Messing around with AVD and AADJoin

In a previous post: Messing around with WVD, AADDS and FSLogix – Albandrod’s Memory (albandrodsmemory.com) I was talking about how AVD breaks some scenarios and how we could fix them.

In this ocassion I will talk about my experience working with the new version of AADJoin for AVD which is finally in public preview. So with this approach we can eliminate the need to have a domain controller or AADDS in place for your AVD deployment to work, but as you can imagine it has some drawbacks.

First important thing that you have to be aware of implementing this type of scenario is that when you’re adding the VMs to the HP, it is necessary to select the following option:

Also is important to check wether is we want to join the VMs to Intune or not, in my case I selected yes, and after a few moments of the VM creation, I was able to see it in the endpoint portal:

After you have created the HP, my recommendation would to configure it, you can use the following advanced RDP properties:

use multimon:i:0 which basically Determines whether the session should use true multiple monitor support when connecting to the remote computer

To access Azure AD-joined VMs using the web, Android, macOS, iOS, and Microsoft Store clients, you must add targetisaadjoined:i:1 to the HP. These connections are restricted to entering user name and password credentials when signing in to the session host.

But, what is more important for me, and it was driving me crazy at first, it was the authantication in AVD AADJoined:

The following configurations are currently supported with Azure AD-joined VMs:

  • Personal desktops with local user profiles.
  • Pooled desktops used as a jump box. In this configuration, users first access the Azure Virtual Desktop VM before connecting to a different PC on the network. Users should not save data on the VM.
  • Pooled desktops or apps where users don’t need to save data on the VM. For example, for applications that save data online or connect to a remote database.

So, don’t break your head trying to authenticate with your current user as in WVD Joined Domain, you will need to use a Local profile for AzureAD Joined VMs, if not you will receive an error like the following which will drive you nuts:

But after using the local user in the VM you will be able to log in the VM.

Once you log in to the VM, you can check the dsregcmd to see the status:

And also how the machine is enrolled in Intune, you can check the information regarding the enterprise registration 🙂

For me AVD AADJoin, it is a pseudo Windows365 but with custom images and without paying the full license to access to the resource itself. The other things about AVD and AADJoin are pretty the same as Domain Joined, so have fun with them

Till next time!

Messing around with WVD, AADDS and FSLogix

In a project where WVD was involved, we needed to implement AADDS and FSlogix to the scenario. If you take a look to that scenario, it is pretty simple, but it hides some stones that we hit during the road, so I want to explain them in this post 😊

First of all, once you have deployed the AADDS, remember to check DNS settings in the VNet, it is necessary to put the DNS from the AADDS, otherwise won’t be possible to join VMs to the AADDS domain:

Once the AADDS instance was deployed it took turn for the golden image, as you probably know there is no problem to install all the programs and updates, but our stone here was once we deployed the language pack and the image was prepared, the sysprep was crashing, so we need to deep dive into the logs to solve the problem…

So the deployment begun to be fun, but after digging, we were able to solve by executing…

Remove-AppxPackage -Package Microsoft.LanguageExperiencePackes-ES_19041.17.51.0_neutral__8wekyb3d8bbwe -AllUsers

And then… boom!

Probably you will need to change your package in your case but is important to include the -allusers parameter.

Solved the golden image problem, it take turn to the deploy the host pool which process was straightforward. Our next stone was the storage account… ☹

Deploying the storage account into the AADDS was easy, but the problem was to give NTFS permission to the users, we were used to do that process in ADDS scenarios, so we know what to do, but with AADDS the procedure changes a bit…

So my piece of advice, would be to follow the instructions given in docs: Uso de Azure AD Domain Services para autorizar el acceso a los datos de archivo a través de SMB | Microsoft Docs

We were using the AAD credentials and we were stuck for a while until we read this in the documentation. Lesson learned, read documentation help.

Once you have entered to the storage account with your storage account key, you are able to give NTFS permission to the users (please follow instructions from docs xD)

Once we solved this, we were in position to configure FSLogix for the mobility of the profiles. For those who do not know FSLogix it allows to store both user profiles and applications on a centralized file share. This is extremely useful in virtual desktop environments, as the user’s profile does not have to be copied prior to boot. FSLogix will mount those profiles hosted on a file share and will make them appear local.

But again, once we have configured the entry in the VM registry:

We hit another stone… because we were logging into the WVD remote desktop and it didn’t create any profile on the Storage account, after digging and asking ourselves, we decided to go to FSLOgix logs located here: %ProgramData%\FSLogix\Logs. We checked the profile logs and found the following:

Configuration setting not found: SOFTWARE\FSLogix\Profiles\AttachVHDSDDL. Using default:
[17:33:52.257][tid:00000c4c.00000e74][INFO] Session configuration wrote (REG_SZ): SOFTWARE\FSLogix\Profiles\Sessions\S-1-5-21-1901185187-4119977032-3365905087-1004\AttachVHDSDDL = ‘D:AI(A;;GA;;;SY)(A;;GA;;;BA)(A;;GA;;;BU)(A;;GA;;;WD)(A;;GA;;;RC)(A;;GA;;;AC)S:(ML;;NW;;;LW)’

Probably you will asking yourself what kind of error is that? It is simple, your local profile is messing with the network profile being created, so what we had to do is to remove the local profile. You can do that by going into advanced system settings and deleting the profile

We did that, and we tried again and booooooom! The profile was created in the storage account:

After doing that, we were in position to do all the test in WVD and then di all the steps to create and enterprise environment (optimization, monitoring, a “true” golden image, hide the power button, etc…).

Till nex time!
