Error=82 - ATP Service not starting

[Shaneil Narayan]

I have installed the ATP Sensor on a DC but the "Azure Advanced Threat Protection Sensor" is not able to start. Service is being run as "Local System".

Our internal AD domain is a ".net" and external Azure domain is ".com"

Seeing Error 82 in the logs.

@Shaneil Narayan , does svc_atp have read permission in AD06P.mydomain.net ?

Is this a multi forest scenario? is the sensor located in a different forest from AD06P.mydomain.net  ? If so, you need to provide credentials for each forest in the configuration page in the console UI.
