Windows 7: Simple GPO setting to Enable Command Prompt is overwritten by GPO 2?

Can't believe this doesn;t work.

I have Group Policy 1 which is linked to 2 OUs and i have the setting in it to Disable the Command Prompt and this works.

I want to enable the Command Prompt for 1 of the OUs, so I created another Group Policy and Enabled the Settings

So 1 of OUs had both Group Policies applied, and I have changed the link order so that the Group Policy which enables the Command Prompt is 1 so should be processed last and take affect.

But everytime I log in to a workstation in this OU, command prompt is always disabled.

I have tried switching link orders, enforce ticked, but it seems the disable command prompt is taking priority.

Anyone able to help get this working?

Thanks
