Add connection error: 40

Hi i just reinstalled windows, and installed visual studio .net 2005 and the Sql server.

But when im trying to add connection, select my computer at Server

name, type a databasename then pressing OK i get this message:

An error has occured while estabilishing a connection to the server.

When connection to SQL server 2005, this faliure may be caused by the

fact that under the default settings SQL Server does not allow remote

connections. (provider: Names pipes provider, error: 40 - Could not

open a connection to SQL Server)

Does anyone know what todo?

hermanTry this: open the SQL Server Configuration Manager, expand SQL Server 2005 Network Configuration, highlight protocols for MSSQLSERVER and enable TCIP/IP.
