A HTTP 401.2 error page is sent....browse to http://64.79.4.26/and a logon popup appears.
Server: Microsoft-IIS/5.0 Hmmmm...!!

Let us get out the Old MCSE: Internet Information Server 4 StudyGuide.
A HTTP 401.2 error page is sent when one fails to Logon with properuser Account Name and a Password to a domain controller, the error defaultfor HTTP 1.1 standard. In this case the authenticate script has been disabled,otherwise if you browsed to http://www.habitablezone.com/ it would initiatethe script for logon.

If you use the IP address the script is initiated, and if you failwith the correct input ( ID and Password ) you get the error page. So wehave here a Virtual Website on a IP address that resolves to pluto.....
So there should be other Websites on this domain. Let us check nextdoor and see what 64.79.4.27 is ?

It looks like we're looking at RAS with either PAP ( Password AuthenticationProtocol ) or CHAP ( Challenge Handshake Authentication Proptocol ).
