title: Changing the 'Server Collation' after installation
body: <p>I want to change the Server Collation of SQL Server 2008 R2</p>
  
  <p>As all opinions says (including MSDN) the following command should be executed:</p>
  
  <blockquote>
    <p>E:\setup.exe /q /ACTION=RebuildDatabase /INSTANCENAME=MSSQLSERVER /SAPWD=”<strong>**</strong>″ /SQLSYSADMINACCOUNTS=”HEREISMYPROBLEM” /SqlCollation=SQL_Latin1_General_CP1_CI_AS</p>
  </blockquote>
  
  <p>As I Pointed, my problem is with the SYSADMINACCOUNT paremeter because the error that I get is:</p>
  
  <blockquote>
    <p>The Windows account ”blablabla” does not exist and cannot be provisioned as a SQL Server system administrator.</p>
  </blockquote>
  
  <p>I tried all possible windows accounts that may be, but It's not working.
  Please can you guide me how to know my correct windows account.</p>
