ErwinManuel,

I'm sorry to hear that you are experiencing issues with the enable nested virtualization script. It sounds like you found a work-around at least?

Does this happen when you publish a template with a shared username/password or when you publish a template where the student sets their own password? I would like to do a little experimenting on my end and update the script. Maybe add your solution to the official script?

Thanks,

Elizabeth

Hi Elizabeth

Yes, the workaround is working well. The template is using a shared username and password.

Cheers
Erwin.

  ErwinManuel,
  
  Thanks for the information. I'm the glad you found an effective work-around.
  
  I did a little research, and I think adding
  
  Set-Service -Name WinNat -StartupType Automatic
  
  will fix the problem. It's essentially the same thing your workaround does. I'm going to do a little more testing and then submit a fix to the official script. I'll update this thread when this is done.
  
  Thank you for bring this issue to our attention. I appreciate it.
  
  Thanks,
  
  Elizabeth

    Perfect! Makes sense to have that service running at startup.
