iMacs not shutting down from xserve
Before anyone shouts at me for not noticing the solution for, what might be, a simple problem, I haven't been working with Macs for long at all, I prefer Windows :D.
However, the problem is;
We have a medium size Mac network with an Xserve with Leopard (10.5.4) and about 50 client iMacs also with leopard (10.5.5) and are currently trying to set all the clients to shut down every evening using the workgroup manager on the Xserve, but when I return in the morning they are all still awake.
All the clients are in groups for the departments the are used in (Music and Art for example).
I have not only set the energy saving schedule in each machine group, but have also set the schedule for each indevidual machine in the workgroup manager, still doesn't want to know and stays on all night.
The schedule hasn't been set on all the machines locally as I thought it would work just from the Xserve.
Anyone know of this happening else where, or what could be going wrong?
