SQL Express remote connections

SQL Express remote connections

  • Comments 45

Networking protocols are disabled by default in SQL Server Express. The error message you will get when trying to connect from SQL Native Client will look like this


“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 default settings SQL server does not allow remote connection. ( provider: Named Pipes Provider, error: 40 - could not open a connection to SQL server. )”


The solution to this is to enable remove connectivity on SQL Express; see the following link for info on how to do this.

  • Hello, I have the same problem as many of you have, I've followed various articles on how to set up the remote connections, but it still doesn't work, I can connect locally, but when it comes to remote connections it always gives me this error:

    HResult 0x2AF9, Level 16, State 1

    TCP Provider: No such host is known

    Can anyone help me?


  • I have a very similar problem as both of you as well!

    I have MS SQL 2005 Express and VWD and cannot get the login control to work due to an SQL error that reads:

    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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

    My server instance is SQLEXPRESS

    I have enabled TCP/IP and Named protocols, added firewall exceptions for sql server/browsing, and I just cannot get past this error.  It is on a hosted site so Im trying to remote into the site and log in on my own asp login control, but the control isx supposed to verify against the db but it doesn't, it just gives the above error.  It worked fine when it was local, but not when transfered to the hosted envrionment.  

    This is how I know it's not an asp issue, but an sql remoting problem.  

    Any direction would be greatly appreciated as Im an inexperience db configurer.  I have been googling this problem for about 3 weeks and everything people suggest is not working.

  • davidbotero: It's likely that the problem is not a SQL Server problem. Have you tried pinging the remote machine? If you are unable to get a response from it, then it sounds like there is a problem elsewhere.

  • Hello all,

    I am having a similar problem. I am creating a simple application to alter information in a database. I have created the application in Microsoft Visual Basic 2005 Express Edition and am trying to connect to a local database created using SQL Server Management Studio within SQL Server 2005. When I go through the Add New Data Source wizard in MVB 2005 Express and browse to the database I want to connect to I get an error 26. I don't understand what to do. Everything is local on one machine. Under the advanced tab it won't allow me to change the Data Source to anything but .\ServerName.

    Please Help

  • Hi all,

    I need to know how to connect to a remote sql server using a C# window application. Let me make, my issue more clear. I want to develop a application in C#, that can connect to any SQL server whether its local or remote using valid crendentials. I saw many appliations, that search automatically into LAN for SQL Server instances. But I want user to put either server name or ip address instead of searching for insatnces automatically.

    Please help me out. if there is any online resource regarding this, please put it in reply

    Thanks and regards
