Group policy is not getting affected.

Hi,

I have screen lockout policy configured in default domain policy. It is getting applied and affected  throughout my domain except one ou. For troubleshooting I logged in with multiple account on the computer of that OU but still not effect of policy. Even I logged with a test account and run the RSOP.MSC. And after that I checked that lockout policy showing applied but not getting affected on that machine.

Regards,
