Cannot get ATP sensors to Start
Seth Holek uninstall and reinstall to make sure the service is deployed correctly, this is broken because you changed the services logon... it is unable to retrieve the gmsa password this way,
the gmsa should only be configured on the portal, the system takes care of all the rest...
MicrosoftSeth Holek , you should find the clues in the sensor's own logs folder, not in the windows event log.
Just to be clear, the gmsa account was configured in the portal right? you didn't change the actual windows service, did you ? the sensor should run with it's pre configured virtual account (which inherits local service)
Yes, I added the gmsa account to the Directory Services credentials in the Portal, and I did change the service from Local Service to the gmsa account.
Here are errors from the ATP logs:

EliOfek Thanks. I reinstalled the Sensor on both my DC's, and was able to get it work on the DC in Azure, but I still cannot get it to work on my local DC. I did the same install process for both DC's, but am still getting the same errors I listed below. Is there a particular port on the firewall that needs to be opened up, or am I off base with that?
