​I am trying to onboard Microsoft Defender for Business by using the onboarding script “WindowsDefenderATPLocalOnboardingScript.cmd”As I use Admin to run it, it just shows “Unable to start Microsoft Defender for Endpoint Service. Error message: The Service name is invalid”I tried to find the ATP service but I did not find the service has anything to do with “Windows Defender ATP”. Also I did not find the same Error message in the help document though we have the same error number.I tried to reference thehttps://answers.microsoft.com/en-us/insider/forum/all/unable-to-start-microsoft-defender-for-endpoint/854aec41-ff21-4daa-8321- b7a4eb9ba5cdfor the solution, but it doesn’t work.Output log:C:WindowsSystem32>”D:DownloadsGatewayWindowsDefenderATPOnboardingPackage(3) WindowsDefenderATPLocalOnboardingScript.cmd” This script is used to enroll the machine in the Microsoft Defender for Endpoint service, including security and compliance products.
