I had no problem with my sql server and management studio yesterday, but today it does not connect and show me this 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)
The only change I had made is changing windows user password, and I connect to sql using windows authentication what shoul i do to fix it?
