Problem Security on object in AD!!!

Hi,

I have a domain policy on which i have one corrupted object.This object is
Office XP installation package.When i open that group policy and go to User
configuration/Software settings/Software instalation i don't see that
package.*** using ADSI edit i found that object in container
System/Policies/ID of policie/User/Class store/Package.



When i try to delete it it says The specified directory service or attribute
does not exist.How to solve this problem?



Thanks in advance
