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.

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.
