Dear Vijay, if the issue is not solved please do not make it verified solution. You’d probably miss the chance of getting help. Now, for the issue that you are facing it prompts to refer the event log for more information right. Why don’t you paste the event log message here for better understanding of exact problem you are facing. ---
