Named Pipes Provider, error: 40 - Could not open a connection To SQL Server

I am trying to setup a notification service sample (from Joel Webb's book) for SQL server 2000 and notification service 2.0.

When i run nscontrol create at the cmd prompt, i am getting the following error:

Notification Services failed to retrieve the SQL Server edition.

SqlServerError:
Source: .Net SqlClient Data Provider
Number: 53
State: 0
Class: 20
Server:
Message: 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)
Procedure:
Line Number: 0

Any help on how this could be resolved would be really appreciated.

Thanks,

Hi Nirmala -

Thanks for buying the book. I hope you find it useful!

As for your issues, you may want to double check the name of the server and SQL Server instance to make sure they are correct. You may also want to verify that the server does indeed allow remote connections and that it is using named pipes as a communication protocol.

HTH...

I tried all the suggested things but unfortunately still seeing the same errors. Any more thoughts?

Thanks,

|||In the description of the problem you mention SQL Server 2000 and SSNS v2.0. However, in the actual error message it references SSNS 2005.

SSNS v2.0 was developed using version 1.1 of the .net framework and will only work with SQL Server 2000. SSNS 2005 was developed with v2.0 of the .net framework and is only available for use with SQL Server 2005.

Could it be that you have mismatched versions? And that is what is causing the problems you are seeing?

Hi

I had a similar error in analysis project.

In my case I did not use the real servername as I had put an alias name for the server in my hosts file.

When I changed the server name in my datasource to reflect the real server name in stead of the alias name, I was able to deploy the project.

Named Pipes Provider, error: 40 - Could not open a connection

Ok,
I've spent a bunch of hours trying to figure out how to connect to SQL
Server 2005. I have MSDE 2005, IIS 6.0 and ASP.NET configured on my laptop.
I can run ASP.net code with no problem. I can access SQL Server from the
command line using osql with no problem.
But trying to access sql server 2005 from asp.net yields the following
message:
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)
Can someone help me with this? I have both tcp/ip and named pipes enabled.
--
ThanksCan you post your connection string?
specifying
Network=DBMSSOCN
in your connection string will cause it to use tcp instead of named pipes,
which is less error prone.
See here for more details:

Named Pipes Provider, error: 40 - Could not connect; Error 2

I have installed MSSQL 2005 successfuly, checked the services their are running I can connect to the

server with Intergrations Services ok. I get the following when I try to connect to the Database Engine

(provider: Named Pipes Provider, error: 40 - Could not
open a connection to SQL Server) (Microsoft SQL Server, Error: 2)

What file is SQL looking for (net helpmsg 2)?

Thanks for the help

Did you enable remote conenctions ? Check my website for the screencast which explains how to enable the Remote connections on your instance.

|||Would this be true for a standalone PC? I don't have SQL Server installed on a remote server.|||

For a standalone PC, you want to disable remote connections for TCP/IP and Named Pipes but you probably want to enable them locally (especially considering that you are trying to use named pipes here). So you should start SQL Server Configuration Manager, then go to "Protocols" then enable both TCP/IP and Named Pipes. To make sure that remote computers cannot connect to your machine -- go to SQL Server Surface Area Configuration -> Surface Area Configuration for Services and Connections ->Remote Connections and turn off remote connections.

That should do it,

Named Pipes Provider, error: 40 - AAAAAAAAAAAAAAARGH!

Hi,

I have been getting this error for about 6 hours now. I have read every article from google about it and absolutely none of the solutions work for me.

I am running Windows XP Home Edition

I downloaded and installed Visual Studio Web Developer Express about a week ago.

I downloaded SQL Server Express 2005 yesterday.

It installed fine.

I got my first error trying to add New Item->Sql Server Database only to find out the default instance SQLExpress was not working and i was running a different instance.

