot see the mouse pointer in their full screen AVD sessions. Session hosts are running Windows 10 22H2 up to date (well to February B week release); user client up to date, I am not aware we had user ever report this prior to completely rebuilding a new host pool last autumn for the AppReadiness crashing issues. From what we can tell this only seem to happen with Microsoft Excel, Word and the Outlook compose window, the mouse pointer basically becomes transparent as you can't see it so it makes it hard to select text or cells accurately. Clients are mostly a mix of HP and Lenovo PCs micro PCs running Windows 10 22H2 and Windows 11 23H2 Enterprise on Intel 8th to 12th Gen CPUs and AMD Ryzen Pro CPUs with integrated graphics. Does anyone else see this or any ideas what might be causing it?How to fix error in AVD with VMs not being added to host pool or AD
Problem Several users have commented and posted on different networks about the error that appears when adding virtual machines to their host pool, the error is when the VMs want to join to the AD. The first thing we need to know is that if we add or create a new hostpool (as in my case), the deployment will tell us Azure that everything is correct, that is, as if the machines have joined the AD. Here I show the deployment with everything correct. Now if we check the status of our hostpool machines, we will see that it tells us the total number of VMs and the option of which one we can connect to and which one we cannot. In my case we see that we can supposedly connect to one and not to the other. When testing the connection, it fails on both machines. This is normal since if we check the health status of both we see the following. Basically it tells us that there is a problem joining the domain with the VM. Solution Below I show the solution that has worked for me, from different tenants, different subscriptions that had the same problem. We are going to go to our subscription and in it, in the setting section, we are going to click on Resource provider as shown in the following image. Next we look for the provider "Microsoft.DesktopVirtualization" We select it and then click on "unregister" Now what we are going to do is re-register, that is, we click on "register" Confirm that register is correct again. Now we deploy AVD again and add the VMs we need to our Hostpool, and in this case I have chosen Enter ID to do the Join *you can select your preferens) Validate de new deployment As we see here, the deployment has also indicated that it was correct, so we are going to confirm it. Here we can see that we already have the machines ready for the session. I hope this helps you solve the problems you are having with VMs and hostpools.
