SQL Server :: 2008 Connect To A Remote Server - Network - Related Or Instance - Specific Error

Aug 4, 2010

I am using Sql Server 2008 to connect to a Remote Server. Everything was working fine for the last couple of months, and i was successfully connecting to the remote server. Today it suddenly stopped connecting to the remote server. note that i did not alter any configuration settings. Did my isp block Sql Server. My ISP is using ISA SERVER? The error details are:

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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider) I am using Microsoft Firewall Client For ISA Server for opening ports. But today nothing is working.

SQL Server :: Network Related Or Instance Specific Error

Nov 6, 2010

I recently did an OS reinstall and tried to use my previously-working projects. I found that there was trouble connecting to the database for my aspnetdb.mdf. I have also tried a new project and adding a database to the project but I get the error 'a network related or instance specific...' error. I have tried reinstalling sql server 2005 express but still no luck. When I fire up sql server management studio i see the server name is the same as my computer name. I remember before the os reinstall that the server name was 'sqlexpress'.Anybody got any ideas as to how I can create databases inside of visual web developer again?

SQL Server :: Receiving An Error - A Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server

Sep 23, 2010

I've created a small website with a simple sqlite database using vwd 2010 .net 4. In dev and test envionments everything works fine, however when i promote to my hosting provider i receive the following error:

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)

I've been configuring the connection strings (autogenerated from entity framework and attached db) but unable to get it working on the hosting provider, I'm assuming it's related to permissions but not entirely sure how to resolve - here's the web.config as it stands:

<add
name="ApplicationServices"
connectionString="data [code].....

For info the environments are set up as follows:

- Dev environment is vwd express 2010 with sqlite mdf attached

- Test environment is windows 7 server, iis 7 with appdomain identity set to network service

Configuration :: Error With Writing To DB On Web Server. A Network-related Or Instance-specific Error

May 25, 2010

I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my asp.net web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB

I get the following error :

Server Error in '/' Application.

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)

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: 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)

The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.

I am pretty new to asp.net but I am sure it has to be something to do with the web.config.

C# - Error / "A Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server

Sep 8, 2010

I am trying to create a simple login page in ASP.NET C# but am getting some error.

I googled about the error, and tried all the solutions but to no avail.What am I doing wrong? The error is:

"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)"

I think it's something to do with my connection string which is as follows:

<add name="cn"
connectionString="server=HCL;DataBase=GS;Integrated Security=True" />

"HCL" is another machine connected to my PC through the LAN and this database, "GS", resides on it. Is the problem with the value I am giving in "Server" attribute of the above code? If not what else may I be doing wrong?

DataSource Controls :: 2147467259/A Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server

May 21, 2010

I am using Asp.Net MVC 2.0 for creating a user and assigning properties to the user at the same time. I am using my Windows account to access database on my local computer. I am using pre-installed MVC code o create a user with unique user name and password. User is created OK. Then I want to add profile properties like First and Last name at the same time.

I am creatingProfileBase object:

ProfileBase profileBase = ProfileBase.Create(profileInformation.UserName);

where profileInformation is a RegisterModel and has user info.

When I am trying to:

profileBase.SetPropertyValue(.....);

I am getting the following error # 2147467259 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: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)"}

Why is my connection string works fine the first time and not working now? And how to configure connection to use TCP-IP?

I have SQL Server Browser running ander Local account and openned port in my Firewall.

When I load the asp.net config tool in vs2010 it loads the page up fine but as soon as I click on security I get the following error:-

Code:

There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.

The following message may diagnose the problem: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

Can't Send Smtp Email From Network Using C# Error / Unable To Connect To The Remote Server

Apr 1, 2010

I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network.

But, problem is when I try this code from my work place, it does not work. Shows error:

"unable to connect to the remote server"

From a different machine in the same network:

"A socket operation was attempted to an unreachable network 209.xxx.xx.52:25"

I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail].

Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received.

note that, the code was tested from development environment, visual studio 2005 and 2008.

try
{
MailMessage mail_message = new MailMessage("xxxxx@y7mail.com", txtToEmail.Text, txtSubject.Text, txtBody.Text);
SmtpClient mail_client = new SmtpClient("SMTP.y7mail.com");
NetworkCredential Authentic = new NetworkCredential("xxxxx@y7mail.com", "xxxxx");

.NET Application - Error When Trying To Connect To A SQL Server 2008 Instance?

Jan 3, 2011

I'm trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can't connect with SQL Server (actually is the same but with several modifications).I'll enumarate some information related to the problem:

S.O: Windows 2003 Server
SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes.
ASP.NET version: 2.0.50727
The connections via TCP/IP are enabled to the SQL Server instance? Yes.
The corresponding user that I have in the connection string, actually exists into the database with the "owner" role? Yes.
ORM Tool used: nHibernate

I get the following error when I try to run the aplication into the browser:

Error while establishing a connection
to the server. When connecting to SQL
Server 2005, this failure may occur
because the default settings SQL
Server does not allow remote
connections. (provider: Shared Memory
Provider, error: 40 - Could not open a
connection to SQL Server)

I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can't. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance.

DataSource Controls :: Sql Server Network Related Error?

Jun 2, 2010

I have the folloing sql server error from my ASP.NET website.

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

This seems to be a network related issue. But on the same machine where IIS is running, I have another C# application running that is not experiencing this problem. This happens after the website has been running for a few weeks. Will this be because the database connections are opened but not closed properly?. I wrote a test web page where i just open connection but not close it and I got Time out error when connection pooling is maxed out. Is this memory issue? Memory that are allocated are not deallocated in timely fashion?..

Everything is working fine for a few weeks and after that I get the above network error.

VS 2008 How To Connect To A Database On A Remote Server

Apr 15, 2010

We have a database on our server, here at the office. We now want to create a asp.net website that will be accessible to the public.

Say the domain of the website is [URL] and it's hosted on a webserver of HeartInternet.

When someone connects to that domain, that webpage must be able to pull data from our server that is located here in our office.

In other words the webpage cannot just load data out of the MySQL database loaded on its server, but it has to connect to our server and get data.
