Able to connect via local host but not server

I have a page that connects to SQL server. It works fine when running in local host but when I publish to the server, I get the following:

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)

Any ideas on where to start?

Thanks,

Mark
