SYMPTOMS
Creating a new zone file in Domain Name System (DNS) could compromise the name of the Administrator account, even if the Administrator account has been renamed.
CAUSE
When you create a DNS zone, the name of the logged-on user is automatically placed in the Responsible Person field in the Start of Authority (SOA) property for the new zone. If you log on with the Administrator account, or with a renamed Administrator account, that account name is placed in the field. Because this name is publicly accessible, it could give a malicious user a way to learn the logon name of the administrator who created the account.
