cannot connect to SHUCHI
additional information: An error has occured 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 connection to SQL Server)(Microsoft SQL Server,Error:2)
