Hello jim,
Thank you for posting in our Q&A forum.
Here are my suggestions for your references:
Way 1
If you are trying to do some tests, you can do as below:
1.Create on new OU.
2.Move this one host to this new OU.
3.Link this GPO with hundreds of settings to this OU.
4.Run gpupdate / force on this host or restart this host to refresh the GPO setting.
5.Check the GPO application is fine.
If it is OK, you can remove this host to the original OU and link this GPO to the original OU.
Way 2
If you only want to this this GPO with hundreds of settings to one host in the OU (this host can not be moved to other OU).
You can set Security filtering on this GPO.
Do not remove "Authenticated users", make Authenticated users have "Read" permission.
Add computer group. make computer group have "Read" and "Apply group policy" permissions.
Hope the information above is helpful. If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
