I've added to my .asp website a CreateUserWizard with destination page url home. After I'm launching it in Visual Studio 2013, it opens, I register, but, after a long delay after pressing sign up, it shows me this 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)
Should I create a database myself or how it can't locate the server?
I think that connection string for database is not correct. Try creating an empty database and add that connection string in web config.
The error is telling you it can't find the database you have specified in your connection string (perhaps a typo or an incorrect details)
this page will help you create the connection string. You will just need your server details

I created this project on my another system and completed. I used code first migration for creating database. On that system, this app was running correctly.
But now when I had transferred the project to another system, Its package manager is showing 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

Specified)
I tried with Update-Database -Vebrose, I observed that it is targeting wrong data source, which was in that system where I created the project. How to solve this issue?
Check if the app.config has the connection string set. It may have the connection of the "old" machine that is now unaccessible.
Is the SQL Server configured to allow remote connections?
Is the port 1433 (the SQL Server default port) open?
If you only have the text you sent in the web.config, the connection string might be elsewhere.

I tried making a site for a school project and when I go ahead and input values in the labels in the register page and send it starts loading for some time and then opens up the code in the server side:
SqlConnection conn = ConnectToDb(fileName);
in this line -----> conn.Open();
and this error msg appears:
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)'
You should check your connection string and that you have enough permissions to connect to that database
This is likely because (1) you have the wrong connection string (Example: Wrong server name), or (2) you're loading the connection string from a missing/invalid configuration file. For example, if you're running in debug mode and you your application is trying to load *.debug.config file.
There are other reasons, like you are using NT Authentication and the identity your application is running under does not have SQL Server access.
I am getting following error every time I try to register new user in Reporting Services Form Authentication. I don't know how to get away from it. I am following the steps from here.
Error message is:
An error occurred while attempting to add the account. 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: 25 - Connection string is not valid)
Any solution?
Your connection string is not correct. Test it in another tool other than your program if you have doubt. First thing to check is if the server is actually accessible as the message states The server was not found or was not accessible.
I'm working on a website using ASP.NET, C# and mssql.
When I run the website on our local server it is working fine.
The following error occurs when I run it on a shared server:

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

I don't know how to play with connection string now since I'm very new to this.
It is recommend to keep the connection string in web.config.
To create a valid connection string with SQL Server (either located on network or locally), use following steps:
Steps:
Create a Test.UDL file at your desktop.
Double click the file to see undermentioned Data Link Properties
Select provider i.e SQL Server in your case
Provide connection details i.e. server, username, password etc. in Connection tab.
Test Connection on connection tab and press "OK".
Open UDL file in notepad to see valid connection string.
UPDATE
check following link for creating UDL http://msdn.microsoft.com/en-us/library/e38h511e(v=vs.71).aspx

So Basically i have a POS system with its own database and my website which is hosted on a shared 1and1.com hosting company server which also contains a database with a database design needed.
My aim is to only upload those products that are active- true.
My solution to update the website database from the POS database is to have a special admin page on the website that a connection string of the POS database is entered. The admin.aspx.cs calls a stored procedure that gets all the specific data from the POS database and insert them into the website database.
This all works perfectly when testing on a colleagues machine acting as the website+ db.
But when it comes to loading on the 1and1.com host it returns an error 26.
SqlException was unhandled 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 connection string is the following
Server=IP_ADDRESS_OF_POS\SQLEXPRESS;Database=CentricDatabase;User ID=centric;Password=XXXXXXXXX
Does anyone have an idea why this isn't working on the host? but works on a colleagues machine?
Thanks