Anyway, I am trying to connect to sql server with the below code:

 SqlConnection myConnection =new SqlConnection("server=mycomp/mssqlserver;database=mydb;Trusted_Connection=yes"); SqlCommand myCommand =new SqlCommand("select category, title, article from articles where id=15");// + article + ");", myConnection); myConnection.Open();

Which give me the below error:

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)

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: 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)

Source Error:

Line 30: SqlCommand myCommand = new SqlCommand("select category, title, article from articles where id=15");// + article + ");", myConnection);Line 31:Line 32: myConnection.Open();Line 33: Line 34:

I have followed all the instructions online like enabling 445 firewall stuff, making sure i accept local and remote connection, enabling TCP/IP Named pipes and heaps of protocols ect but nothing works.

I am about to uninstall sql server and .net and call it quits.

This stupid server is too hard to configure.

If anyone could help me get it running it would be gretly appreciated however, this question seems to be asked all over the net and i have read gazzilions of threads with all kinds of answers but nothing works.

Thanks

Did you try to re-install SQL? and install it as default instance?

|||

Ok, I got your problem. You have to do some more configuration
Go to SQL Server - SQL Server Configuration Manager.
Check the protocols Named Pipes and TCP/IP should be enabled
then go to Client Protocols, and check Named Pipes and TCP/IP should be enabled

Please check it, I hope it works.
Let me know in case of any difficulties.

|||

Thanks guys.

As you can see in my first post i have tried all the common solutions like configuring the client protocols ect.

I think i will just reinstall and see how it goes.

Cheers

|||

Let us know how it turns out

Named Pipes Provider, error 40 Could not open a connection to SQL

Hi,
I have a big problem, I have a website in a Windows 2003 and SQL Server
2005, and the website usually goes weel, but some times and error appears,
the error is "Named Pipes Provider, error: 40 - Could not open a connection
to SQL Server".
There is not installed a firewall and TCP and Pipes connection are enabled.
Any ideas?
Thanks in advance,
Miguel
I have seen this before in SQL Servers that have been configured to support
N connections and no more. In this case, the named pipe is opened (the
Connection) but the server finds that the connection limit has been reached
so it closes the pipe at the server end. This confuses the connection pooler
who responds that the named pipe has failed and the connection could not be
opened after all.

Named Pipes Provider

Hi!

I tryed to make an silent mode install for SQL express edition, for example:

start/ wait setup.exe /qn ADDLOCAL=ALL SECURITYMODE=SQL SAPWD=***** SQLBROWSERAUTOSTART=1 DISABLENETWORKPROTOCOLS=0

When i run it from a .bat file it's ok but i'm using this command in a .ini file in some apllication.
It doesn't install all the SQL, i mean in services it appears only SQL Server VSS Writer.
I also get the error Named Pipes Provider. The application that i want to install gets installed but can't connect to server.
I really need some help.

Seems your server is not installed at all. If no server is running, you will see the Named Pipes Provider error. So, make your server is installed first. How do you initiate the setup from a .ini file?

Named Pipers Provider, error 40, ok from local, error to remote - help

Hi.
I am new to sql server so please bear with me.
Here is the problem.
I am using VWD express to connect to a sql server 2005 db on my local
machine. The site and the sql server are local and everything is fine.
No problems.
I have a sql server hosting plan to host the db. (my local is SQL
Server 2005 and the hosted is Sql Server 2000).
I use the LOCAL VWD website to access the HOSTED sql server and it
connects with no problem. I changed data in the remote version of the
db as a double-check that I am accessing the remote db and not the
local db.
When I go ahead and upload the web site to my web host, different from
the sql host (long story), I get this error (provider: Named Pipes
Provider, error: 40 - Could not open a connection to SQL Server).
Any ideas why this error is happening. My web host verifies that my
connection string is fine, and that if I can connect with my local
machine then there should be no problem and the problems is on the
hosting end.
Thanks in advance,
RanginaldOk. Problem solved. I was using a web host with multiple hosted
domains and I think I probably had some kind of IIS app directrory
problem. I moved the site to its own hosting and all was fine with no
changes needed.
Thanks anyway. Hope this tidbit helps someone.

to connect with TCP/IP (set Network Library=dbmssocn). Assuming that the SQL
connectivity components are properly installed on the web server and you can
ping the database server from the web server, I'd try a few things.
1. Find out the IP address and the TCP port that the SQL instance listens on.
2. Change the connection string to the IP address followed by a comma and
then the TCP port (e.g. set Server=169.12.35.51,5002). If this does not work,
you may have a problem with accessing the port. (if it's the default instance
using the default port, you don't need to test with the port number specified
explicitly).
3. Change the IP to the server name in the Server property of the connection
string, and try again. If this doesn't work, you may have a problem with
resolving the server to the IP address. Try the fully qualified domain name
instead.
If you can connect with TCP/IP, but not with names pipes, you may have a
problem with the ports used by the named pipes being blocked.

