Named Pipes Error. ( All MDAC Versions The Same )

Apr 21, 2008

Ok so i have spent almost 2 days searching google and have yet to find
the answer. Currently I'm getting this error.


"Microsoft SQL Native Client error '80004005'


Named Pipes Provider: Could not open a connection to SQL Server [1326]


/anyof/5or6.asp pages various line numbers"


Now a little bit about the setup.


There are 2 head end Web servers ( one of which never has any issues )
in an NLB cluster with DFS file sharing of the web root directories
and 1 back end database. each server has 3 network cards, 1 is a
private connection shared by all 3 servers, 1 is a cluster
communication connection between the 2 cluster nodes ( cross over ),
and the last one is the Public network ( the one that houses the NLB
IP address and each servers public ip address ) all servers are
running Windows Server 2003 R2 x64 sp2 ( with current patches ),
The version of SQL server is SQL Server 9.0.3042


All versions of the MDAC libraries are the same. After logging in
the the problem server will sometimes ( about 50% of the time ) throw
this error at a random spot in the page. There are about 10 - 20
tables filled with data from the database. This error can appear after
any of these tables has loaded ( this is the frustrating part ) and
sometimes it nevergets the error. The other server never has this
issue.
Currently i have tested by going to the servers IP address ( these are
the default sites on each server )
From the server that is failing I have run persistent pings with out
packet loss to the SQL server during failure. I have run memtest and
received no errors. I really don't know what else there is to
check. and as i have stated before. the other head end server
never gets these errors ( and is using the same ASP code as the one
that is failing. )

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?
Jeff
SqlConnection con = new SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=software.mdf;Integrated Security=True;User Instance=True;");SqlCommand cmd = new SqlCommand("INSERT INTO download_table (username, computer_name, computer type, install type, date, email, agree, title) VALUES (@username, @computer_name, @comptype, @installtype, @date, @email, @agree, @title)", con);cmd.Parameters.Add(new SqlParameter("@username", SqlDbType.VarChar, 50));cmd.Parameters["@username"].Value = username;cmd.Parameters.Add(new SqlParameter("@computer_name", SqlDbType.VarChar, 50));cmd.Parameters["@computer_name"].Value = computer_name;cmd.Parameters.Add(new SqlParameter("@comptype", SqlDbType.VarChar, 50));cmd.Parameters["@comptype"].Value = comptype;cmd.Parameters.Add(new SqlParameter("@installtype", SqlDbType.VarChar, 50));cmd.Parameters["@installtype"].Value = installtype;cmd.Parameters.Add(new SqlParameter("@date", SqlDbType.DateTime, 50));cmd.Parameters["@date"].Value = date;cmd.Parameters.Add(new SqlParameter("@email", SqlDbType.VarChar, 50));cmd.Parameters["@email"].Value = email;cmd.Parameters.Add(new SqlParameter("@agree", SqlDbType.VarChar, 50));cmd.Parameters["@agree"].Value = agree;cmd.Parameters.Add(new SqlParameter("@title", SqlDbType.VarChar, 50));cmd.Parameters["@title"].Value = title;cmd.Connection.Open(); <--- This is where I get the above errortry{cmd.ExecuteNonQuery();}catch (SqlException ex){}cmd.Connection.Close();

Named Pipes Error

Dec 4, 2007



HI,

I am getting an error message when I have installed SQL server 2005 and trying to access it through my component. The error message is €œAn error occurred while establishing a connection to the server. When connecting to the SQL Server 2005, this failure may be caused by the fact that under the default settings SQL server does not allow remote connections (Named pipes provider)?€?

I would be obliged if anyone can help me in this regard.

Regards,

SQL Connection - Named Pipes Error

Dec 27, 2006

Hi all,
I've got a little problem.
I'm working on a ASP.NET project. The applications has 4-layers. When I look in the Data Access Layer and test the typed dataset, then the "Preview Data" works fine. I see the right records from SQL Server 2005.
But when I run the app (default.aspx) in debug-mode, then the system gives 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)"
Please help.....

Named Pipes Provider, Error: 40

Jan 2, 2008

Hi All,

I inherited a web server (I'll refer to as WS1) that is running MS 2003 SP2 with Microsoft SQL Web Data Administrator (I have no clue what version of SQL Server this is? Any idea on how to find it is greatly appreciated, but not necessarily what I'm after in this post). There is a default website (website.com) which resides on the C: drive. This was built with asp. On the default.asp page there is a link to an administrative portion (admin.com). This was built with DotNetNuke (.aspx) and resides on the D: drive. All works fine.

I recently was tasked to set up a new web server (I'll refer to as WS2) with MS 2003 SP2 and SQL Server 2005. I imported the database and websites from WS1 that I needed. Both websites are now on the C: drive. Since WS1 is currently live, I can't use website.com and must use the IP address. No problem...the default website website.com opens fine. I also changed how I call the admin.com site. Since I can't open it as href=admin.com and because I already have a default website, I tried creating a virtual directory under the default site to open it. But I'm getting 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)


Looking through the posts on the web, I'm not sure what to do. I originally thought the problem might be with my web.config. But now I'm not sure. I'm not even close to being a network admin or a dba so keep that in mind when you respond. Here's what I've checked:

1) Surface Area Configuration for Services and Connections >> Remote Connections: Local and remote connections is selected with the "Using both TCP/IP and named pipes" option selected.

2) Computer Management >> SQL Server Configuration Manager >> SQL Server 2005 Network Configuration >> Protocols for MYWEBSITE: TCP/IP & Named Pipes are enabled


I can connect to the database via SQL Server Management Studio, so I know the database is up and running.


