SQL Always on DSC Failure

Hi guys i'm trying to deploy the https://github.com/Azure/azure-quickstart-templates/tree/master/sql-server-2014-alwayson-dsc template, it deploys all my resources but fails on provisioning the SQL VM Extension and i have no idea why :(

```
NewAzureRmResourceGroupDeployment :
Resource Microsoft.Compute/virtualMachines/extensions 'vm01SqlC0/sqlAOPrepare' failed
with message 'The resource operation completed with terminal provisioning
state 'Failed

NewAzureRmResourceGroupDeployment : VM has reported a failure when
processing extension 'sqlAOPrepare'. Error message: "Errors occurred while
processing configuration 'PrepareAlwaysOnSqlServer

NewAzureRmResourceGroupDeployment :
Resource Microsoft.Resources/deployments 'deploySqlAlwaysOn' failed with message 'The
resource operation completed with terminal provisioning state 'Failed`

```

`VMExtenstionProvisioningError, the VM has reported a failure when processing extension 'sqlAOPrepare' Errors occured while processing configuration 'PrepareAlwaysOnSqlServer'`

Start with the sql-server-2014-alwayson-dsc template and reproduce the deployment failure. Inspect the vm01SqlC0/sqlAOPrepare extension and the PrepareAlwaysOnSqlServer configuration, using the reported VM extension and nested deployment errors as the starting point. Done means identifying the provisioning cause and confirming a successful deployment.
