Currently we are using vCenter 6 Update 1a with ~110 host ESXi 5.1 - 6. We deploy all Windows Vm from SYSprep'd templates. I am trying to make things more efficient and use Gust Customizations the problem I have having it that after the VM starts up, I have to re-enter in all information and none of my settings that should been there are not. For example, the Guest OS's name should be the same as the display name and it is not... but the generic random Windows name.
1) I have tried to select the option of edit customization and go through the wizard during deployment and had the same effect
2) Tried to uncheck the "Generalize SID" option but when I deploy a VM is would through an error because this was not selected yet still deploy the VM but still not setting applied.
3) Tried to deploy a VM from a non-sysprep'd image and had the same problem
4) Different OS version Windows 2008 - 2012 same problem
Now I did not upload any sysprep files to the vcenter server and believe someone before me started to play with this a while back so I am not sure if there could be a factor. Any thoughts or suggestions?
