i tried to change my data base to sql express but i cant seem to get it to connect becuase it requires me to set it up for remote connections (which i did) but for some reason it isnt working. it is giving me this error.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
