title: SQL Server 2005 database to 2008 R2 migration issue
body: <p>Recently we migrated our SQL Server 2005 database to 2008 R2. After that we are facing lots of issues</p>
  
  <ol>
  <li>A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) .</li>
  <li>The timeout period elapsed prior to completion of the operation or the server is not responding</li>
  <li>A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) .</li>
  </ol>
  
  <p>We removed all firewalls , added connect time out in connection string etc.. but issue is still pending. It will coming in randomly why this is happening? thanks</p>
