Join domain script help

In this script why does it miss out joining the domain and just stays as a unknown workgroup. Here is the script i am working with.

<#
  Creates a Virtual Machine that is domain joined on boot
  Use Get-AzurePublishSettingsFile and Import-AzurePublishSettings file to import your subscription settings

  Pre-Requisites: Connected to an on-premises environment with AD
  OR
  AD deployed in another virtual machine and DNS configured.
