I am trying to connect to SQL Server Management Studio with Azure server, but an error happens:
A network related or instance specific error occurred while establishing a connection to SQL Server
I am using my credentials too.
server name : faena4vikq.database.windows.net
username : "Myusername"
password : "Mypassword"
I have also added my IP address in Azure server configuration panel.
My services are also running.
In Azure database connection string is also showing same :
Server=tcp:faena4vikq.database.windows.net,1433;Database=mjdData;User ID=mjduser#faena4vikq;Password={your_password_here};Trusted_Connection=False;Encrypt=True;Connection Timeout=30;
What do I need to check else?
Is that your real server name? It seems that is does not exist.
Thanks,

I created an Azure SQL Server. I have set the firewall, added my IP address to the rules. I tried to log in using SQL Server Managment Studio but got the network error every time. I am using the Server Admin Login and password created while creating the SQL server. Are there any more steps required to log into the SQL Server?
Note: I also enabled port 1433 for inbound connections on my PC.
According to the error message, we should check the server name of the database.
We can select the database here, and SQL Server Managment Studio will type the server name automatically:
Another way, we can find the information via azure portal, then type the server name manually:
It seems you are using named pipes to connect to SQL database. What happens if you specify TCP/IP protocol in advanced properties tab?
Thanks Everyone for your inputs. The only issue was, the firewall was blocking the port 1433. After opening it, I could connect to the SQL Server hosted in Azure. The link below mentions the requirement to open the said port. https://learn.microsoft.com/en-us/azure/sql-database/sql-database-develop-direct-route-ports-adonet-v12
I'm trying to connect to my local machine name as "Server Name", and giving windows authentication, but its throwing some 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)"
Please note previously it was connecting all well some few months back, but now it throws error. I tried lot of alternatives provided around the web, but nothing worked.
Did I miss something ?
If the service is running on your local machine, try connecting with "LocalHost" as the server name.
Also, did you check that the service is running?
There are several reasons for this to happen:
Check if your SQL is up and running
Check there is no firewall messing around
Check on the configuration manager if sql services is up
Check if TCP/IP is active on the configuration manager
Sometimes, I know is weird, but his error shows up if you haven't configured your server for mixed security (both windows and SQL Server). Try connecting with a windows user with SA permissions and activate SQL authentication as well.
To do this, open SQL Server manager and connect with the SA user, right click on the server properties, check the "Security" tab for "SQL Sever and windows authentication mode"
Check this blog post that will lead you from some of the points I told you.

To clarify this in the start. I don't have much experience with SQL Server so every help will be appreciated.
I have a task to set up some program with a SQL Server Express database which is located on a remote server. The database is, as far as I know, configured and should be working. This is the information I have to connect to the database:
IP: xx.xxx.xxx.xxx
The administrator password is 'somepassword'
The SA password is 'anotherpassword'
I think this info is incomplete because there is no username. But what worries me is that I don't get feedback that my password or username are incorrect. Instead I get the error:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server...
I'm using SQL Server Management Studio to connect to the database (SQL Server 2012 Express) and I added an exception in firewall for Management Studio.
And what is the difference between administrator and SA (system administrator) password?
The message you are receiving basically means "I can't connect to SQL Server". It can be due to a number of issues:
The SQL Server service is not running
The SQL Server instance is not configured to use TCP/IP to communicate
The database is using windows authentication and the user is not authorized or
The database is using mixed-mode authentication and the user/pass is incorrect
As for the usernames you are given, I would assume that the "administrator" username is local windows administrator of the machine SQL server is running on, and that the "sa" user is the default database administrator, that is installed when setting SQL Server to use mixed-mode authentication.
So, I would recommend to try connecting to the database using Mixed-mode authentication, with the username "sa" and the "anotherpassword" password.
I have checked the instance name, auto close is set to true, allow remote connections on the server is checked. The server is running when I open the SQL Server configuration manager. I have even rebooted. I have created this db the same way as all others. I use Entity Framework and have checked the names in the web.config and they match. This is the default connection string from the wizard - I use for testing before I deploy. I just can't think of anything else to check to figure out why it won't connect. Working inside SQL Server everything is fine.
Here is the general 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: Shared >Memory Provider, error: 40 - Could not open a connection to SQL Server)
Config:
connectionString="metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string='data source=.\SQL_1;attachdbfilename="C:\Program Files (x86)\Microsoft SQL Server\MSSQL10_50.SQL_1\MSSQL\DATA\A_db.mdf";integrated security=True;connect timeout=10;user instance=True;multipleactiveresultsets=True;App=EntityFramework'" providerName="System.Data.EntityClient" />
Thanks in advance.
Let me preface this answer by saying that proper setup of a SQL instance is not as easy as Microsoft would like you to think with the entity framework. It's a little bit involved and requires that you put your DBA hat on for a little bit.
The error you have indicates that the web instance is attempting to connect to the SQL server using Windows Integrated Security. This will work fine if (a) the windows user that the process is running as (which can be configured in IIS) is authorized to log on to the SQL server and has a valid login in the database and (b) if the SQL server is on the same machine or in the same domain as the IIS server.
In light of this, I recommend using SQL Server authentication. If you need to know how to do this, I recommend searching for "SQL Server Authentication setup" - here is an article that I found which might help you set this up.
http://msdn.microsoft.com/en-us/library/aa337562.aspx
In general, I recommend taking the following actions:
Connect to the sql server using MS SQL Management Studio.
Permanently attach your database, then use the Initial Catalog property on your connection string rather than AttachDbFileName
Then set up your login username and password on the SQL server, and create a login in the database for it.
Make sure your login can only execute the stored procedures you want it to execute. Deny it access to running sql statements.
You will also need to add the username and password to your connection string, and set IntegratedSecurity=false.
Let us know how things go once you get your SQL server set up properly.
This error means that your provider code cannot find the SQL Server. If you have checked the server instance name (it should be <yourLocalServer>\SQL_1), then it could be the attachdbfilename= parameter, as this is a really unreliable way to specify the database to connect to (you should be using the Database Name, not the file name), because there are about a hundred reasons that the file name could change that have nothing to do with your application.
In Visual Studio 2010 I am trying to set up a connection with a SQL Server database with the add connection wizard but the connection fails!
This is the error I get:
a network-related or instance-specific error occured 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)
Extra info;
I can ping the server!
Remote connections are allowed on the SQL Server!
SQL service is running!
What is here the problem?
To work around this problem, use one of the following methods depending on the symptom that you are experiencing:
A SQL Server login
Use a valid Windows login to connect to SQL Server. If you must continue to use a SQL Server login, you can change the security authentication mode in SQL Server to SQL Server and Windows.
A Windows account with insufficient permissions
To work around this problem, you must add the Windows account to SQL Server, and then grant the appropriate permissions to each database that the user requires access to.
