An Existing Connection Was Forcibly Closed By The Remote Host?

May 19, 2010

I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while or pass a large amt of data to a web service in a dataset, I get the subject error.The error seems to occur in < 1 min, which is far less than the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server.It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server:System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the rem

Existing Connection Was Forcibly Closed By Remote Host

Sep 19, 2011

I have an application that copies a file from a network/internet location. I am trying to catch the exception for when the network connection becomes unavailable (or internet goes down). Currently i catch the exception "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host." which occurs on the bold, underline line below.The issue i have is i try and attempt the operation to continue doing what it was doing by resetting variables and then reassigning them to continue reading the stream but cant get past this error. The only way to go past it is to stop and start the application which is not what im after. [code]

Error: 0 - An Existing Connection Was Forcibly Closed By The Remote Host

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 with MSSQL 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.

Remote Desktop - Modify That Program To Allow Me To Connect To Computers Not On My Network?

Jun 12, 2011

I have created a program that allows me to remotely access computers on my network (not all done by me i found some code online) however i want to modify that program to allow me to connect to computers not on my network. How can i go about doing this? My program consists of a client and a server. When the server runs it listens for the client on the client side i enter the IP address and it connects so i can send remote commands to the remote system.

TCP / IP Server - Remote Connection Fails To Connect

Mar 27, 2009

I've came across a little problem with my tcp / ip server. My client can connect to it with ( localhost ), and 192.168.0.X, but every remote connection fails to connect.

Here's the connection rituals:
listener = New System.Net.Sockets.TcpListener(System.Net.IPAddress.Any, Port)
listenThread = New System.Threading.Thread(AddressOf doListen)
listenThread.IsBackground = True

client = New System.Net.Sockets.TcpClient(IP, Port)
client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf DoRead, Nothing)

.net - How To Handle TCPListener "An Existing Connection Was Forcibly Closed By The Remote Host"

Aug 5, 2011

I have a tcp server that uses TCPListener and the async method BeginAcceptTCPClient:

Imports System.Net.Sockets
Imports System.Threading
Imports System.Net
Public Class TCPServer


My problem is that infrequently, I get an exception in the HandleAsyncConnection method:"An existing connection was forcibly closed by the remote host" right at the EndAcceptTCPClient method. At this point, the TCPListener seems to stop listening. The problem is that I can't test this easily, as it only happens on a remote test VM and only once every 24 hours or so. If I knew how to recreate the error with a test client, I would be able to figure this out. Wireshark shows a reset [RST] packet being sent at around the time of the exception. So I either need to know how to handle the exception, or how to recreate the problem with a test client.

Connect To Remote Computer And Display The Status Of Process Running On Remote Computer?

Dec 27, 2009

I'm trying to develop  a windows application where i can get connected to remote server and look for process state going in remote server.We have many remote servers where automatic installation of software going on. We have an xml file(installstatus.xml) where it tells us at what stage the installation is (Example : Inprogress , Completed, Failed.)

So our aim is to develop a windows application where i can get connected to that servers and look for their installation status(may be we can use installstatus.xml to look for installation status). Every time i connect to a server, the server information should get stored in XML file(i want to create a xml file where all the servers list i connect to should get stored)

The UI at left side should will have list of servers i can connect to. When i get connected to server, at right side of UI, i want to display the status of installation (In progress, failed , completed).

Communicating With Remote Host & Port?

Oct 1, 2009

I've been trying for a long time to do what seems to be the most simplest of things..I have a remote host and I need to know if certain posts on that host are open or closed.Many examples on the net that I have found arent complete, and because I havent worked with for long I dont knowhow to complete them.Here is my code:: The issue is with this it tell me the target port is always closed, when I know that it is open.Code:Dim host As String = "" Dim port As Integer = 80 Dim addr As IPAddress =CType(Dns.GetHostAddresses(host)(0), IPAddress) Try Dim tcpList As New TcpListener(addr, port)tcpList.Start() Catch sx As SocketException MessageBox.Show("port is closed") End TryA friend of mine suggested using WinSock.. I've not dealt with it before so I don't know what he's on about.

VS 2010 - Get Installed Software From Remote Host. Win Vista/7?

Nov 19, 2009

I have created a Windows service that runs on one of our servers. The service lisens to incoming connections on a set socket port, runs a series of WMI queries on the requested computer in a new thread (the socket accepts a string value as input which is the hostname to scan), creates an xml file based on the collected data, and posts it back to a webserver. This works perfectly on all WMI queries, but i have one function that gets all installed software from the requested host using the RegistryKey.OpenRemoteBaseKey method to get all keys from the "SOFTWAREMicrosoftWindowsCurrentVersionUninstall" key on the target host. If the the target machine OS is Window Vista or 7, it returns no values. If i run this code on the target machine it works, but not from the service on a server. The service is installed and runs with full domain administrator rights. I guess this is a permission issue, but i have not found a good solution on how to solve it on the internet. As a workaround i use WMI to get a list of installed software from computers running Vista or 7. The problem with the WMI method is that it's very slow. It takes 10 - 15 seconds just to loop thru all ManagementObjects in the Querycollection. Maybe i could filter the WMI query better before starting the loop ?

Open A File From A Remote Network Share?

Jan 14, 2010

I am trying to open a file from a server

I currently have

Dim attachedFilePath As String = "\myservermyshare est.txt"
File.Open(attachedFilePath, FileMode.Open, FileAccess.Read, FileShare.Read)

This does not open a file.

However, if I change the path to be local then there is no issue.

Dim attachedFilePath As String = "c:... est.txt"

C# - Application To Connect To Remote Server

May 11, 2012

Scenario: I want to develop an application.The application should be able to connect to my remote server and download data to the local disk , while downloading it should check for new files and only download the new ones simultaneously creating the required(new) folders. What am i doing?: The app first checks for internet connection , if available pings the server to check if the server is active.Then it has to download the new files.

Problem: I have no idea how to compare the files in the server with the ones in the local disk.How to download only the new files from the server to the local disk? What am thinking?: If i can create the exact folder structure(hierarchy) in the local disk as it is in the server...than i can download the new files accordingly to folders by maintaining some index file in both server and local disk.

Copy The MSI From The Network Location, Store It Locally On The Remote Computer, Then Run It?

Apr 18, 2011

I'm using System.Management.ManagementScope to connect to a remote computer and install an MSI package. This works great if the MSI is located on the remote computer, but it fails if I try to use a network location to run the MSI from. The UNC path is correct because if I manually type it from the remote computer it runs fine. There must be a limitation (security I'm thinking) that prevents things from running via WMI if the exe isn't local to the remote machine.My last hope will be to copy the MSI from the network location, store it locally on the remote computer, then run it - but I'd really rather not have to do that.
