Apply GPO on a PC in another OU

Hi!

We need to apply a GPO to a Computer which is in a different OU than the main OU where the GPO is applied. We created a Security Group in the main OU and added that pc in that OU but still the GPO is not applying as the PC is in a different OU. We don't want to move the pc to the main OU.

Any Suggestions?

Thanks.
