title: SQL Server Error 5123 When Attaching Database
body: <p>I have two databases. Both are in the same folder. Both have, as far as I can tell, the exact same ownership and permissions. I can attach one but not the other - I get an error 5123.</p>
  
  <p>For both files...</p>
  
  <ul>
  <li>Owner is MSSQLSERVER</li>
  </ul>
  
  <p>Permission entries:</p>
  
  <ul>
  <li><p>MSSQLSERVER - Full control</p></li>
  <li><p>OWNER RIGHTS - Full control</p></li>
  <li><p>Administrators - Full control</p></li>
  </ul>
  
  <p>I reviewed the other question referenced below but could not get any of the suggestions to work given my constraints listed above. I posted what finally worked below.</p>
