I have solved the problem, using ADSI tools (from 2k support tools) by expanding Domain NC/Cn=System/Cn=Policies and opening CN=(xxxxxxxxxxxxxxxxxx)/CN=machine/CN=Class Store/CN=Package. In the right pane, i had to double click on the CN which have no "packageregistration" displayed under Class. Then open Security Tab, and adding the correct users and give it Full control.

I have create a new installlation package using GPO, and i have remove security rights on this GPO. Now this GPO is no more displayed using GPMC or ADS user and computers. How could i restore rights to edit this "lost" GPO. Thanks for your support. Dave.
