See the 080 port, do not see too understand, how should solve?

8080 is the port of the Project Access server is not the database access port number changed to 1433 after the error

Workaround: from "All Programs" in "Start", open the SQL Server Configuration Manager (configuration Management) for Microsoft server 2008R2 , and then enable the TCP/IP protocol.

Next, restart the database service: computer-management-services and applications-start the database service
