NetIQ Group Policy Guardian 1.6
Group Policy Guardian does not detect explicit link deletions for Sites or OUs.
When deleting Active Directory Sites or OUs, Group Policy Guardian does not detect that the corresponding links have been deleted.
Group Policy Guardian does not detect indirect link deletions: for example, deletion of GPO links that result from AD container deletions.
This is a known issue and NetIQ is aware of this behavior.
