I have created a SQL Server Express instance on RDS. I have also created a security group and enabled SQL Server port range 1433 to everyone. I have also selected Yes for Publicly Accessible.
When I try to connect from the Management Studio, I do specify server name as endpoint of the instance including port number. I did specify the master username and master password with authentication type as SQL Server authentication.
I do get this error when connecting:
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) (Microsoft SQL Server, Error: 87)
When I try to see the RDS instance log I see below messages.
2016-12-01 22:31:19.65 Logon Login failed for user 'sa'. Reason: Could not find a login matching the name provided. [CLIENT: 123.249.0.134]
SA is not a possible login, it is disabled in RDS e.g. sysadmin does not exist, nor does the SQL Agent.
Use security groups to control what IP addresses or EC2 instances can connect to your databases on a DB instance. When you first create a DB instance, its firewall prevents any database access except through rules specified by an associated security group.

I am trying to connect Power BI to an Azure SQL Database Server. I am able to connect to the database using SSMS and have added my IP to the firewall settings of the server. However, every time I try to connect Power BI to my SQL Server, 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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)"
I am authenticating to the SQL Server using my Microsoft account, but the error still persists.
I am not sure if you have any network related issues. But, based on my test, everything works fine at my side.
Here are my steps:
1. Set Active Directory Admin for your Azure SQL
And my suggestion here is to add a security group as AD Admin. Then you can add uses to that groups, and all the added users will be administrators.
2. Add firewall rule for your Azure SQL
3. Connect to Azure SQL in Power BI
a). Get Data from Azure -> Azure SQL Database
b). Input your server name and database name
c). Sign in with Azure AD credentials and connect
The account should be set as Active Directory Admin for your Azure SQL Server in step 1.
d). Get data
Recently went through this and was able to connect to a SQL Server with AAD through PBI using the ODBC connection:
Get Data -> Other -> ODBC
Data source name dropdown: (None)
Advanced Options: enter the following connection string:
Driver={ODBC Driver 17 for SQL Server};Server=<SERVER NAME>;Database=<DB NAME>;Authentication=AticeDirectoryPassword
You will then be prompted for your username and password.
I recently install SQL server 2014 in my PC and I selected SQL authentication rather than Windows authentication after completion of installation when I tried to log in my server it shows this error even my server name and password was correct even though it shows this what to do now!!
following is the error message shows when I try to log in.....
TITLE: Connect to Server
Cannot connect to AADI_SQLSERVER.
ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

The network path was not found
As the error states "network-related or instance-specific error" its related not being able to find the instance.
This maybe due wrong instance name, Check the spellings of the server that you are connecting to.
You may have installed a named instance like sqlexpress in that case the server name should be {YourServer}\Sqlexpress.
You can get your instance name by going to services, if its MSSQLSERVER you can connect with the machine name else you should provide the correct instance name.
Please refer the screenshot below.
If you are connecting to another machine check the network configuration of the instance by going to sql server configuration manager. If the status is disabled you can connect from outside.
If that also fails better check the firewall settings
This may be a duplicate question, but i tried all way to connect the SQL Azure database from my local SSMS.
I have created Azure database in cloud and added my system IP in firewall configuration section, As I am on being corporate network and trying to connect azure database from my local ssms then i am getting below 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) (Microsoft SQL Server, Error: 53)"
You need to add your IP in Azure as an allowed IP address.
Go to your database in the Azure portal, select configure -> Add to the allowed ip addresses.
Then connect to < Database name >.database.windows.net
I am trying to connect to a remote sql server. I write the IP a.b.c.d into a server name, then I put username test and password test. This account has all Server Roles selected (I also tried with another account which only had public) and the databases I want to allow the user to manage (in User Mapping section) also have public and db owner. I have completed all the steps in here and I got it working on my local network with another computer in LAN having the server set up.
The error I get looks like this:
===================================
Cannot connect to a.b.c.d.
===================================
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)
===================================
The user name or password is incorrect
But I can connect with the same credentials in the server itself, so I assume either: something is configured in a wrong way or I have to write the login name in some different fashion.
My both MSSQL programs (in two different computers) were installed with SQL Server 2012 Standard and SQL Server 2014 Express and the one I am trying to connect to is SQL Server 2008 R2 Express. However, at work, I have no problem connecting with version of MSSMS being different from the Server, so I doubt it is the case.
Any ideas what I am missing/doing wrong?
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.
