As MSDN or Technet Subscriber you have the possibility to download and Install-DVD for Windows Storage Server 2008. Normally it will be shipped just by OEM’s. So when you want to play around with it like me, for example to use it as an iSCSI-Target for a Cluster-Lab you’ll be surprised that the installation finish without asking for a Administrator password. It just stops at the logon window.
The default Administrator password is “wSS2008!” (without the quotes).
