This has just started happening today. I'm using the WVD - Provision A host Pool in the Azure Portal. NOTE:- Same WVD tenant has been working even up until this morning.- I'm using a service principal to authenticate. This is also working.- Using the Windows 10 w/ Office template PROBLEM: I created a host pool earlier, however missed the domain config when setting up the deployment so it failed when trying to join the machine to the domain. I removed the resource group and all related resources in said group leaving my networks etc intact, and configured the deployment again. On validation, I am now getting the following error: Validation failed, see errors below. InvalidTemplateDeployment template validation failed: 'The template parameter 'baseUrl' is not found. It does not matter which of the supplied templates I use I have the same problem. Any suggestions or further info required?

WookieGTB : Thank you for reporting the issue. We are working have identified the issue and working on testing and publishing the fix.

praveenanil regarding the previous deployment template. It did seem to succeed with the deployment using an existing deployment template but the hosts did not register with the host pool. This is likely due to user error on my side but at least it got me further along so thanks for the help. Hopefully this is resolved soon.

Christian_Montoya Hi I first of all thank you for replying back I may have found why it gave me an error I used a blob storage vhd. and my storage account for the vhd was in different region to the resource grp so I am doing Azcopy and I will redeploy hopefully this will work. I will keep you posted.

I've just wiped my WVD tenant and set it up from scratch following along again with the guide here: https://docs.microsoft.com/en-au/azure/virtual-desktop/Even created a new Service Principal and can log into the WVD tenant with those credentials.Still having the same issue. I'm guessing MS is working on the VM templates and messed something up? Or am I missing something else.

I have the same issue here :( Logged a ticket irrepective

If you are using a free subscription, keep in mind we are only allowed to have 4 vcpu, so resize the pool sizeWookieGTB

  If you are using a free account you need to reduce your number of vCPU to 4 and also reduce the number of users.
  The default number of users is 100, reduce it to 5 or less.

I found a workaround, use Github template to provision hostpools.

You can findet link to template here https://docs.microsoft.com/en-gb/azure/virtual-desktop/create-host-pools-arm-template#run-the-azure-resource-manager-template-for-provisioning-a-new-host-pool

  I deployed yesterday a other way. You can create a pool with Az PowerShell. Afterwards you deploy W10 VMs from the Marcetplace and add them with 2 downloadable installers to the pool. You can find the manual on the same place as the other manual.

This is also happening to me. I have tried using different users, images (win10, win10 + office and win server) and different instances with the same result...

    Sejun Kim : We're actively working on the fix, but do not have a specific ETA at this time. In the meantime, I would recommend running our GitHub ARM template: https://github.com/Azure/RDS-Templates/tree/master/wvd-templates/Create%20and%20provision%20WVD%20host%20pool

  Just to let you know. I reported this issue through the CSP partner support channel and the Azure support Twitter account and both did reply that this is a preview and therefore no support will be done. I know that the SLA is that way, but if the community reports issues and the official support channels are not willing to help, this will not help anyone.
  
  For my case, we are in the middle of a proof of concept for a customer and after the reactions from the support we can't recommend anymore this offering to them. Yesterday everything went fine and today everything failed while the deployment.
  
  Best, Marco

  Great, thanks. I am hoping to run a client demo with this today so hopefully it is working soon.

    Devan10 Looks like it will take us more time to provide the fix for the template. We will keep you updated.

I have the same problem. Support is declining any help as this is a preview program they say.
