EM Error 'connection Forcibly Closed By The Remote Host' (ouch)

Jul 22, 2005

I am getting this error in Enterprise Manager:
TCP Provider: An existing connection was forcibly closed by the remote host.

But, my web app can still connect just fine to the db, so it's still in
the same place with the same login/password.  And my registration
in EM was working just fine (for years) until yesterday I got this
error.  I've tried deleting the registration and re-creating it
but the same thing.  What could have gone wrong to cause this to
happen? 

Thanks for any pointers, I have no idea where to start looking on this one, the host says they haven't changed anything...

Framework 2.0 Changes - TCP Provider, Error: 0 - An Existing Connection Was Forcibly Closed By The Remote Host.

Nov 14, 2005

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?

An Error Occurred While Receiving Data: '10054(An Existing Connection Was Forcibly Closed By The Remote Host.)'.

Jan 3, 2006

What does this error mean? I get this in the transmission_status column of  sys.transmission_queue

An error occurred while receiving data: '10053(An established connection was aborted by the software in your host machine.)'.

Also, does the number in this message correspond to error 10053 in sys.messages?

Thanks

An Existing Connection Was Forcibly Closed By Remote Host

Jun 26, 2007

Hi all
I have run a stranger issue:
I use ADO.NET 2.0 to access sql2000 database. during the whole process, I need stop sql server service which the program is connecting. my setup is like following:
1.Open a conection to access table and then close the connection;
2.restart sql server service ;
3.Re-open a connection to access table and then an exception was thrown out:
 A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed bythe remote host.)
4. try re-open a connection to access table and then no exception was thrown out.
I think this maybe related with connection pool. any guy know the detail, please give me a response. Thank you very much!

An Existing Connection Was Forcibly Closed By The Remote Host

Feb 13, 2006

Hi,
I'm running a website using MSSQL 2000. Sometimes (not always) I get this error message on the website:
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 have also websites running with MySQL and those don't have this problem.I searched google but I couldn't find usefull information on this problem.
Someone who knows what's going on here ?

The Underlying Connection Was Closed: The Remote Name Could Not Be Resolved

Jan 21, 2008

Our system administrators have renamed the server that our Reporting Service 2000 runs on. The database that RS2000 uses is on the same server.

Now when I navigate to the Report Manager, the following error appears:

The underlying connection was closed: The remote name could not be resolved


Obviously I need to tell Reporting Services 2000 the name of the new server (even though it's just the same server??). Where do I do that?

The Underlying Connection Was Closed: Could Not Establish Trust Relationship With Remote Server.

Sep 21, 2007


I am trying to setup SQL Server 2000 Reporting services with an SSL connection. The SQL Server (Windows Server 2003 SP2 Standard) and Reporting Server (Windows Server 2003 R2 SP2 Standard) are on separate machines. I have tried setting up Certificates from both and Stand-Alone and Enterprise CA. I have tried several combinations of the Issue To name (server | server.company | server.company.local) I have modified the rsWebApplication.config and rsReportServer.config to match the certificate€™s Issue to exactly. I have tried installs with both Domain Accounts and NT AUTHORITYSYSTEM logins. I have managed to get https://server/ReportServer to work but I have had no luck with the report manager https://server/reports. How do I fix this error?


Thankyou

Large Reports - Error: The Underlying Connection Was Closed: An Unexpected Error Occurred On A Receive.

Mar 13, 2008

First off I understand that it is a horrible idea to run extremely large/long running reports, but sometimes it ends up being the best possible solution due to external forces.




I've got a 25,000 page report that we recently converted from crystal reports to SSRS. The SSRS server is a 64bit 2003 server with 32 gigs of ram running SSRS 2005. When running the report through the report manager web application, it renders in the browser/viewer after about 12 minutes. Exporting to pdf through the browser/viewer in the report manager takes an additional 55 minutes. It does work and it produces a whopping 1.03gb pdf.




