We just changed the dev environment to sqlagent. From then we were unable to see the reports on the report server because:
An error has occurred during report processing.
Cannot create a connection to data source 'IHRSDataSource'.

this error is cropping up.
To Resolve this issue, we checked the Surface Area Configuration and also checked the Reporting Service Configuration . There seem to be no problem and everything looks ok.

I am new to dotnet. I tried connecting to the database MS SQL Server 2000. I gave the code like, the one below, in form load event,
SqlDataReader dr = null;
SqlConnection myConnection = new SqlConnection("Data Source=IP;Initial Catalog=name;User Id=uid;Password=pwd;");
myConnection.Open();
myConnection.Close();
But I could not connect. The error message highlights the line myConnection.Open() and displays the error

It tries connecting to SQL Server 2005. There is no SQL Server 2005 in that system. There is only SQL Server 2000.
I have the aspx code in my local system and the database in another machine.
Could Someone please help me out in solving this problem.
I realised this has been done to death, and so much information out there but I am still in a quandry.
I have had to rebuild my computer.
This is what I did
XP machine using SQL Server 2005 Standard Edition using Windows Authentication NZ6(MSSQLSERVER)
straight default install all the way
unfortunately when ready to run reports from my instance(computer) I received the error as in provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
thought I had it all okayed but obviously something not right
so ended up unistalling then - did the following:
Load SQL Server from disc1 and start install failed on alter Counter Registry key error fixed this from KB article (known error that can happen) restarted Went to Windows Update check IIS is installed - tick is on - IIS - admin tools - make sure asp2 is associated - yes ok Then back to install sql server - there is no instance set up yet Disk 2 and setup .exe
All ok on Reporting Services, Analysis etc.
But once again all seems fine but still getting the error:
connection is all fine in Management Studio - eg I can see tables etc connection is all fine in Business Intelligence - eg I can preview my reports I then can deploy up to - NZ6 open NZ6 eports report is there fine - but just errors
some simple little tick that I have not done!!
I seem to have checked and rechecked everything and obviously doing another re-install does not seem a logical step from here. I will continue to check but if someone jump in and advise please would be great.
I am creating a web site using Visual Studio 2008 & trying to connect to database on SQL Server 2000. My test connection is successful but while debugging the page I am getting this error : " provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server "
Solutions recommended for this were start running the SQL browser instance and enable Namespipes in Sqlserver configuration manager.Did both.. but nothing worked.
I made a Web page, and it works perfect on my local machine, everything is OK, until I uloaded page to the server, it reports this error:

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! Nikita

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
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.

I have merge replication configured over VPN and the replication is failing to connect to the subscriber through Named pipes with the error Named Pipes Provider, error: 40 - Could not open a connection to SQL Server ......
Actually , I am having issues with Named pipes connection from publisher to subcriber. I have enabled the protocols and also enabled the remote connections using both tcp/ip and named pipes. I have created the client network alias using named pipes
Also, due to security reasons only few ports have been released on the subscriber. Please provide me some information on the following. 1) Does any port specifically be released for listening on named pipes? i am able to connect using tcpip with out any issues as 1433 has been released. 2) How to configure the replciation to use tcpip and not named pipes (guess by default it will use named pipes)?

Hi, My .NET 2005 application is on a server outsite company's domain. SQL server is in domain and port for sql server is open. TCP/IP is set for remote connection in SQL Server. Connection string in .config is <add name="X_Conn" connectionString="Data Source=XXX;Initial Catalog=XXX;User ID=XX; Password=XXX;" providerName="System.Data.SqlClient"/> I receive the error below: 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) thanks a lot in advance!
We experience the 40 error when our Asp.net code runs under IIS and uses named pipes to a sql server 2005 named instance.
We've tried all suggestions found on blogs and KB articles such as making sure the named pipes protocol is enabled, making sure the Browser service is started, making sure Allow Remote Connections is enabled, making sure we're not using Asp.Net 2.0 membership providers, and the list goes on and on.
We boiled it down to a simple test scenario. We open a SqlConnection to the sql 2005 box in the code with the intention of binding a datareader to a gridview, but it never gets that far because the connection.Open() fails.
If we run this test application as a virtual directory in IIS and Asp.Net 2.0, the connection.Open() fails.
If we run this test application from Visual Studio .Net using Cassini (PWS), the connection.Open() succeeds and binds to the gridview.
What could be causing the connection to fail under IIS but succeed under Cassini? We've tried setting IIS to run as a domain user and with digest authentication enabled. That made no difference.
I have a web application developed in VS.NET 2005 [using C# as code behind]; and it uses SQL Server 2000 Enterprise edition as backend. The application runs fine, though it gives an error on IRREGULAR intervals on SQL data requests. Error Details: 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)
My problem is this: 1) Why does it show an error of SQL 2005, while I use SQL 2000. SQL 2005 is not even installed on the server, though VS.NET 2005 is installed. 2) The error comes only at irregular intervals. Users are able to login properly otherwise. 3) Application starts working again if we do either of the following: (a) Restart IIS (b) Restart application pool (c) Restart server. 4) Named pipes and TCP/IP are added to the "Network Configuration" of the SQL server 2000. 5) Error does not come on any specific page; or any specific code; or at any specific time. 6) We do not have any background service or any other activity happening on the server; and the server hosts only this application, within a single virtual root.
Any thoughts on why is this happening, and how to resolve this?

Hi,I have SQL Server Express Edition. I tried working out some ASP.NET Labs in my local system. Here is the link of the Virtual Lab which I tried. http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032286906&EventCategory=3&culture=en-US&CountryCode=USI recieve this error in my local system. 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 tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.
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.
I'm encountering an issue with "Named Pipes Provider, error: 40 windows" and am having problems determining how to fix it due to the environment I'm using. I have two SQL Servers installed on two separate Win2K3 Server boxes, one is SQL Server 2000 and the other is SQL Server 2005. The SQL Server 2000 contains the actual application data. The 2005 database is used only for Reporting Services. I've set up the reports on SSRS such that their datasources hit the 2000 server. This is using SQL Server authentication.
When testing the reports via SSRS (in Visual Studio 2005), the connection to the data works and the reports are generated fine. When I deploy them to the reporting server and launch IE to test locally (still on the 2005 box), I get this "Named Pipes Provider, error 40" issue. I made sure that Named Pipes and TCP were enabled and the port set at 1433 (to match that on the 2000 box).
Now I changed the datasource's authentication from SQL Server to Windows authentication. I tested this in SSRS and this works too. When I redeployed the reports with this authentication change, testing the reports via IE locally (on the 2005 box) worked (using Administrator login). Great. Now when I open IE on an external box, i.e. on the 2000 box, and try to test the reports using that server's Administrator login, I get this same error 40 issue. I've been through a few threads describing the error 40, fiddling around with the SQL Server configuration as well as SSRS, to no avail. I have a feeling this error 40 issue has to due with permissions/authentication between the SQL Server boxes but I can't really be sure. Anyone have any ideas on how to troubleshoot my situation. Thanks.
