title: Database MSDB can not be opened
body: <p>I have got this problem in local instance of SQL Server 2008 R2 on my machine. There are several databases on this instance. But I am not able to see any of them from the object explorer. </p>
  
  <p>I am able to query my databases from the new query window. But not able to see any of them.</p>

  <p><em><strong>Database 'msdb' cannot be opened. It has been marked SUSPECT by recovery. See the SQL Server errorlog for more information. (Microsoft SQL Server, Error: 926).</em></strong></p>
