VM DSC Extension - Repository doesn't match Reality
Hi, I am provisioning VMs as session hosts for AVD, using Entra ID for login. During the deployment process, one of the resources is Microsoft.Compute/virtualMachines/extensions/Microsoft.PowerShell.DSC. Based on the deployment information, the artifacts (scripts) that are being used come from this path: https://wvdportalstorageblob.blob.core.windows.net/galleryartifacts/Configuration_1.0.02893.601.zip The confusing part is that when I view those files, they are a bit different than the ones stored in the Azure GitHub repo here: https://github.com/Azure/RDS-Templates/tree/master/ARM-wvd-templates/DSC Is the GitHub repo just out of date or need review? I have questions on the implementation of the scripts, but it seems like figuring this out is the necessary first step.DSC error(s) deploying session hosts - Resolved
I had several issues with DSC Configuration failures , conflicts, client cannot connect to the destination specified etc. Was occurring with the Microsoft catalog and my own images. The last bit was after my firewall guys were certain it was not them. "VM has reported a failure when processing extension 'dscextension'. Error message: \\\"DSC Configuration 'AddSessionHost' completed with error(s). Following are the first few: The client cannot connect to the destination specified in the request." This is the workaround for me. Waiting on Microsoft support to weigh in see if it a bug etc. Test this in your lower environments! 🙂 Create a new VM from your disk template. I suggest you create a separate RG for workspaces. Disable IPv6 on nontunnel interfaces (except the loopback) and on IPv6 tunnel interface https://support.microsoft.com/en-us/help/929852/guidance-for-configuring-ipv6-in-windows-for-advanced-users use the fix it. Sysprep , genralize, OBE, shutdown. Convert the VHD to an Image (your mojo) $disk = Get-AzDisk -ResourceGroupName 'your-rg' -DiskName 'your-disk' $location = 'South Central US' $imageName = 'golden-image-name-ipv6-disabled' $rgName = 'your-rg' $imageConfig = New-AzImageConfig ` -Location $location $imageConfig = Set-AzImageOsDisk ` -Image $imageConfig ` -OsState Generalized ` -OsType Windows ` -ManagedDiskId $disk.Id $image = New-AzImage ` -ImageName $imageName ` -ResourceGroupName $rgName ` -Image $imageConfig Deploy new Host pool and Session hosts with the new image
