Can't Access Remote Sql Server If Disable Named Pipes

Dec 20, 2006

Hi,

I have windows 2003 (SP1) server with sql server 2000 (SP3) .

In the server network utility, I have enables only TCP/IP protocol and disabled the Named pipe protocol.

Now if I try to connect to the sql server from a remote machine, I get the message saying "unable to connect either server does not exist or ......".

I have configured the firewall to allow communication on TCP port 1433. It didn't help. I tried to disable the firewall completely, still it didn't work.

It works only if I enable Named pipe in the server's server network utility.

SQL Server 2000 / Named Pipes Error

Oct 3, 2000

I have a simple ASP page calling a COM+ function. The COM+ function is attempting to execute a stored proc on a SQL Server 2000 database. I am getting the following error:

Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC SQL Server Driver][Named Pipes]Specified SQL server not found.

The connection string I am using looks as follows:

driver={SQL Server};server=10.10.1.60;database=eSystem;uid=sa; pwd=;

- I have Named Pipes *disabled* on the SQL Server machine (at 10.10.1.60).
- As you can see, the connection string contains an IP Address and not the name of the SQL machine
- The server running the ASP page can ping the server sitting at 10.10.1.60
- The eSystem database does exist on the SQL machine sitting at 10.10.1.60

I suspect my error has to do with Named Pipes being used and I don't want to use Named Pipes. Could someone help me?

Thanks very much.

.NET 2.0/SQL 2000 Named Pipes Provider, Error: 40

Oct 3, 2007

 I have an app that I've written in .NET 2.0 using SQL 2000 as the back end. It works fine in development but when I move it out to our QA server I get the following 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) One of the odd things I notice is that the error message references SQL Server 2005 when that's not installed on our QA box, only SQL 2000 is on it. I've checked the server and TCP/IP and Named Pipes are enabled. Here is my connection string<add name="myConnectionString" connectionString="Data Source=(local);Integrated Security=false;Initial Catalog=TestDatabase;User Id=myUsername;Password=myPassword;" providerName="System.Data.SqlClient"/>There's at least one other .NET 2.0 application running on this server that accesses the database so I know that it can work! However, have access to the source code for that application so it's not any help with my troubleshooting. Any thoughts or ideas?

Need To Configure SQL Server For TCP/IP & Named Pipes

Feb 23, 1999

I have a question. When my SQL server was originally configured, it was only setup to use named pipes. Now I am needing to setup a P&M server (through Site Server 3.0), but I must have my SQL server to accept tcp/ip network connections. I don't know how to enable named pipes & tcp/ip. Any help would be greatly appreciated.

Is SQL Server 2005 Still Using Named Pipes ?

Dec 21, 2005

I keep getting errors.  It all started when I enabled named pipes on my SQL Server 2005 server.  Ever since then I've had connection problems up the butt.

Most recently I got this error 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?

Error:

TITLE: Connect to Server
------------------------------

Cannot connect to BG-SQL2005.

------------------------------
ADDITIONAL INFORMATION:

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) (Microsoft SQL Server, Error: 2)

OK

I get this when I try to connect to my DB period and I know the users are setup correctly, even tried both Windows Authentification and SQL authentification, no luck.  It was working happily for a few days it seemed before I enabled named pipes in the SQL Server Configuration Manager.

SQL Server Not Found When Named Pipes Net-Lib Selected

Aug 7, 1999

We had a crash of SQL server this week, everything came up fine, with the exception, SQL EM would no longer connect to SQL Server via named Pipes Library. SQL Server [DB-Library] Not found or Server does not exist.

Client Applications are able access the DB, ISQL /w acesses and runs SP's fine
DBCC CHECKDB returned no errors. I have to Reporting funtions that utilze Crystal Reports to connect to the DB. I am unable to do that n=now. This really is causing major problems. Any assistance would be appreciated.

I have already tryed Client Config. and adding the TCP/IP in the Advanced Tab wih Named pipes identified as "." and "(local)" [without quotes]. this did not work either.

If I have a corrupt Dll, can I reload it, or do I need to reload SQL Server, and rebuild databases from Datadumps?

