Stop me if I'm wrong as we don't use enterprise edition but isn't the media for workgroup and enterprise the same? I thought only express edition had separate media. Therefore is there any limit in the software? I thought it was just left to resellers etc. to enforce the restrictions on workgroup edition. I do see your problem with setting 8 CPUVPs to improve performance on a 8-way box but only wanting to use 4 CPUs and I don't have a solution. Ben.

It used to be, but now there is separate media.
