Please note that installing the Azure ATP Sensor on Server 2019 is currently not supported. We are aware of some customers who have experienced issues with Domain Controller operation in this configuration. While the issue is not directly related to Azure ATP code, the Windows team is working on a resolution which will be solved as part of a future update rollup for Server 2019. Until the Windows fix has been released, and the Azure ATP team has completed their testing, the Azure ATP sensor should not be installed on Server 2019.