Also, the original web.config file for the admin.com website looks something like this:

<add key="WebDSN" value="Server=(local);Database=Database1;uid=userid1;pwd=password1;" />
<add key="SiteSqlServer" value="Server=(local);Database=Database2;uid=userid2;pwd=password2;" />


Hope I haven't confused you, but I probably have. Any help is greatly appreciated.

Many Thanks,

Mark

.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?

Named Pipes Provider, Error: 40 - AAAAAAAAAAAAAAARGH!!

Dec 9, 2007

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.

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

Error 1326... Named Pipes Problem?

Mar 20, 2000

Suddenly all of my logins through ODBC DSN are producing the 1326 error. I also cannot reach the server with the Net View tool, but I can Timbuktu
or PC Anywhere to the machine and work on it. This just happened today and seems to be a freak occurence.

Could an administrator have disabled the ability of Named Pipes to make a connection?

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.

SQL 2012 :: Named Pipes Error From PowerShell

Jun 15, 2015

1) I can connect to SQL Server 2012 named instance from SSMS.

I can launch Power shell in any of the supported data contexts, for example from the named instance.

However when I try to run a query in Power Shell, I get the named pipes error.

2)I can also provide a connection string and connect to the SQL Server Instance form Windows PowerShell after launching SQLPS, the same as in the above. I can open the connection and verify its state, but trying to run a query results in the same error.

I also see that named pipes is enabled in the SQL Server Configuration Manager.

Some of this is the result of some ambiguity in the Windows User Account in Windows 8 computer. Some of this is documented in more detail here: [URL] .....

This link is not directly related to the above problem, but arises out of the ambiguity in the Username retrieval: [URL] ....

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?

Error 5 (Access Denied) And Named Pipes Provider Error 40

Sep 21, 2006

Hello there,

I recently started having trouble with my local SQL Server 8.0 database server. When I try to start it with Enterprise Manager I get the following error:

An error 5 - (Access is denied) occured while performing this service operation on the MSSQLServer service.

Nothing showed up in the SQL Server error logs. If I try to connect to it using the SQL Server Management Studio that came with SQL Server 2005 I get the following (slightly more informative) message:

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

I'm not sure which log to look at in the MSSQL folders: MSSQL.1, MSSQL.2 or MSSQL.3.

Furthermore, if I manually start the MSSQLSERVER service, then I can connect just fine with the SQL Server 2005 Management Studio but still get the weird error message with SQL Server 8.0 Enterprise Manager.

Any ideas?

Thanks

Named Pipes Error (it's Different This Time, I Swear):resolved

Apr 25, 2008

EDIT : It really works well when you try to execute a MSSQL stored procedure against an MSSQL database rather then an oracle one. I was using the wrong connection string. Idiot
 
 
 
So I am getting this familiar 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)
 
However the wierd part about it is that I can use SqlDataSources via my aspx code and all works fine. I am trying to build on into a cs plass and that is when I get that error. I have verified that I can connect and use the database. the login functionality works perfectly fine. I can update, delete, select and insert records all over the place. However the code below produces the above error.
 
 string connection = ConfigurationManager.ConnectionStrings["ersConnectionString"].ConnectionString;

// Change this over to a SQLDataSource and see if that makes a difference
// Still doesn't work need to look into it further

SqlDataSource source1 = new SqlDataSource();


source1.InsertParameters.Add("UserId", UserId.ToString());
source1.InsertParameters.Add("Action", action);
source1.InsertParameters.Add("CurrentTimeUtc", DateTime.UtcNow.ToString());
source1.InsertCommand = "sproc_UpdateUsersCurrentActivity";
source1.InsertCommandType = SqlDataSourceCommandType.StoredProcedure;
source1.ConnectionString = connection;
source1.Insert();
 
all the variables are declared and filled that is not the issue, anyone have any idea?

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.

Named Pipes Error With Remote Connection Problem For Maintenance Plan

Jan 2, 2007

OS: Win 2003 Service Pack I on 2 boxes
SQL: SQL Server 2005 Clustered System

Situation: I have created a maintenance plan to backup my transaction log every hour. This runs fine for some time and then later that day it stops working. This could happen at any anytime, and I end up having to manually kick it off again. I read the SQL error logs and this is what it points to:

[298] SQLServer Error: 2, Named Pipes Provider: Could not open a connection to SQL Server [2]. [SQLSTATE 08001]
[165] ODBC Error: 0, Login timeout expired [SQLSTATE HYT00]
[298] SQLServer Error: 2, 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. [SQLSTATE 08001]
[382] Logon to server 'JAXNVSQL1CLS' failed (ConnAttemptCachableOp)
[177] Job MaintenancePlan Insight Transaction Logs has been requested to run by Schedule 10 (Insight Transaction Log Backup)
[165] ODBC Error: 0, Login timeout expired [SQLSTATE HYT00]

I have already used SAC to confirm that remote connections is enabled using TCP/IP and Named Pipes. I have used the server configuration tool as well to check this. I have used the Studio Management and checked on the remote connections as well.
I know these protocols are enabled and working because I have used the Studio Management to check on the activity connections type and seen both are working. Plus the fact this maintenance plan does work, it just so happens something causes it later to fail. When this does fail, I log onto the server but can not login using the Studio Management , I get [298] errors. I can login using the Studio Management on my laptop remotely but can not manually kick off the maintenance plan. I end up having to log on to the server and restart the MSSQL Server service and manually kick off my plans. (By the way these services do not show shutting down in the Windows event viewer). After restarting the MSSQL Server service and manually executing the maintenance plan everything is fine until the next time it hits a glitch.
I do have SQL Browser up and running, all of the MSSQL services running, I need some help as to what may be causing this problem!!!!!!!!! HELP!!!!! I am losing my mind!!!!

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)?

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

Apr 26, 2007



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'.

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 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.



Please help me in resolving this issue.
