Hello Jim,
Based on my own understanding for the
ATA Licensing datasheet, the number of licenses you need will depend on:
- The domain controllers you configure ATA to monitor
- The user or user devices contained in the AD forests or domains that are managed by those domain controllers.
Therefore, if you configure the ATA to monitor the domain controllers in the internal domain only, your calculation is approximately correct. Please note that you only need to pay once, not for each year.
Since this is a sales question, I would recommend to contact Microsoft representative for getting better support.
Best regards,
Andy Liu