Unfortunately, I've run into a problem when trying to do this from a console application using the SSRS client API. After about 30-35 minutes I get an exception on the client with the following error:
Exception Message: The underlying connection was closed: An unexpected error occurred on a receive.
InnerException = Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

Here is the api call:




Code Snippet

byte[] m_data = reportingService.Render(this.ReportPath, this.ExportFormat, null,
deviceInfo, selectedParameters, null, null, out encoding, out m_mimeType,

out usedParameters, out warnings, out streamIds);
Here are some things I've tried so far:


set the HttpRuntime ExecutionTimeout value to 3 hours on the report server
disabled http keep alives on the report server
increased the script timeout on the report server
set the report to never time out on the server
set the report timeout to several hours on the client call
Disabled antivirus on the client side, and verified there was no antivirus running on the reporting server.
Tried using default credentials in the ReportingService object as opposed to supplying credentailsAny ideas would be appreciated. I understand the best solution is to split the report up into smaller reports, which is the backup option, but being able to keep it as one report is the goal.

Sql Server Reporting Services Error The Underlying Connection Was Closed

Sep 18, 2007



Hi,


We have a mature instance of SQL Server 2000 reporting services that has stopped working for no apparent reason. When browsing to http://reportserver/reports we receive the following error



Error



The underlying connection was closed: Unable to connect to the remote server.



Home

The installation is running on three servers - 1 sql cluster (sql 2000 sp4) and two IIS servers all running windows 2000 sp4.

The Reportserver website runs using identity impersonation using the .net machine.config file pointing to an encrypted registry key entry holding the userid and password. It has been moved from the default website to it's own website but has been working with no issues for years. No obvious patches have been applied or security changes made that could effect the application


When browsing to http://reportserver/reportserver we can view the loaded reports and even run them with no issues, only ther report manager isn't working.

I have tried changing the impersonation registry key ( using aspnet_setreg ) and the account the reportserver web service runs under ( using the rsconfig utiltity) to be a domain admin to no effect and I have checked and set specififc permission for the reportserver database on all registry keys to no effect.

None of the online solutions for this issue have worked for me. Any help or ideas would be greatly appreciated


Cheers

Can No Longer Access Report Manager - The Underlying Connection Was Closed: An Unexpected Error Occurred On A Receive.

Apr 11, 2008



Hi,

For a long time I've had SQL Server 2000 with RS on a Server2003 machine.
When I want to publish a report from my Dev box, I remove anon. access on the Production machine, deploy the report, then go into report manager to tweak a couple of parameters. I then re-enable anon. access so users can continue.


Yesterday, I removed anon. access and deployed the report but when I went into Report Manager I received the above error message... "The underlying connection was closed: An unexpected error occurred on a receive."


I can get into report manager with anonymous access enabled, but I don't have authority to do anything.


What's happened!!!? More importantly, how do I fix it?

ExecuteReader Requires An Open And Available Connection. The Connection's Current State Is Closed.

Apr 26, 2007

I am accessing SQL2005 with C# code using OleDbConnection.



A try and catch block catches the following error once a while between the Open() and Close() of the connection:

ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.



I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.



Any hint would be greatly appreciated.

Maintaining SQL Data On A Remote Host.

Oct 29, 2007

Hi,What is the preferred way to maintain SQL tables on a remote host?I am a newbie to building ASP.NET websites on a remote host.A stumbling point has been the maintenance of SQL tables on the remote host.I understand about doing complete backup and restores,but I am seeking a quicker way to maintain individual files.I would like to click and edit but instead am going through the following 30+ clicks.Is there a easier way?Thanks.
For example, what I do now to build a new data table for a hosted website.1) Design table 1a) Name 1b) Fields & Types
2) SQL Server Management Studio Express (assuming existing database) 2a) Select Database & Tables 2b) Add new table 2c) Add fields,  Key must be INT for ACCESS 2d) Save as (Name_Table)
3) MS Access  (requires ODBC to be setup first through the Windows control panel) 3a) Tables / New / Link / ODBC /Machine_Data_Source 3b) Pick table 3c) Edit data, as needed
4) To transfer data, first:Select the database in the VWD solution explorer, then right-click and select the new "Publish to Provider" 4a) Database Publishing Wizard   4b) Choose table to script a backup from 4c) Build script & Copy
5) Start Ipswitch FTP ( this step can be rplaced by 6e below) 5a) locate folder & sql script file and choose destination directory 5b) Transfer file
6) Login to remote host host (1and1) 6a) MS SQL Administration  6b) Admin (MyLittleTools Admin) 6c) Tools 6d) Quey Analyser 6e) Paste script (from step 4) 6f) Submit (Run) 6g) Verify table built
FYI: Script to build and populate the new table "Name_Table"Built by step 4c above, pasted into remote Hosts Query Analyzer by step 6e above.
/****** Object:  Table [dbo].[Name_Table]    Script Date: 10/28/2007 18:03:58 ******/IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Name_Table]') AND type in (N'U'))DROP TABLE [dbo].[Name_Table]GO/****** Object:  Table [dbo].[Name_Table]    Script Date: 10/28/2007 18:03:58 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOIF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Name_Table]') AND type in (N'U'))BEGINCREATE TABLE [dbo].[Name_Table]( [ID] [int] NOT NULL, [Name] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Address] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [City] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [State] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Zip] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Acsz] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Phone] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Fax] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, CONSTRAINT [PK_Name_Table_1] PRIMARY KEY CLUSTERED ( [ID] ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  =

