A Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server?

Aug 23, 2011

I am working on a project using VS2010 SQL2008 and I saw an ODD behaviour , First let me tell you that the app runs without any problem in my developing pc (Windows Xp sp3 32bit)But when I was trying the application in another pc (Windows 7 32bit)I got this exception: A network-related or instance-specific error occured while establishing a connection to SQL server.The server was not found or was not accessible.Verfiy that the instance name is correct and that SQl server is configured to allow remote connections.

Now what is weird in this exception; Is when the application reaches the DataAdpater.Fill(dataset) line I got this exception but when the app reaches the DataAdpter.Insert(....) It runs without any problem .

And what is more weird is that I noticed that the dataset that is used in the previous insert procedure can later be filled with dataAdapter.Fill(...) procedure which it was giving me an exception before .

I tried these things as a solution:

1)Checked SQlBrowser running..

2)No aliases to Sql server at all to remove...

3)remote area connection--OK

4)TCP and UDP port 1433,1434 exception in firewall

5)Unistalled my only antivirus Norton

6)Added Tcp/IP ports in Sql protocols

7)My connection String is : onnectionString="Data Source=ALISQLEXPRESS;Initial Catalog=PALMSDATABASE;Integrated Security=True"

8)Also tried using Sql Server authentication (user Id and password)

what is the difference between fill and insert? My app. runs smoothly on the original pc ,What should I do?

SQL Server Connection Related Error

May 19, 2012

Below error is thrown in a already opened program which connects to different database

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.)

Program details: code done using vb.net with SQL Server 2008 as back-end

Two instance of same exe where running simultaneously in same PC but error was thrown only by one instance

Program uses both SqlConnection (ADO.NET) and ADODB connection (upgraded from VB6) and the error is thrown by both types of connection If the error is due to network problem with the server then why few programs work fine? I am not able to trace the reason for this behavior of the program

Can I know why this error occurs and why only in few programs of same instance

Establishing Connection Between VB 2008 And Microsoft SQL

Nov 29, 2009

I am developing an application with Visual Basic 2008 Express Edition and using the Microsoft SQL Server 2008. I have tried to connect the application to the server and database but I couldn't.I have found the following connection string:[code...]

I really do not know where to put this connection string and how to get its details such as SERVER_NAME_OR_IP_ADDR. I am also using SAVE and SEARCH buttons to save the input form to the database search using SQL queries. Do I have to use a separate function for this string or put it every time I need to connect to the database?

FtpWebRequest/FtpWebResponse - The Underlying Connection Was Closed: An Unexpected Error Occurred On A Receive

Dec 4, 2008

I'm creating a program (Which will eventually be a service) which loops a section of code which downloads files from a variety of FTP servers.All files are succesfully downloaded on the first iteration, however after this the download fails with the following error..."The underlying connection was closed: An unexpected error occurred on a receive."Curiously, the error does not occur if the loop only downloads the same file from the same Ftp server. It only occurs when 2 or more files are downloaded.I use the following code...

'Set credentials

Application To Run On Server Is Giving An ODBC Related Error?

Aug 19, 2009

I've developed a small HR program that connects to the SQL database which is on the local PC. I've created an ODBC connection to connect to this server and the program works fine. I've used VB 2008 Express edition to develop.

My concern is now I want to install this EXE on a server. ON the server, I've created the same databses and successfully created an ODBC connection on the server as well. Also created one shared folder. I copied all my EXEs and DLLS on to this folder. On the server I was able to execute the program without any problem.

From a remote client, I opened this shared folder and try to execute and it was giving me an ODBC related error, basically it was not able to detect the SQL connection.What I want to achieve is to have one EXE. The program did not throw any other errors.

.net - "An Unexpected Network Error Occurred"

Aug 19, 2010

I have a VB .NET Application which I have written for my company which occasionally throws a message "System.IO.IOException: An unexpected network error occurred.", that I have been unable to figure out the issue.The application is a Backup program which to simplify for this post does the following:

1) Checks for H drive or external drive with label of "BackupDrive", if either of these are found it automatically starts a backup of user data

2) Starts an Async thread that deletes older backups based on how many days the user has specified he/she wants to keep

3) Starts the main thread that backups up user data and updates current file/folder and results into a console window.

If the application encounters an error it will email me the results, below are the results from a members of our sales staff this morning:

Time:
10/28/2010 8:25:31 AM
Version:
1.4.0.2

[code]....

This error message happens about once a week from one of our sales staff, and I haven't been able to isolate why. It always seems like everything deletes and Backups normally. If they unplugged their network cable I would expect the delete or backup to fail, so I don't think thats the issue.

A Transport-level Error Has Occurred When Sending The Request To The Server?

Aug 3, 2011

We have an in-house developed VB.Net Windows Forms application that is losing users' individual connections to the SQL Server 2008 R2 database.The bolded message below is what appears.

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 looked at many numerous articles both from Microsoft and others, but have been unable to pinpoint the issue.Sometimes it occurs when the user has been away from the open application for a long-time; others maybe less than 20 minutes.

Sql Connection Error - Re-establish Connection To The Server

May 14, 2010

This will happen at random, and I can always just catch the error and re-establish connection to the server, but I am confused as to why. When doing lots of inserting into the sql server, I only establish one connection that is public, instead of many little connections. I had my doubts on a public sql connection, but it's been running great, and I've seen no problems until this morning. Again, this random moment I hit an error that stated, sql connection state is broken. Is it bad practice to just accept this error, and when it happens, re-establish the connection?

Asp.net - Server Error Asks For Error Specific Page Instead Of Error Details?

Mar 6, 2012

When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->
<configuration>
<system.web>

[code]....

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->
<configuration>
<system.web>
