ODBC drivers error

Everything was working fine on my website until last night we started getting the following error message while viewing to see the pages. Website is running on asp and sql server.

"Microsoft OLE DB Provider for ODBC Driverserror '80004005'[Microsoft][ODBC SQL Server Driver][Named Pipes]SQL Server does not exist or access denied.

reports/penaltyrankingreport_web.asp, line 19 "



I checked the line in my code and error is occuring at the line when the code is opening the recordset..

"objconn.open"

i already referred the following article on microsoft but not exactly sure in which direction to troubleshoot because i didn't make any changes to code, servername, database properties.

Please let me know your feedback.

Sounds like the connection to the database cannot be made - possible physical connection lost or database has gone down. Where is the database hosted? Different server to the web server?

Database went down before 15 days when we did restore and then it started working again. webSite also started working fine with the new updated restored database. Only since yesterday out of nowhere we are seeing this error message everywhere on our website.
