"An error has occured while establishing a connection to the server.
when connection 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)"
NB:
- on SQL Servers' Surface Area Configuration, Remote connections are set to "Local and Remote connnections" and "Using both TCP/IP and named pipes".

Hi, I had an old web application created during asp.net 1.1 and it have a connection problem with the sql server 2005 when it is mirgrated to a new webserver with dotnet framework 2.0 platform. I have enabled the remote access(TCP/IP and named pipes) in sql server 2005, did all the neccessary things, check whether the TCP/IP is enabled, named pipe is enabled... I created another web application using VS 2005. The database connection works perfectly well.This are the connectionString from the old web application.<appSettings> <add key="ConnectionString" value="Server=127.0.0.1;Database=somedb;User id=user; Password=somepassword; Trusted_Connection=False; POOLING=FALSE"/></appSettings> Thankyou in advance!

Hi there,
I got an approach like that:
1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc.
Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that?
The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2).
Thanks for the input!

Hi, Has somebody had a problem like this before? Exception Details: System.Data.SqlClient.SqlException:
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) That's part of the code: SqlConnection con; string sql; SqlCommand cmd; con=new SqlConnection("Data Source=elf/SQLEXPRESS;Initial Catalog=logos;Integrated Security=SSPI;"); sql="SELECT max(id_kandydat) from Kandydat"; con.Open(); cmd=new SqlCommand(sql,con); int id = Convert.ToInt32(cmd.ExecuteScalar()); con.Close(); SqlDataSource7.InsertCommand="INSERT INTO Kandydat_na_Kierunek(id_kandydat, id_kierunku, id_stan) VALUES ("+"'"+id+"'"+","+"'"+DropDownList1.SelectedValue+"'"+","+'1'+");"; I don't really get it. I'm nearly 100% sure that before some changes in my project this had worked perfectly. Does anybody have any idea how to make it work again? I would be very grateful for any help. And, yesy, I know it is quite common error, but proposed solution found didn't help.Regards,N.

tried to install SQL Server 2005 in a fresh installed Windows 2003 SP2. And this server is a workgroup member, not a member of a domain.
The services (Database service, integration service, reporting services and so on) work fines, but I could not connect to server
I checked the log, I found the following error,error :40-Could not connect to SQL Server(Microsoft SQL Server,Error-1231).
I never had this problem and this time, I really got the trouble and do not have solution.
Who have ever encounter this problem? Or someone can help me?
Thanks.

Hi,
I've created an "ASP.NET Web Application" project in Visual Studio and I want to simply open a connection to a database in SQL Server. All I have done is adding these 3 lines below without modifying any other generated codes by Visual Studio.(I've done this within code behind in Page_Load() not by <script> tag within HTML code)
public class WebForm1 : System.Web.UI.Page { private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here SqlConnection c = new SqlConnection(); c.ConnectionString = "workstation id=BABAK;integrated security=SSPI;initial catalog=db1;persist security info=False"; c.Open(); } ... }
But I get this error :
Server Error in '/projects/fortest/tDB2' Application.--------------------------------------------------------------------------------
Login failed for user 'BABAKASPNET'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'BABAKASPNET'.

What's wrong ?

I posted this on the Dotnetnuke forums but no answer for it, so since it is a SQL error I guess maybe someone here might know.
I installed the core forum that comes with the installation, the page runs great until I add the forum module.
I get this error:
A critical error has occurred.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)
The portal is in godaddy if this can help.
Thanks,
Erick

I have created a new aspx site on ‘server 1’ which connects to an sql server 200 on ‘server 2’ ‘Server 1’ is a test server and all works fine. I then move the site onto ‘server 3’ and receive the error below.
This must be a problem with ‘server 3’. I have installed .net version 2 on this server and there are currently no aspx sites running of this server. There must be smothering not configured right. There are other sites on the server that are talking to the SQL server.
Any help would be great.
Thanks

Hi Gurus,
In my code, I need to update the table on the linked server according to the XML input. A table variable is used to store the value from XML.
But the collation of the linked database doesn't match with the default collation used by the table variable, so the table join fails.
I am thinking about to open the connection to the linked server directly, and use the target database. So the table variable collation should be as same as the target database collation.
Is it possible to open the connection to the linked server in c# ?
Thanks and best regards,
Jennifer Zhao

After install Visual Studio 2005 (with SQL sever express) on recent Vista build, trying to connect to a local sse database file from Data Source Window (accessible from Data/Show data source window) gives this error:

OK
No issues if we install Visual Studio 2005 on WinXP or W2k3.
Is there any configuration we need to set on vista to allow sql connection?
Thanks,
Mei

Hi,
I am running XP Professional SP2. I have tried to install both SQL 2005 Developer (on this machine) and SQL 2005 Enterprise (on my other laptop), seemingly with success, but get the following error message when I try to connect to the local host using SSMS:

Hello All!
I'm getting the following error message below from SQL server error log, see below.
And the following error on the web browers:
"System.Data.SqlClient.SqlException: 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) "
I have see this link (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=192622&SiteID=1) and other links and done the changes they recommend, but it does not give any positive results.
I have also in the firewall added named pipes internal and external port 445.
I have also in RUN executed "cliconfg.exe" and enable the tcp ip port number 1433 and named pipes "sqlquery".
In the sql server configuration manager, have I enabled both tcp/ip and named pipes. The same in the server surface area configuration. I have also enabled remote access.
Still having the same problem??!!??
Iam out of ideas ...
Please need help, thanks in forehand!