Named Pipe Provider/Linked Server Connection Error

Hello, everyone!

I'm currently having an issue with a linked server. Here's the surrounding information:

A) I have a clustered SQL Server 2005 Instance (A) and a SQL Server 2000 instance (B).

B) There is a linked server on A to B. When I set it up, I did run the fix to ensure A could talk to B (There was an issue with communication between 2005 and 2000 servers). It has been there since I installed A, and has worked fine.. Until last week.

C) This linked server uses static credentials to connect to B.

D) Named Pipes are enabled on both servers to listen to both connections on both A and B in cliconfg. So A has a named pipe listening for B, and B has a named pipe listening for A.

E) A has a view that looks at a table on B - It's a table view, very simple, just pulls in all the data from the table on B.

So, I go to do a select statement from the view, connected as a user other then 'sa'. I then get the error:

Named Pipes Provider: Could not open a connection to SQL Server Linked Server

Error Source: ncli Client (Paraphrasing, didn't copy that down, but it was the ODBC connector)

Well, that's odd. It's been working fine for months now..

I then go and connect as sa on A to query B. It works! Mind you, absolutely NO QUERY from A to B will run again until I run SOME kind of query has been run as sa on A.

Mind you, this is not a credential issue. Every user who connects to the linked server to B uses a stored credential that is DBO to the database on B. The same User Name and Password exists on both A and B.

Also of note, I check the activity monitor. There's a process that is "dormant" every time I run a query against the view. The details of this connection are:

sp_reset_connection;1

My question is, why is it resetting the connection on B when being queried from A? Why is it "all of a sudden" a problem? Are there any changes that coudl ahve been made that would cause this?

Any help with this confusing issue would be appreciated.

Thanks!

No one has any idea?

|||we found this to help us out: data source = servername,1433 (the port used), we noticed that when using an alias as the Linked Servername (not the actual servername) it failed, yet if the servername was the LS name it worked, so we added ',1433' to the data source and it cleared up our problem.

MySAP Business Suite ERROR: Table class INTTAB is not supported.

Hi there,

we collect data from SAP via the Data Provider for MySAP Business Suite.
Everything works fine for Standard objects like KNA1 etc. but if we try to read data from a custom table we get the following error:

Code Snippet

Fehler bei Get ZZEUSGRP_WA [SAP ZZEUSGRP_WA [1]]: Microsoft.Adapter.SAP.SAPManagedProviderException: Table class INTTAB is not supported.
bei Microsoft.Adapter.SAP.SAPSelectHandler.CheckResult(SAPTable returnTab)
bei Microsoft.Adapter.SAP.SAPSelectHandler.ExecuteSelect(SAPTable tabFields, SAPTable tabStruct_Tab....

The error message tells me not to use a specific table type. So far so good.
The question is: What would be the workaround? What should I tell the SAP team who cares for the data structures?

Thank you for your advice in advance
Fridtjof

OK, the reason for this problem is: The referenced SAP object is a view which is currently not supported by the connector.
(That doesn't really anser my question but nevertheless it is not a bug)

My SQL Provider

Hello to all,
I have a problem in connecting in a MySQL database. I can create some ODBC
connection, but I can't use it to manipulate data.
I like Know if Existe a MySQL Provider for SQL Server 2005 that alow me to
create connections and manipulate date withe this connections.
Thank you in advance.
It's not clear but I would guess you are trying to connect
from SQL Server and query MySQL?
First - what do you mean you can create an odbc connection
but can't manipulate data? Where did you create the
connection - linked server or what?
What errors did you get trying to do this? Can you execute
any selects?
