Virtual Machine is unnable to join to domain using Powershell cmdlets

Hi All,

I'm creating a Virtual Machine in IAAS preview environment throught New-AzureVM cmdlet. However I'm unable to join my VM to a domain. I followed the tutorial which shows how to create a active directory forest and how to join VM into the domain at the time of provisioning. Here are the commands I'm executing in the Azure Powershell Command prompt:

$appvm3 = New-AzureVMConfig -Name "<VM_Name>" -InstanceSize Small -ImageName "<VHD_Name>" -MediaLocation "<URL Of VHD>" | Add-AzureProvisioningConfig -Password "password" -WindowsDomain -JoinDomain "abc.xyz.com" -Domain "abc.xyz.com" -DomainUserName "ankit" -DomainPassword "password" | Set-AzureSubnet Subnet

New-AzureVM -DeploymentName Win7VM1 -DnsSettings (New-AzureDns testdc 192.168.1.5) -VNetName VirtualLabNetwork -ServiceName appvm3 -AffinityGroup VirtualLabsGroup -VMs $appvm3

When I execute the above command, I get "The specified dns name is already taken".

I've tried removing -DnsSettings in the New-AzureVM command but that too is not working for me.

Please suggest if I'm doing anything wrong here.

However, manually, I'm able to join the domain.

Thanks
