I installed SQL Server 2008 on my Acer Aspire 5739G notebook. I installed a default instance but named it "SQL2008A". But when I tried to connect to the server, I received the message "Cannot connect to MSSQLSERVER. A Network-related instace-specific error occurred while establishing a connection SQL Server. Provider" Named Pipe Provider, error: -40. Could not open a connection to SQL Server. MS SQL Error 53.
