I have a VM (with ADDC and DNS) in a cloud service (cloudservice1).

Here is the command

$dns1 = new-AzureDNS -name dns1 -ipaddress 10.24.100.100
$vm1 = New-AzureVMConfig -Name 'testAdvm' -InstanceSize Small -Label testAdvmLabel  -ImageName  $img1 
Add-AzureProvisioningConfig -WindowsDomain -Password password1 -JoinDomain domain.com -Domain domain -DomainUserName domain\administrator -DomainPassword password1
New-AzureVM -vms $vm1 -ServiceName cloudservice1 -DnsSettings $dns1