Irregular Error In SQL 2000-Named Pipes Provider, Error: 40, Could Not Establish Connection

Apr 10, 2007

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?

Named Pipes Provider, Error: 40 - Could Not Open A Connection To SQL Server

Dec 5, 2007

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!

Named Pipes Provider, Error: 40 - Could Not Open A Connection To SQL Server

Jan 6, 2006

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

Named Pipes Provider, Error 40 - Could Not Open A Connection To SQL Server

Dec 5, 2007

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.

SSRS To Separate SQL Server Named Pipes Provider, Error: 40

May 2, 2008

Hi,

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.

SQL Server Admin 2014 :: How To Configure Named Pipes Protocol Correctly

Oct 5, 2015

I've been reading about the protocols and i've been trying to connect to my SQL SERVER using each one of the protocols, but i think I'm missing something, i dont have any problems using Shared Memory and TCP protocols, but I'm not pretty sure how to connect to my remote SQL SERVER using NAMED PIPES protocols. The books On Line of Microsoft refer that you can connect using this protocol using the next syntax: Connecting to a default instance by specifying a named pipe name:

APPHOSTpipeunitapp

Connecting to a named instance by specifying a named pipe name:

APPHOSTpipeMSSQL$SQLEXPRESSSQLquery

Connecting to default instance by name, forcing a named pipes connection:

np:APPHOST

Connecting to named instance by name, forcing a named pipes connection:

np:APPHOSTSQLEXPRESS

But I can't connect to my remote SQL SERVER, if i try the same with my local SQL SERVER i don't have any problems. I've been reading the articles so many times searching something about Named Pipes is only for local connections, but Microsoft say that it's posible to connect to a remote SQL SERVER, but i don't know how to do that. The firewall is disabled, I changed the APPHOST in the above syntax for the IP address of my SQL SERVER but it didn't work..

SQL Server 2005 - Reporting Services Data Sources Named Pipes VS TCP/IP

Feb 28, 2007

Can anyone shed light on why I cannot get away from named pipes in my SQL2005 Reporting Services Data Sources? Can it not just use TCP/IP? My configuration uses two servers, one in which the reportserver is setup on, and another which hosts the database that is reported against. We are trying to avoid having to open up named pipes on the server that stores the data.

Any help would be appreciated.



An error has occurred during report processing.


Cannot create a connection to data source 'wc_datasource'.



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)

Named Pipes Provider: Could Not Open A Connection To SQL Server [53], But Only On The Remote, Not The Local

Jun 18, 2007

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?

Merge Replication Failing With Named Pipes Provider, Error: 40 - Could Not Open A Connection To SQL Server

Sep 28, 2007



Hi,

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)?

Named Pipes Vs Tcp/ip

Oct 20, 1999

I am trying to run a sql script that was written by a third party to set up the tables and stored procedures of a 6.5 database. The script crashes
about half way through. The error looks like this...

The vendor said that I needed to change the client configuration to tcp/ip sockets instead of the named pipes that I was using. When I change
this setting I can no longer connect to the server through enterprise manager. The error message is...

I am not sure if the db-library is not set up correctly for the server or why it will not connect through the tcp/ip socket. I ran the ping command
from the command line and it returns a valid connection to the server. This doesn't make a lot of sense to me.

Does anyone have any experience with this problem or suggestions of something to try to fix this problem. Any ideas would be great. Thanks.

SQL Using Named Pipes Not TCP/IP

All - I have 2 SQL2K clusters, both have local applications and replication. The first cluster uses TCP/IP for all its connections when looking at SQL Management processes.

In your experience and all things being equal, is connectivity using named pipes faster, slower, or the same as tcp/ip?

How would one go about adjusting the default connection to the SQL Server on the client side, using either Named Pipes or TCP as the default?

Named Pipes Error

Apr 30, 2008

I'm working on an insert into a database and I barrowed this code stright from Microsoft, changing the info I need. I keep getting an 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)" This is the same connection string that I use for querying the database without a problem. Anyone have any ideas?
