SQL Server (Microsoft SQL Server, Error: XXX) ★★★★★★★★★★★★★★★ SQL Server ConnectivityMay 16, 20077 0 0 0 This error message is the most frequent error message when connecting to SQL Server. You see this 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/ error message when you use SqlClient. In SNAC, the error message is slightly differently as follows: C:>osql -E -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 sql server Pipe Provider, the issue does 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 could not open error message. xxx is Windows error code 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
