I got this error while installing a local product created in .net as front end and SQL server as back end. Everything was seems working while I try to connect to the SQL server but application was not able to be installed on the client system. I followed the under given settings for opening the ports for the network:

- SQL Server Network Configuration
- Protocols for SQLEXPRESS
- Right clicked on TCP/IP
- In the TCP/IP Window
- Go to option IPAll
- and then enter 1433 in TCP Port text box
