Hello Sham Raj,
Thank you for posting in Microsoft Community forum.
Please troubleshoot the issue as below:
1.Please check if you have a GPO named "Win2012-General-Server-Security-MS-SQL-COM-Policy" in Group Policy Management on DC.
The GUID of this GPO is "E417726A-4A78-4C44-A5A0-D59A2764CCDC".
2.Check where this GPO was linked (which OU or domain).
3.Are these 'SQLSERVERAGENT', 'RpcEptMapper', 'SystemEventsBroker', 'SQLAgent$SQL2K16U' computer names in your domain?
4.Check if the OU that this GPO linked has machines ('SQLSERVERAGENT', 'RpcEptMapper', 'SystemEventsBroker', 'SQLAgent$SQL2K16U' ) in this OU.
5.Check if you have configured any group policy preference setting within this OU.
6.Confirm do you still want to the group policy preference setting apply to these machines.
