A Transport-level Error Has Occurred When Receiving Results From The Server. (provider: TCP Provider, Error: 0 - The Handle Is I
Mar 8, 2007
Hi,
Basically the error that I am getting is in our test automation when running as non-admin on the box (regular user). We use .Net C# SQLConnection class to connect to SQL express 2005 impersonating with admin credentials. After getting the connection we try to execute a select command and it some time fails with following error:
A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The handle is invalid.) at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParserStateObject.ReadSniError(TdsParserStateObject stateObj, UInt32 error) at System.Data.SqlClient.TdsParserStateObject.ReadSni(DbAsyncResult asyncResult, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParserStateObject.ReadPacket(Int32 bytesExpected) at System.Data.SqlClient.TdsParserStateObject.ReadBuffer() at System.Data.SqlClient.TdsParserStateObject.ReadByte() at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.ConsumeMetaData() at System.Data.SqlClient.SqlDataReader.get_MetaData() at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader()
This happen only in the non-admin scenario mentioned above. Any idea what is triggering this?
I am trying to run a stored procedure which retreives 3 lakhs of records and updates the data and moves few of those records to some tables. Since the number of records are more , the time taken for the storede procedure is around 30 minutes when i directly execute it in query analyzer.
But I need to execute it from Visula Studio.Net 2005 (c#). Whole of the application contains only one form with a single button.When I click on the button , this stored procure has to be executed. But I am getting an error as shown below. "A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)"
Database used is SqlServer 2000
How to solve this error?. Any ideas are really appreciated.
We've devoted a resource to this today, but I have to believe it's something easy that we're overlooking. The scneario is that we have a production Web application that until last weekend had a SQL 2000 back end. This weekend we installed a new instance of SQL 2005 and everything works (we tested in a sandbox environment, but someone must not have load tested enough) and never saw these exceptions. So, after the upgrade we now receive 100's of thexe SQL excptions per day:A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)Does anyone know what we've overlooked that's causing this issue?Thanks for any help!
i'm going nuts with SQL server notification thing. I have gone throigh this artical which tells how to set user http://www.codeproject.com/KB/database/SqlDependencyPermissions.aspx. This article show how to create new user and setup for sql server notification.But In my case user was alredy existing in database. which is very common senario in most cases. So i did following( check the SQL script below) but then i get this error "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.)" this my sql script use [master]Go -- Ensuring that Service Broker is enabled ALTER DATABASE [DatabaseName] SET ENABLE_BROKERGO -- Switching to our databaseuse [DatabaseName]GO CREATE SCHEMA schemaname AUTHORIZATION usernameGO ALTER USER username WITH DEFAULT_SCHEMA = schemaname GO /* * Creating two new roles.

When I try and query the linked database I get the following error message:
Msg 109, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: Shared Memory Provider, error: 0 - The pipe has been ended.)
I've been searching the web and have gotten a lot of hits on the error message but have yet to uncover anything specifically related to linked servers or anything closely related enough to help me resolve this problem. Any advice would be appreciated. Thanks.
Hi, A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.) I am using a direct connection from my Gridview to perform a huge database search. the stored procedure will take 10- 60 seconds to execute the query.
What the problem i am facing is when the sp takes long time (more than 1 minutes), then when i try any other operation like calling another sp frm another page, i am getting the above specified error.
I am new to SQL 2005. I have one issue and it is as follows:
I write a simple query and run it; it works fine.
Now I break the network connection and run the query; in this case it runs fine.
But when I reconnect the network and run the query, then I get an error as follows:
"A transport-level error has occurred when sending the request to the server. (provider: Named Pipes Provider, error: 0 - An unexpected network error occurred.) "
Every thing is local here. So how the network issue comes here?
I've tried to search on the web for a solution for this error but i didn't find any working solutions for this problem. We have 2 servers. The first one is the server we use to develop our ASP.NET 2 application. On this server we don't have this error. On the other server (use by our client) we have this error sometime and i don't know why. Both servers have the same configuration and both application have the same web.config file.
I've tried to add a try-catch and retry the query when the error occured. This seems to be working but we don't want to have to change all our connections and since we don't have this problem on the other server we want to find the source of the problem.

I just installed SQL Server 2005 on Windows Vista. I am getting an error "An unknown error occurred in the WMI provider. Error Code 8000000A" when connecting to a web server. The reporting services is running. Is there any other installation that is missing. Please help.
I have just installed MS SQL Server 2005 Express edition along with the SSMSE. I am using windows authentication. When I open SSMSE it connects me to a 'local instance' of the server. From there I right click on Database and select to add a new Database and I get the error above. I think I only need to allow local connections to the engine but I have tried allowing remote conections with all varations of named pipes and TCP/IP. I am running on Windows XP SP2 (home).

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.

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.

It tries connecting to SQL Server 2005. There is no SQL Server 2005 in that system. There is only SQL Server 2000.
I have the aspx code in my local system and the database in another machine.
Could Someone please help me out in solving this problem.
I realised this has been done to death, and so much information out there but I am still in a quandry.
I have had to rebuild my computer.
This is what I did
XP machine using SQL Server 2005 Standard Edition using Windows Authentication NZ6(MSSQLSERVER)
straight default install all the way
unfortunately when ready to run reports from my instance(computer) I received the error as in provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
thought I had it all okayed but obviously something not right
so ended up unistalling then - did the following:
Load SQL Server from disc1 and start install failed on alter Counter Registry key error fixed this from KB article (known error that can happen) restarted Went to Windows Update check IIS is installed - tick is on - IIS - admin tools - make sure asp2 is associated - yes ok Then back to install sql server - there is no instance set up yet Disk 2 and setup .exe
All ok on Reporting Services, Analysis etc.
But once again all seems fine but still getting the error:
connection is all fine in Management Studio - eg I can see tables etc connection is all fine in Business Intelligence - eg I can preview my reports I then can deploy up to - NZ6 open NZ6 eports report is there fine - but just errors
some simple little tick that I have not done!!
I seem to have checked and rechecked everything and obviously doing another re-install does not seem a logical step from here. I will continue to check but if someone jump in and advise please would be great.
I am creating a web site using Visual Studio 2008 & trying to connect to database on SQL Server 2000. My test connection is successful but while debugging the page I am getting this error : " provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server "
Solutions recommended for this were start running the SQL browser instance and enable Namespipes in Sqlserver configuration manager.Did both.. but nothing worked.
I made a Web page, and it works perfect on my local machine, everything is OK, until I uloaded page to the server, it reports this error:

Could anyone help me in solving this issue.
I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.

We experience the 40 error when our Asp.net code runs under IIS and uses named pipes to a sql server 2005 named instance.
We've tried all suggestions found on blogs and KB articles such as making sure the named pipes protocol is enabled, making sure the Browser service is started, making sure Allow Remote Connections is enabled, making sure we're not using Asp.Net 2.0 membership providers, and the list goes on and on.
We boiled it down to a simple test scenario. We open a SqlConnection to the sql 2005 box in the code with the intention of binding a datareader to a gridview, but it never gets that far because the connection.Open() fails.
If we run this test application as a virtual directory in IIS and Asp.Net 2.0, the connection.Open() fails.
If we run this test application from Visual Studio .Net using Cassini (PWS), the connection.Open() succeeds and binds to the gridview.
What could be causing the connection to fail under IIS but succeed under Cassini? We've tried setting IIS to run as a domain user and with digest authentication enabled. That made no difference.
