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

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :Sql Server
 

On windows 2008 using sql 2k8 standard edition. I have a couple of apps that run on the server. One works perfectly and attaches to sql with no problem. The second app that uses THE EXACT SAME CONNECTION STRING and gives me the following error,

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

How can one app work and the other not? What can I check for?

Thanks,

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

  

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:

  1. Installed SQL Server 2005 Developer Edition on a machine with WinXP SP2 and enabled remote connections over TCP/IP
  2. Installed SQL Server 2005 Standard Edition on a machine with Win2003 SP1 (remote connections over TCP/IP enabled by default)
  3. 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
  4. A

Named Pipes Provider: Could not open a connection to SQL Server [2]

  
Hi

I'm a complete sql/asp.net newbie and want to try this tutorial:
http://beta.asp.net/GuidedTour/

First I installed:
Visual Web Developer 2005 Express Edition Beta 2

systemsettings\software shows the "sql server 2005 express edition ctp (sqlexpress)" installed

mmc\service shows me the SQL Server (SQLExpress) is running

Following the guided tour I use the commandline, type cmd, and type in the commandbox:
 
"C:\Program Files\Microsoft SQL Server\90\Tools\binn\SQLCMD90" -S "localhost\SqlExpress"

Instead of localhost I also tried computername.smallbusiness.local (thats my fully domain name).

However I always receive the error:

Named Pipes Provider: Could not open a connection to SQL Server [2]

Thank you very much for all your help


Named Pipes provider error - backup script

  
I have a couple of installs of SQL Server 2005 Express.  One thing it doesn't provide is an agent to schedule jobs so I read where you can use Windows job scheduler to execute a batch job to in turn run a sqlcmd file.  I have that working on one server but on the other server I get the dreaded Name Pipes provider error and it goes on to talk about it may not be setup to allow remote connections.  If I check using Surface Configurator it is set to allow remote connections using both tcpip and named pipes.  To my knowledge all I want it tcpip but I enabled named pipes in an effort to get things working. About the only difference I can see is on the working system the database is a named instance (ie. Servername) versus default instance on the non-working system which shows up as (Servername\SQLEXPRESS).  Hopefully I have my terminology right here. Any tips on how to troubleshoot?  Does it depend on the username I am using?  Domain admin or local server admin or what have you? I should mention I can execute the backup script and it does work.  It is when I run the batch job that it fails. The batch job just says "sqlcmd -i d:\MSSQL_Jobs\backup.sql -o d:\Logs\sqlbackup_output.txt"

Server 2008 R2 -> Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error mess

  

So I am using the aspnet_regiis.exe tool to encrypt sections of the web.config in my asp.net applications and services.  I have done this for years successfully on Windows Server 2003 (IIS 6).  However I just moved some apps over to Windows Server 2008 R2 (with IIS 7.5) and I am now receiving the following error at runtime:

"Server was unable to process request. ---> Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: Bad Data."

Now I am quite familiar with this process and am stumped at what I have missed this time around.  I have done ALL of the following which typically suffices for the process on the server. PLEASE READ ALL AND DO NOT PROVIDE RESPONSES OR LINKS FOR THINGS I HAVE ALREADY DONE Thanks!!  Wink

      Hello,Please bear with me as I am no Sql Server guru, but am getting this error that is preventing me from continuing with my development work.  I am the only developer on my team running Sql Server 2005 and it has been working just fine for the last week.  I opened the Management Studio this morning, just like every other morning and got this error:TITLE: Connect to Server------------------------------ Cannot connect to (local). ------------------------------ADDITIONAL INFORMATION: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) Of course the help page says no help is available.  I have googled myself sick and still have not found a way so resolve this...has anyone else had this error and/or a fix?  I am using XP Pro SP2...any help would be greatly appreciated!Thanks!Steph

Framework 2.0 changes - TCP Provider, error: 0 - An existing connection was forcibly closed by the r

  
If you connect to a server and open a query in SQL Managment studio (2005) and looses connection and then regain the connection, when you try to run the query it gives me a "TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host."
 
This happens against both 2005 and 2000 servers.
 
If I re-run the query it works.
 
However, this happens in our VB.NET app as well for clients with Wireless connections.
 
So, something has changed in Framework 2.0 regarding this, does anyone know how to tell the client to not throw this error and just try connecting the server instead which will work?
 

Damn this (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

  

 

Well my problem is this error message Message="A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"

 

but :

 

-can't connect to SqlServer Express 2005 on my network server from my application while ITS RUNNING. What I mean is that when I use Server Explorer Window on VS2008 every thing is fine (I can even insert and modify data from server explorer), in fact, when I use Datatables and I choose to preview data through TableAdapters (Design Time) I get data, and also can run the queries from there directly to the data base, but when I'm debbugin the application I get this error.

 

-when I run Sql Server Management Studio, its also fine, even though I can't see the Sql instance on the server (or any of my partners machine) when I try to browse them. But if I type the server path (servername\instancename) everything is OK.

 

-I know the problem is not the connection string 'cause mya partners nd I use the sa

Test Connection Failed because of an error initializing provider

  
I have a question as to why I cannot connect to my SQL Server.  I am no SQL man so please bare with me.  I was initially creating a sharepoint site and trying to configure a database but the Configuration Wizard would fail stating it could not find a user.  I was then informed I could created a .UDL file to attempt to test my connection.  That is where I am at.  I can see the SQL server, and when I use Windows NT Integrated security, my connection is successful.  When I use a specific user name or password, I cannot connect to it.  The only connection that is successful is the sa user.  Can anyone point me in the right direction as to where I should check my permission levels? 

I checked on my server roles and security roles on SQL and the account that is being used to create the sharepoint site is a securityadmin, dbcreator, public and sysadmin.  

Surface Area configuration is allowed to have remote connections for TCP and Named Pipes.  I even ensured that DTC is allowed to have remote connections on both machines.  

Any help would be greatly appreciated.  Thanks!