Remote Connection Error

Jun 2, 2007

Hi.Its really become a nightmare solving remote SQL Server connection. I thought it was going to be easy. Anyway im using win xp sp2 and sql 2k5 express as testing environment. I followed trouble shooting

tips:

http://blogs.msdn.com/sql_protocols/archive/2006/09/30/SQL-Server-2005-Remote-Connectivity-Issue-TroubleShooting.aspx

and secured all requirements to met one by one.
I created a test script (ASP) running on the same box where the SQL Server was installed and its running perfectly (eg http://127.0.0.1/sql.asp OR http://localip/sql.asp) either using one of the following connection string

cn.Open "Driver={SQL Server};" & _
"Server=live-static -ip;" & _
"Address=local-ip,1433;" & _
"Network=DBMSSOCN;" & _
"Database=xxx;" & _
"Uid=xx;" & _
"Pwd=xxx;"


OR

cn.Open "Provider=sqloledb;Network Library=DBMSSOCN;" & _
"Data Source=local-ip,1433;" & _
"Initial Catalog=testdb;" & _
"User ID=xx;Password=xx;"


now i upload the page to our domain host and try to access but its sending an error:

################ ERROR MESSAGE

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SQL Server does not exist or access denied.

/sql.asp, line 6

########################################

sql browser is also running, and remote connections allowed, port exemption and firewall is turn off but im receiving the same error.

The Connection Gets Closed Right After It Opens.

Jan 27, 2007

I have the Function, that fires from onLoad even of one of the asp:Label controls on my main page.
Here is it's code:
 SqlConnection conn = new SqlConnection();                conn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["UkraineConnectionString"].ToString();                SqlCommand comm = new SqlCommand("SELECT [Greeting] FROM [Misc]", conn);
        try        {            conn.Open();        }        catch        {            Response.Write("Error opening connection in Page_Load of default.aspx to retrieve the greetings");        }
        string MyGreet = (string)comm.ExecuteScalar();
        Greetings.Text = MyGreet;
        try        {            conn.Close();        }        catch        {            Response.Write("Error closing connection in Page_Load of default.aspx after retrieving the greetings");        }        }
When it gests to conn.Open() in the debugging mode I see that the ServerVersion = 'conn.ServerVersion' threw an exception of type 'System.InvalidOperationException'.
The most interesting thing is that it used to work before.
Here is the connection string it retrieves fine.
"Data Source=MDM1;AttachDbFilename=|DataDirectory|Ukraine.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"
 As I said it used to work, but one day I tried to access the web site and it said this error that I get, that the connection is closed. Then I was using the SQL Server Express. When in the Visual studio if I would run this same site in debug, everything was working fine. I decided to uninstall the SQL Express and installed the SQL Server.
If I open the SQL Server Managment Studio in the Server name field I see MDM1(this is the name of the PC, but probably it is the same name for the Server. Well, in the MAnagment Studio it conects fine to the MDM1 so it is no probably the naming problem. Ithink it has something to do with permisssions.
If someon can - please help. Thanks.

