describe connection problems according to different client stack: SNAC/MDAC/SQLClient. Thus, there are 3 parts for this topic. sql server error 17 First Part – Troubleshoot SNAC connect to SQL Server 2005 Second Part - Troubleshoot MDAC connect to SQL Server 2005 Third Part – Troubleshoot SqlClient connect to https://support.microsoft.com/en-us/kb/955638 SQL Server 2005 Before start, it is very important to identify which client connected to Server and failed. Here, I list out follow key terminology in Sql Server Connection. SNAC - A new data access technology that is new in SQL Server 2005, and is a stand alone data access application programming interface https://blogs.msdn.microsoft.com/sql_protocols/2005/10/21/sql-server-2005-connectivity-issue-troubleshoot-part-i/ that is used for both ODBC and OLEDB. MDAC - Microsoft Data Access Component contains core data access components, such as OLEDB provider and ODBC provider. SqlClient - Access data from within a CLR database object by using the .NET Framework Data Provider for SQL Server. Protocol Prefix: explicitly specify which protocol you want to use to make connection. Supported protocol prefix in Sql Server 2005 includes: “lpc:”, “np:”, “tcp:”, “via:” Last connect cache – contains the fully resolved/specified connection strings for the instances that were successfully connected to. Part I – Connection Fail when SNAC connects to Sql Server 2005 Use osql.exe to simulate the connection string in your application and quick troubleshoot if your application uses ODBC provider and use sqlcmd.exe for OLEDB provider. They are located in %SYSTEMDRIVE%Program FilesMicrosoft Sql Server90toolsbinn.

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. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 1326)I eventually found the resolution to this error on this blog itself; so I was saved from hunting for the solution. 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.
