Since 8.5 RU2 FQDN appearing in Unattend.xml

Hi all,

We've recently updated to 8.5 RU2 (from 8.5) and also updated the Windows ADK to the 1809 flavour. Since then, we've found that the token replacement on the Unattend.xml file is putting the FQDN into the file instead of just the COMPUTERNAME. This is causing our domain joins to fail. Anyone else seen this or able to suggest why it's started happening? This was all fine on 8.5 and an earlier ADK.

Thanks

Martin
