I am getting the same error, but the Provider is TCP (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: TCP provider, error: 0 - An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.) )

Hi Pinal,

I am getting the same 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) ) for one of my application on running on SQL 2000 on OS Window 2000 Terminal.

I tried and tested all the possibilities but all were unsuccessful.

The same Application is running successfully on other server having same configuration.

Please help in above matter.
