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: 1311)For help, click:BUTTONS: OKI had previously been able to connect without issues, but there were some changes made to the server (it was turned into a domain controller), and it is now refusing to work as I had assumed it ought.I've tried restarting the SQL Server Browser instance and I've already checked the firewall settings. However I won't rule out having missed something.I'm stymied and the database needs to be up 20 minutes ago.How do fix this problem? When SQL Server was installed, it was most likely set to run as a network service or a local service account, which will not work properly on a domain controller. Whilst SQL Server can run on a domain controller (not recommended for security reasons), it should only be installed after it has been promoted.

Likewise, demoting a machine will result in similar issues with SQL Server installed beforehand. I would suggest making a backup of your databases, then uninstalling SQL Server entirely, installing a fresh copy of SQL Server, and finally restoring your databases. That way, when you install SQL Server this time, it will detect the different user / security environment and offer only those security options that will actually work on a domain controller.Here is a link to the. I just wanted to help someone out that might be ready to pull their hair out over this error at top of this page and others like it. Do the SQL Server error logs indicate it's properly listening on the TCP port? When you run a netstat -ano, do you see the TCP port open and with a status of listening? Does the PID match up with sqlservr.exe?Since it's a named instance, the SQL Browser service will need to talk on the network.

That means udp/1434 should be opened up on the firewall, if it is blocked. If you see that the SQL Server Express instance is listening on the port, try connecting via servername,TCP port. For instance, if the instance is listening on 2601, try Server1,2601. If that works, then it's likely the SQL Browser service is being blocked. On that note, make sure that the port SQL Server is listening on is permitted in the firewall. And you'll probably want to make that a static port if it's currently set to dynamic.