This was originally posted in the SSIS Forum, but a member of the IS team suggested it be moved here. "Most recently I got this error (Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) so does this mean that SQL Server is still trying to use named pipes even if I only have TCP/IP enabled in SQL Server Configuration Manager?"
I'm having the same issue, and here's our scenario:
Installed SQL Server 2005 Developer Edition on a machine with WinXP SP2 and enabled remote connections over TCP/IP
Installed SQL Server 2005 Standard Edition on a machine with Win2003 SP1 (remote connections over TCP/IP enabled by default)
Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'Detach and Attach' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'SQL Management Objects' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
Reinstalled Standard Edition on the Win2003 SP1 machine
Checked all the settings on both machines several times, restarted services etc., and read every post I could find referencing the error.
Same error
Lost my last hair
Thanks in advance,
Steve

I start SQL Server Management Studio on my workstation and get the following message.

I had SQl Express version installed previously and everything worked. I could connect to one server running SQL Express and a different server running full up SQL 2005 enterprise version.
I uninstalled All SQL express programs and installed tools from SQL 2005 developer.
I have rebooted, started the program directly (not using a link of any kind) and all attempts fail. After dismissing the error msg the tool opens and I can run queries agains the DB but the database engines and related tables do not show.
My work station is Windows XP with SP2 installed.
I have googled the problem extensively and tried solutions found but none have solved the problem.
Any help greatly appreciated.

My configuration is: Vista Home Premium, SQL Server Express and I'm trying to access a database on an instance named AxisSQLServer in a C# application.
As a result of a previous post (SQL Network Interface, error 28), I have selected "Local and Remote, using TCP/IP only" in the Surface Area Configuration for Services and Connections.
SQL Server is started.
SQL Server Browser is started.
Both programs have been added as exceptions to the firewall (don't understand why I would need to do this since everything is on the same box).
Have turned off McAfee AV.
My connection string reads:
string connectionString = "Data Source=localhost;" +
"Initial Catalog=AxisSQL;Integrated Security=SSPI";
where AxisSQL is the database I'm trying to read.
I have looked at and followed numerous forums and blogs and always get the same error.

My connection string (to a remote instance of SQL Server Exress 2005) is exactly the same when the web files are located on my local machine or my remote machine, and while it works fine when I use the local web files, I get the following error when I use the remote files:
"Named Pipes Provider: Could not open a connection to SQL Server [53]"
As you can see, since it works from the local version, I've setup SQL to accept remote connections via TCP/IP and Named Pipes. I'm using IIS7 on the local, and IIS6 on the remote, in case that makes a difference. I have other sites setup the same way, which work fine.
Any thoughts?

Good day,
I am writing an application using VB.Net 2005 for the Windows CE 5.0 device and it is connecting to a SQL Server 2005 Mobile Edition Database.
The trouble I'm having is establishing a connection to a SQL Server Mobile database on the device.
Here is the code I am using:
Code Snippet
Public gConnectionString As String = "Data Source=Program FilesMobAppMobDB.sdf;Persist Security Info=False;"
Code Snippet
Imports System.Data.SqlServerCe
Public Class DBManager
Public Shared gSQLCEConnection As SqlCeConnection
Public Shared Function OpenDB() As Boolean
If gSQLCEConnection IsNot Nothing Then
Throw New InvalidOperationException("Connection already open.")
End If
gSQLCEConnection = New SqlCeConnection(gConnectionString)
Try
gSQLCEConnection.Open() 'Error occurs here
Return True
Catch ex As SqlCeException
MsgBox(ex.Message & vbCrLf & ex.HResult & vbCrLf & ex.NativeError & vbCrLf & ex.Source)
Return False
End Try
End Function
In the immediate window I recieve the following messages:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
I believe that the first few lines are caused by the icons/pictures that I have included with my app, but the SqlCeException line occurs when the connection to the .SDF file is trying to be established.
Here is the exception output:
Message: "" (Blank)
HResult: -2147024882
NativeError: 0
Source: SQL Server 2005 Mobile Edition ADO.NET Data Provider
Programs under Remove Programs on the PDA are:
Microsoft .NET CF 2.0 ENU-String R...
Microsoft .NET Compact Framework...
Microsoft SQL Client
Microsoft SQL Mobile 2005
Microsoft SQL Mobile 2005 [EN]
Microsoft SQL Server 2005 Compact...
Microsoft SQL Server 2005 Compact...
Microsoft SQL Server 2005 Compact...
Microsoft SQLCE 2.0
Microsoft SQLCE 2.0 Dev
Any ideas on what could be stopping this connection from being established? It was working before but all of a sudden just stopped. I have warm booted, cold booted, and rebuilt with no luck and also checked that SQL Query Analyzer is not running on the PDA and that the connection string is valid.
The call to OpenDB occurs in the form_load of the startup object.
Thanks in advance,
Leon

I am accessing SQL2005 with C# code using OleDbConnection.
A try and catch block catches the following error once a while between the Open() and Close() of the connection:
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.
Any hint would be greatly appreciated.
