Need help to applying GPO to a OU users.

Hi,guys
In my domain i create a new OU & add a policy to disable command prompt to the members of the OU.After that i applied gpupdate /force.But from my client pc i can access the command prompt even i restart the system but no luck. I run a gpresult from client it shows "the policy object does not exist" .
I stuck here for last two days Please guide me ,thanks in advance.
