SCCM: CMG Provisioning Failed

Microsoft published an interesting Lab Set for Modern Desktop Management. Between projects I decided to install the kit and try Labs.

Here are some gotchas:

1. If Azure Account does not have an Azure Subscription in its own directory CMG installer cannot see the Subscription. Even if the account has rights to another subscription. I needed to create a new rial subscription linked to the same AAD to be able to proceed.

2. Even after that CMG provisioning failed. I checked the logs and found that Microsoft decided to not register Classic Compute (yes, CMG still uses Classic model). TO fix that I ran Powershell in Azure Portal and register requred provider:

register-azurermresourceprovider –providernamespace “Microsoft.ClassicCompute”

will see what additional surprises MS prepared…
