SQL Express remote connections
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.

I'm having a problem registering a program that has MSDE(sql 2000) embedded in software after entering the CD key I get the following message:
"An error occurred attempting to register your copy of Encompass. The underlying connection was closed: Unable to connect to remote server."
Can you help? I think I've done everything I can and noone else has a clue.Anonymous

This error message is not thrown by SQL Server network layer. Rather it comes from .Net Framework Networking layer. My best guess is that you don't have network connectivity to Encompass online registration center. You can contact Encompass or find solution of .NET netowrking issue on http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=40&SiteID=1.Anonymous

Hi i have the following error.
kindly give some suggesion
'ROW_NUMBER' is not a recognized function name.
No rows affected.
(0 row(s) returned)Anonymous
April 10, 2006
ROW_NUMBER is a function that is only supported in SQL 2005, verify that your database is SQL 2005. For SQL 2000 you can use RANK function to get similar results, see:

What's else for Enterprise Edition? When the SQL Server 2005 setup completely, it did not ask for me like one I did that it's needed to fill Instance_name, Database_name etc.. It just done without any announcement. My TCP/IP was on PC, sure, including firewall option enabled. But I did not connect with the right named host_name. Checked registry with HKEY_LOCAL_MACHINEMICROSOFTMS_SQLSERVER, I did not found any key named as Instance. How do I solve it now? Thank you very much!Anonymous

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? ThanxAnonymous

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.Anonymous

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. HTH -Tres LondonAnonymous

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 HelpAnonymous

This web page has a list of many different variations of valid connection strings, depending on what you want to do. Remember, "don't miss the server name syntax ServernameSQLEXPRESS where you substitute Servername with the name of the computer where the SQL Server 2005 Express installation resides." http://connectionstrings.com/?carrier=sqlserver2005Anonymous

Although you need () for (local), you don't need it for IP address. i.e. you should use -- Data Source=192.168.2.1--. If you still see problem, Please post a question on our forum and provide more details about how it fails. http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=87&SiteID=1 Thanks. XinweiAnonymous

Hi Mohamed, SMO provides a .NET interface to many SQL management functions, including the ability to enable remote connections.
