What uses the ANONYMOUS account - it's not defined (shown) in the user
manager list and yet I see logons having occurred within the Event Viewer's
security tab. I think I can disable it using the Group Policy setting, but
what will I break if I do so ? If nothing, then why was W2k distributed with
it set in the first place ?
