Getting error while provisioning managed domain using PowerShell

Charbelhanna 

Thank you for your reply. I can provision from console but cannot do so using PowerShell from my system and PowerShell prompt of console. I have created dedicated subnets as well. Here is full script that I am trying.

Connect to Azure AD

Create Group, user and add user to group

Register-AzResourceProvider -ProviderNamespace Microsoft.AAD

$ResourceGroupName = "abhayadadds"
$AzureLocation = "eastus"

# Create the resource group.
New-AzResourceGroup `
-Name $ResourceGroupName `
-Location $AzureLocation

$VnetName = "abhayVnet"

# Create the dedicated subnet for AAD Domain Services.
$AaddsSubnet = New-AzVirtualNetworkSubnetConfig `
-Name DomainServices `
-AddressPrefix 10.0.0.0/24

$WorkloadSubnet = New-AzVirtualNetworkSubnetConfig `
-Name Workloads `
-AddressPrefix 10.0.1.0/24

# Create the virtual network in which you will enable Azure AD Domain Services.
$Vnet= New-AzVirtualNetwork `
-ResourceGroupName $ResourceGroupName `
-Location $AzureLocation `
-Name $VnetName `
-AddressPrefix 10.0.0.0/16 `
-Subnet $AaddsSubnet,$WorkloadSubnet

$AzureSubscriptionId = "My Subscription ID"
$ManagedDomainName = "Managed domain name"

# Enable Azure AD Domain Services for the directory.
New-AzResource -ResourceId "/subscriptions/$AzureSubscriptionId/resourceGroups/$ResourceGroupName/providers/Microsoft.AAD/DomainServices/$ManagedDomainName" `
-Location $AzureLocation `
-Properties @{"DomainName"=$ManagedDomainName; `
"SubnetId"="/subscriptions/$AzureSubscriptionId/resourceGroups/$ResourceGroupName/providers/Microsoft.Network/virtualNetworks/$VnetName/subnets/DomainServices"} `
-Force -Verbose
