title: Security Principals missing in SQL Server 2008 R2
body: <p>SQL Server 2008 R2 on Windows Server 2012 R2, none of the built in security principals are appearing when trying to view user accounts and assigning permissions. </p>
  
  <p>They are available on the service to assign the LOGON as value. Specifically I am looking for <code>NETWORK SERVICE</code>.</p>
  
  <p>FOR CLARIFICATION: I am referring to the local accounts <code>IUSER</code>, <code>NETWORK SERVICE</code>, <code>LOCAL SYSTEM</code>, etc.

  <p>I just completed a parallel installation on a demo server with no issues both 2012 R2 boxes. The one with issue is a VM.</p>
  
  <p>And just to confirm, the accounts DO IN FACT exist on the server. So they were created during the OS install.</p>
  
  <p>I uninstalled an reinstalled both SQL Server and SSMS, both back up and running, same issue.</p>
  
  <p>Any ideas on how to get those back?</p>
