We are creating ArcGIS Enterprise Portal Site on a machine (Windows 2016 standard OS - 4 core virtual machine). installation is completed successfully. However, while creating the site following error is displaying:

"There was an error creating your initial administrator account.

Index Service configuration failed."

I attaching the log file generated. 

Any idea, what is going wrong??

We are able to solve this by disabling the antivirus on the server.
