Ms Sql Server Error 1326
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.

An invalid username or password is not what the error is telling you at all, that's a completely different error. –Sean Aug 5 '13 at 14:32 Try this article, it goes through pretty much all the steps you will need to troubleshoot your connectivity problems: social.technet.microsoft.com/wiki/contents/articles/… –Sean Aug 5 '13 at 14:33 1 See my answer here with my screen shot if you received this error with SQL Server {version} Express, when setting it up for the first time.

SQL Server (Microsoft SQL Server, Error: XXX) ★★★★★★★★★★★★★★★ SQL Server ConnectivityMay 16, 20077 Share 0 0 This error message is the most frequent error message when connecting to SQL Server. You see this error message when https://blogs.msdn.microsoft.com/sql_protocols/2007/05/16/named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server-microsoft-sql-server-error-xxx/ you use SqlClient. In SNAC, the error message is slightly differently as follows: C:>osql -E https://social.msdn.microsoft.com/Forums/sqlserver/en-US/9e3bcf70-7d47-4ac4-a29f-b61a3bc173a4/error-1326-logon-failure-when-attempting-to-backup-to-remote-server?forum=sqlsecurity -Syourserver[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server [xxx].[SQL Native Client]Login timeout expired Basically, this error message just tell you that the client cannot make a connection to the server. It's equvalent to "SQL Server does not exist or access denied" in MDAC. Although the error message say about Named Pipe Provider, the issue does ms sql not have to be NP related. The reason is that, by default, the client stack try TCP and NP in order. If the connection attempt could not success with any of them, then NP is the last protocol tried and this is the error message to present to users. When users see this error message, sometimes xxx is omitted. But actually, xxx is the most important part of this error message. xxx is Windows error code ms sql server and it gives customer hints about why the connection fails. Here are some error code users often see. I also explain the root cause and possible solutions here. 1) xxx=53winerr 53 means "The network path was not found". If you got this message, it means the client stack cannot find the target machine. Here are possible reasons for this failure, a) typo in the server name, or using "/" rather than "" between server name and instance name, e.g. "myserver/myinst" is not correct. b) name resolution to the server name is not correct, "ping -a yourserver" would tell if that's the casec) The server machine is firewall'ed and file sharing is not in the exception list. You need put "File and Printer Sharing" in exception. 2) xxx = 1326winerr 1326 means "Logon failure: unknown user name or bad password". When you get this error code, it means a) the client stack is able to reach the target machine, and b) the service account of the client application does not have enough credential to make a NP session to the server. NP is based on SMB (file sharing). The logon failure message represented by winerr 1326 is from SMB layer, not SQL Server. You need to make sure you can make a file sharing to the server machine with the same service account.If you cannot ma

However, if I open an cmd window and execute the move command from DOS, it will successfully move. There is a development server on the domain as well (devserver) using domain\sqlagent to run the service accounts, and I can successfully backup databases from dev to prod, dev to backup, backup to dev, backup to prod, prod to dev, but NOT prod to backup Finally, if I create a maintenance plan in SSMS, I cannot create a connection to the backup server (error reads the connection may not be configured correctly or you may not have the right permissions on this connection) The backup server was changed to a different domain (domain2) before I arrived here, but has been switched back n
