Our issue is not caused by network connectivity, as the patch is already installed and there no old hidden NICs. Also, the issue occurs with Windows 10. Also, our pools will eventually provision correctly after retrying. In our vmware-viewcomposer-ga-new.log, customization seems to be failing when running nltest.exe /sc_change_pwd with an "ERROR_NO_TRUST_SAM_ACCOUNT". There seems to be some sort of timing issue, as the machines will eventually run customization successfully. Our AD sites are set up correctly, though we do have multiple domain controllers per site. Linked clones work fine. Does anyone actually have instant clones working outside of a lab environment? VMware, anything you can add here??
