CreateADForest Conflict - WS 2016 TP4 Deployement Failure

My deployment on Windows Server 2016 Technical Preview 4 failed during the configuration of the new forest. Just sharing in case there is any incompatibility which you might want to know about sooner than later.

Status: Conflict - Provisioning State: Failed
Type Microsoft.Compute/virtualMachines/extensions
Resource Id: CreateADForest

{"status":"Failed","error":{"code":"ResourceDeploymentFailure","message":"The resource operation completed with terminal provisioning state 'Failed'.","details":[{"code":"VMExtensionProvisioningError","message":"VM has reported a failure when processing extension 'CreateADForest'. Error message: \"DSC Configuration completed with error(s).\"."}]}}

Start with the CreateADForest VM extension deployment and the reported DSC Configuration error on Windows Server 2016 Technical Preview 4. Reproduce the failure and identify a confirmed compatibility cause or validated template change; the issue names no file or test.
