SYMPTOMS

Consider the following scenario:

You create an Active Directory-integrated DNS zone on a Windows Server 2003-based DNS server.
You control which users or computers can create, change, or delete DNS records in this zone.
A DNS record in this DNS zone is deleted. However, the deleted record still exists as a tombstoned record in the DNS zone.

In this scenario, a user or computer that does not have permission to create DNS records in this zone can create a new DNS record that has the same name as the deleted DNS record. You expect this action to be denied.

CAUSE

This problem occurs because, when a DNS record with customized permissions becomes tombstoned, the permissions on the record are reset to the default value. Therefore, an unauthorized user can modify and re-enable the tombstoned DNS record before it is removed from the DNS zone.
