title: The request failed or the service did not respond in a timely fashion in sql server 2008 R2
body: <p>I am not able to start sql server 2008 R2 service . I cross checked all answers given here for same problem without any success. <strong>I disabled VIA protocal</strong>, still it didnot start. I tried using all options(local system, local server, network service) for login, but still nothing happened. I have SQL Server 2008 also installed and that is working fine without any problems. R2 was working fine , but due to unknown reasons it is not. </p>
  
  <p>I can't uninstall as I can't loose databases mounted in it. </p>
