Use the following steps to resolve your issue

·         Check if the server is responding by ping command

·         Check the configuration of the firewall

·         The  TCP port or the pipeline has to be specified in the connection string

·         Check whether SQL Server Browser Services are enabled.

·         Check if the port UDP 1434 is open in the firewall
