Hello Sham Raj,
Thank you for your reply.
I just want to understand what are those names?
They should be service name.
Please edit the GPO named "Win2012-General-Server-Security-MS-SQL-COM-Policy" in Group Policy Management on DC, expand Computer Configuration, Preferences, Services. Check if there are service entries ('SQLSERVERAGENT', 'RpcEptMapper', 'SystemEventsBroker', 'SQLAgent$SQL2K16U'), if there are actually these services under Computer Configuration, Preferences, Services, if you do not need them, please delete it and then check the result.
If you still need them, you cannot delete them.
Best Regards,
Daisy Zhou
