SERVER - FIX : ERROR : (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: ) May 21, 2009Pinal DaveSQL, SQL Server, SQL Tips and Tricks616 commentsRegular readers of my blog are aware of the fact that I have written about this subject umpteen times earlier, and every time I have spoken about a new issue related to it. Few days ago, I had redone my local home network. I have LAN setup with wireless router connected with my four computers, two mobile devices, one printer and one VOIP solution. I had also formatted my primary computer and clean installed SQL Server 2008 into it. Yesterday, incidentally, I was sitting in my yard trying to connect SQL Server located in home office and suddenly I stumbled upon the following error. Finding the solution was the most infuriating part as it consumed my precious 10 minutes.Let us look at few of the common errors received:An error has occurred while establishing a connection to the server.(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 5)An error has occurred while establishing a connection to the server.

I am sure there are a number of developers who had previously fixed this error while installing SQL Server 2008 or SQL Server 2005 but in due course forgot the right solution to this error. This is just a quick refresher. Make sure to bookmark this as you never know when you would need this solution.Let us check into the steps to resolve this error.1) SQL Server should be up and running. Go to All Programs >> Microsoft SQL Server 2008 >> Configuration Tools >> SQL Server Configuration Manager >> SQL Server Services, and check if SQL Server service status is "Running".In addition, ensure that your remote server is in the same network. Run "sqlcmd -L" in your command prompt to ascertain if your server is included in your network list. You can even find tutorial for the same here SQL SERVER - Find All Servers From Local Network - Using sqlcmd - Detect Installed SQL Server on Network.I have confronted numerous situations when these nerve-wracking errors crop up, and most of the time when I try to troubleshoot I notice that SQL Server services are neither running nor in
