Hi Niall, thanks for the great guide, I have managed to complete all of the steps using the powershell scripts apart from the SCCM install, it fails at the same point, I checked the logs from the failed install and it say the same thing each time "setup has encountered fatal errors during database initialization. check the log for details. click the view log button for more information"
I have checked all of the permissions on the server and the SQL account permissions, have you come across this before?
