pls help me with pushing GP to my stations

I already configured the GP via C1 (the *.adm files) in the following
Zenworks --> Workstation package --> Policies TAB --> Windows XP -->
Windows Group Policy

I set the Policy Schedule : Event & System startup
I also set NDS Rights to TREE --> "name of Object"

But GP can't implement to my workstations

I don't know how to proceed from here & need your kind help

Zenworks --> ver 7
Workstations --> Windows XP SP1 & SP2

Best Regards
