A network-related or instance-specific error occurred while establishing a connection to SQL Server RRS feed


  • The error you mention in the subject is both very general and quite common.  It basically means the SQL Server specified in the connection string cannot be reached.  Common causes range from the SQL Server service is not started, a typo in the server name, firewall blocking port 1433, the SQL Server not being configured to allow report connections, etc.

    I pasted this error text into the search forum questions box on this page and got over 300,000 hits.  It is likely that one of the causes in those answered questions will help you identify your problem.  If not, provide more details in the body of your question.  Not much to go on here.
