Hello Himanshu Dwivedi,
Thank you for posting in our Q&A forum.
1.I have created GPO with Allow login through remote desktop under Computer Configuration User Rights Assignment.
For this GPO setting, you should link this GPO to an OU with client PCs.
2.And then configure "adding the domain user to this gpo setting and forced that gpupdate.
3.Add the domain user accounts into local Remote Desktop Users group on the client PCs.
4.Check if you can login the client PCs via RDP.
Hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
