I have an instance of SQL Server 2008 R2 on my local machine, and today, when I try to connect via Management Studio (as I used to do with no errors, using Windows Authentication), I get the following error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)
Any sugestions?