Visual Web Developer On Remote Host SQL Problem -- Newbie Question

Nov 8, 2005

Hi,
I just downloaded Visual Web Developer Beta 2.0 and the club starter kit.  I created a new web project using the kit and it worked fine.  I can run the site locally without problems.  Howevere, when I ftp my files over to my web hosting site and try to run the site there I get the error message shown below.  Is there a configuration file that I missed updating or is this an issue on the web hosting site?
 Thanks for your help. Server Error in '/' Application. --------------------------------------------------------------------------------

Question On A Remote Connection Error

Dec 4, 2007

Through the SMS tool, the following error is being received:

===================================
Cannot connect to MyServerMyInstance.
===================================
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (.Net SqlClient Data Provider)

Note: obviously the server/instance of MyServerMyInstance is fake :).

The setup is the developers receiving this error are connecting to the domain remotely through a VPN connection (so they are on a different, non trusted domain). Also, the IP address our server is on uses an internal range that the remote developers already have in use for something else on their network. So we gave them a bogus IP to use where we then perform a 1-to-1 NAT translation on our end to the correct IP. This all appears to work but the developers still receive this error.

We do have remote connections enabled for both TCP/IP and NetBIOS and everyone at our office can connect just fine. With this in mind, what could be some other issues that can cause this? The only other thing I can think of is somewhere (there are 2 firewalls involved - ours and theirs) is that the UDP packets are not being received by the client.

Remote Network Connection - Error 26

Nov 19, 2007



I am converting over from MSDE to SQL Express. My front end program is unable to connect to the database. To troubleshoot, from the remote computer I tried connecting with the management program and I get the Error 26 unable to connect.

Here is what I have done: I made sure that the SQL Server configuration has been changed to allow network connections (both TCP and named pipes). I have disable windows firewall on both machines. I confirmed that I can connect from the remote machined to the server by network browsing. Both machines are running XP Proff. There is no other security software running on either machine.


More Info. when attempting to log on I am using the server authntication, I use "sa" as the user id plus my password.

Goal. The front end of database program connects to the server remotely using a program called Hamachi over the internet. This works without a problem on MSDE. But for now I am simply try to connect using the managment program which lets you browse for other serves. When I do this it shows the remote computer, but not the name of the computer but not the SQL server which I type in like the following: "INTELsql1"

What I have not Done: I have not changed any permissions or added any users to the server, since this does not seem necessary. As stated the user of remote machine can connect to the server and change files.

Would appreciate any suggestions or tips. Thanks.

Connection Error To Remote SQL Instance, Over VPN

Aug 21, 2006

I am trying to connect to an instance of SQL Express through a vpn, simply using the SQL Management Studio, providing the server ip address x.x.x.xMSSQLSERVER, and using SQL authentication login. I receive the following message:

Cannot connect to <server>, etc., etc.

error 25: - Connection string is not valid

Does anyone understand this? I am trying to connect through the SQL Server Management interface, not with a client program that would utilize a connection string. Is there something which prevents Management Studio from working over a vpn?

To connect, I am using SQL authentication, and have verified the login and password locally on the target pc. The SQL browser service is running on the target pc, and I can telnet to the port which it is monitoring, through the same vpn connection. Remote connections are enabled for TCP/IP in the Surface Area configuration on the target pc.

Any help appreciated.

Remote Connection Failure -- Error 26

Nov 19, 2007



Overview. I am converting over from MSDE to SQL Express. My front end program is unable to connect to the database. To troubleshoot, from the remote computer I tried connecting with the management program and I get the Error 26 unable to connect.

(The connection string worked previously (yesterday) when using MSDE as the server. When I installed SQL Express I named it the same instance as the server name under MSDE. I also use server authtication on both with same user name and password. As stated below I cannot connect using the managment console.)

Here is what I have done: I made sure that the SQL Server configuration has been changed to allow network connections (both TCP and named pipes). I have disable windows firewall on both machines. I confirmed that I can connect from the remote machined to the server by network browsing. Both machines are running XP Proff. There is no other security software running on either machine.

I HAVE READ THE POST FROM MAY 13, 2007 AND TAKEN ALL STEPS SUGGESTED EXCEPT MAKING SURE THE BROWSERS SERVICE IS RUNNING ON SERVER WHICH I WILL DO NOW.
