This error due to the named pipe support is not enabled for your SQL server.To enable named pipes or for workarounds see the link http://msdn.microsoft.com/en-us/library/ms175496(v=sql.110).aspx hope this will help

Hi Riddhi, https://technet.microsoft.com/en-us/library/bb896140%28v=sql.110%29.aspx Sql Compact is very light and mostly used for mobile app. Sql Server is better for back -end.

Hope you are enable named piped by following steps. In start menu, go to sql server xxxx/ Configuration tools/ Surface area configuration Select Surface area configurations and connections Remote Connections On the right see named pipes is selected or not.
