I'm having some issues with this, I've setup the customization I want with "virtual machine name" being the guest host name, and added in the credentials to add the machine to the domain, but after deploying from template, selecting the use customization and my 2012 customization what happens is the machine boots - reboots, comes back with the correct host name but doesnt bring the machine onto the domain, instead its still on "Workgroup".
If I then manually add the machine to the domain with the same credentials as supplied in the vmware customization manager the machine goes onto the domain, would be nice to have this as an automatic process though, has anyone encoutered similiar issues?
