Issues installing SQL Server 2008 on Windows Server 2008 R2 I am trying to install SQL Server 2008 on Windows Server 2008 R2 Cluster. While installing the first node, I keep on getting the following error:


  TITLE: Microsoft SQL Server 2008 Setup
  The following error has occurred:
  Attempted to perform an unauthorized operation.
  Click 'Retry' to retry the failed action, or click 'Cancel' to cancel this action and continue setup.


Has anyone seen this issue before? I have uninstalled it multiple times and tried re-installing it but same results.
Thanks Aaron B. for the help. The issue seems to be with the server itself. I had SA reimage the server and now SQL installed without any issues.
