When starting the application, everything goes well and a query is done to the server with no problems.
Once I click on a link that requires another connection to the Sql Server 2008 express R2, I get an error :
Une erreur liée au réseau ou spécifique à l'instance s'est produite lors de l'établissement d'une connexion à SQL Server. Le serveur est introuvable ou n'est pas accessible. Vérifiez que le nom de l'instance est correct et que SQL Server est configuré pour autoriser les connexions distantes. (provider: Named Pipes Provider, error: 40 - Impossible d'ouvrir une connexion à SQL Server)
The problem does not happens on the server : www.jbusinesses.com
Any one can help ?
I tried almost everything and everything seems to be ok since the first cinnection seems to be good, its only on a second connection the problem shows itself...
Thank you !
This is a common error when you can't reach your sql database server.
The the server name and instance in the second connection string.
Test if you can connect to that server from SqlServer management studio.
Also check if a firewall is blocking connections to that particular sql server.

I'm using SQL Server 2016 with SharePoint 2013. I'm trying to access to SharePoint List.
I use the OData Source in my Package. The connection works succefully and I can preview (with the Preview button) data from the list.
But, when I try to execute it got an error :
Error: La connexion « Connexion » est introuvable. Vérifiez que le gestionnaire de connexions renferme une connexion de ce nom.
In English :
The connection "connexion" is not found. Check if the connections managers has a connection with this name.
I have no connection named "connexion" in my package.
Do you have any ideas on this error please ?
I've build a simple package that extract data from an OData source.
It work with DTExec 12 (SQL Server 2014) but when I deploy to an SQL Server 2016 (DTExec 13) I got a weird error in french :
La connexion « Connexion » est introuvable. Vérifier que le gestionnaire de connexions renferme une connexion de ce nom.
Lousy translate in English it mean :
The connection "connexion" is not found. Check if the connections managers has a connection with this name.
I have no connection named connexion in my package.
Do you have any ideas how I could investigate this error ? How can I look at the available connections in the connection managers ?
I feel like there is no OData connector installed for SQL Server 2016 but there is an old one that was installed with SQL Server 2014 because DTExec 12 work on the same server with the same package.
I've been trying to connect with SQL Server 2008 but I couldn't, and I'm getting the error below. It says that : I have to check if the TCP port is blocked with a firewall... well, no it's not !
what should I do ???

problem resolved ,
Talend and SQL server are in the same machine so...
how I did it: on Sql server
1 - server type : database engine
2- server name : 127.0.0.1
3- Authentication : Sql Server authentication
4- login : sa
5- password : ***** (any password you want )
then I went to Talend:
I did put the same specifications ( specially the pass and login name)
The connection may not work even if firewall is allowing the port traffic but the SQL server itself is not enabled for TCP/IP protocol.
Are able to connect to SQL server using other client tools using TCP/IP protocol? use SQL server configuration Manager to "Enable" the TCP/IP access.
I have an issue with the execution of an SSIS Package within the SQL Server Agent.
Context :
I deployed a package into the Integrated Services Catalog : http://i.stack.imgur.com/m9Y9c.png I have not difficult to execute this package manually.
Problem :
When I try to execute this package within a job into the SQL Server Agent, I have an error : "Login failed. The login is from an untrusted domain and cannot be used with Windows authentication."
Exécuté en tant qu'utilisateur : NT Service\SQLSERVERAGENT. Utilitaire d'exécution de package Microsoft (R) SQL Server Version 11.0.5058.0 for 64-bit
Échec de l'exécution du package serveur IS en raison de l'erreur 0x80131904. Serveur : OPP41****** Chemin du package : \SSISDB\automates\automate_PIT_pilotage\recuperation_cmd_a_traiter.dtsx
ID de référence environnementale : NULL. Description : Échec de la connexion. La connexion provient d'un domaine non approuvé et ne peut pas être utilisée avec l'authentification Windows. Source : .Net SqlClient Data Provider
The owner of the job is my AD account.
This is how the step is configured : http://i.stack.imgur.com/QrJf9.png
The SQL Server Agent service is running through the "NT Service\SQLSERVERAGENT" account.
Thank you very much by advance, I'm going crazy !
Create credentials: Security -> Credentials
Create a proxy account: SQL Server Agent -> Proxies -> SSIS Package Execution
Set SSIS package to run as proxy account.
Take a look at article.
I had found that my Job was executing against a DNS name and not the SQL Server Name. So check your SQL server name : select ##servername and make sure you use this name in referring to the SQL server where the catalog is located and not some or other DNS name. I have found that it will also succeed using the DNS name to call the packaged from a different SQL server, but if the job runs on the local SQL server calling a package on the same SQL server then the server name must refer to the value in ##Servername.
The instance is running, but I still cannot connect, I get this error:

Any suggestions on what can be going wrong? Why doesn't this thing connect? :S
How do I find the instance NAME of a server? Why doesn't this work?
You need to enable the correct protocol(s) in your SQL Server Configuration Manager.
It is the second option in the screenshot you provided ("SQL Server Network Configuration").
You need to enable the protocols you need (all of them to make sure?) and then you need to restart the SQLEXPRESS service.
I don't speak whatever language that error message is in, but I'm guessing that it's similar to one that I've seen in a language that I do know. I think it's saying that the target machine may not be configured for remote connections. Whenever I see that, there's either a firewall between the host and client, the specific instance is down, or there is a problem with the SQL browser. As a test, can you telnet to the port that the SQL server is configured to run on?
Ben Thul is correct. You are getting this problem because the SQL Browser service is stopped.
By default (when using the full version of SQL Server but not SQL Express), SQL Server starts up and listens for connections on TCP port 1433. When you connect from SQL Management Studio (or your application) and don't specify a port, it tries to connect using 1433.
However - this is different for SQL Server Express (and other named instances of SQL Server). These start on a dynamic port and rely on the SQL Browser Service (UDP/1434) to provide the mapping between instance name and port.
So, in your example - you try and connect to ServerName\SQLEXPRESS. As it's not the default instance a connection is attempted to the SQL Browser service, which would then respond with the dynamic port of SQL Express (say port 12345). Finally, your SQL client will connect to ServerName port 12345 and will find your named instance.
In short - enable the browser service!
