I am building a web application so I want to connect the web application on local machine to a company SQL Server. When copying the connection string from the same web application sitting on the server to my local web config I get 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)".
Your help will be appreciated....

I'm not very familiar with ASP.NET. How comes my database is not working in my project? what am I missing exactly?
ASP.NET in Visual Studio
The website works when I run the project but once I interact with the database it shows me this error:
"Something went wrong! Contact your devloper
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 cannot connect to any remote SQL Server instances from my system. I used to connect them from SQL Server Management Studio. Moreover, I can still connect to the same SQL Servers remotely from another systems (my colleagues' system).
I am getting 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
Error Number: 53
Severity: 20
State: 0
I have checked:
Named pipes/TCP is enabled.
Remote connections are allowed.
Windows Firewall is off.
Enabled everything in SQL Server Configuration Manager.
Also, I have tried everything mentioned in this post-
How do I fix the error 'Named Pipes Provider, error 40 - Could not open a connection to' SQL Server'?
But still could not solve my problem. Please suggest any method which allows me to fix this error and connect to the remote servers again.
instead of check whether that server system is working or not, because sometimes if the server system is not working means we are unable to connect to that system
Sometimes following error happening in windows application. The error is like
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)
I am having more than 50 forms in my application and most of the times there is no error. But sometimes, there is an error like this and when I am trying to connect sql its works fine.
I have two instances:
Default
Named[dynamics\FINANCE]
running on SQL Server 2014. However, when I try to connect to named instance say (dynamics\FINANCE) using SQL authentication from local SSMS, I get below error message:
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) (Microsoft SQL Server, Error: -1)
I assigned a static port number 1450 to the named instance [dynamics\FINANCE]. I also setup the firewall rule to allow access to Port 1450.
What am I missing here?
Please, apart from management studio, is there any other tool which can be used to connect to a database on a hosting server online. Because I've tried so many times with management studio with the right credentials but I'm still not able to connect. I've disable all firewalls, made the right configuration but I'm still not able to connect.
when I connect I get 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: TCP Provider, error: 0 - No such host is
known.) (Microsoft SQL Server, Error: 11001)
