I been trying to connect my AWS based windows 16 server to a Microsoft SQL Server which uses Windows authentication. All I received from the team was the server URL and the database name, I been trying to connect tableau prep to the SQL but all I am getting is the
"SQL Server Network Interfaces: No credentials are available in the security package" error.
I have also enabled Windows authentication on the server but is it possible for me to manually add my Active directory username and password to the windows 16 windows authentication ? how do I approach this ?
Would appreciate any kind of input on this.

I have a computer with several SQL Server instances installed - 2008, 2012 and 2016. From this computer there is no problem to connect to any of them using Windows Authentication.
Now I try to connect to the SQL Server 2016 instance from another computer. On the server computer I've created the appropriate Windows user and SQL Server login. But when I try to connect to this instance from the different computer, the login fails.
Finally I've managed to connect to SQL Server 2016 database engine using following server name:
TCP:ALEXMWIN81,49602
But when I try to connect to the SQL Server 2016 Analysis Services, the login again fails.
Can anybody give some advice on how to connect? All instances are very important and re-installation is a problem.
Thanks in advance. Alexander Mitchenko
When you say
On the server computer I've created the appropriate Windows user and SQL Server login.
This makes it sound like you are creating a local windows login on the server machine. It should be noted that in order to use Windows authentication both your connecting machine and the server need to be on the same domain.
Creating a SQL login is a separate authentication process called "SQL Server Authentication". When you use this methodology you connect with a username and password only. For this process you would connect by putting the login credentials into a connection string.
Do you have multiple domains? This can cause problems.

Does the SQL instance expose all the required ports to the internal network?

Is the server running a Windows Firewall?
What software are you connecting from?
I face the following isuse on a Microsoft SQL Server 2008 R2 (SP2):
Login failed for user ''. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only.
My SQL server has mixed mode enabled (i verified and switch it on and off several times)
I am able to loging from a peer server which is a replica with the same windows accounts
I am unable to loging from a Windows workstation
The DSN configuration in Windows is succesful though
If mixed mode is enabled why would the server tell me it is not?
What could cause the server to believe it is Win authentication only although the setup is mixed mode?
Wireshark did not help.
I traced back the changes on the server it appears that the main administrator user was renamed. A new sys admin user was created and I had to add this user in both Windows SQL Security groups.
I have installed SQL Server 2005, the SQL Server instance name is SOSO, the machine name is HERO, I tried to connect from another computer using SQL Server Management Studio:
Server name: HERO\SOSO
Authentication: Windows Authentication
But I didn't succeed.
SQL Server is enabled to be connected remotely.
So what is the problem?
Windows Authentication uses the Active directory user from the connecting machine to authenticate with the database. Does it have the right permissions to access the database? Maybe try authenticating with a SQL Server database user first. Maybe you've created a SA user on installation, try connecting with that.
But as the other replies also tell, first check network / firewall connection and please provide us with the error message.
i have an asp.net web app that has this in the web.config file in the project
server=[server],15001;Integrated Security=SSPI;Database=DB_NAME
how do i connect to this database from Sql server mgmt studio since there is not use or password in the connection string. i am connecting from a remote machine
When you connect using "Integrated Security", it uses the current Windows credentials of the process - in the case of connecting to SSMS, it will use your current Windows user. If your Windows user has rights to the SQL Server, then you can connect using Intergrated Security.
If you need to connect to the SQL Server using Integrated Security, but as another user, you'll need to do a "Run As..." on SSMS to load it as the different user.
I'm trying to connect to a remote SQL Server Express machine using Windows authentication.
I´m logged on with a user with username Administrator, but when logging in, I get the error message:
Login failed for user guest ...
Why is not using the Administrator account?
Thanks in advance.
For Windows Authentication to work, the target machine has to be on a domain where your Windows credentials will be recognized. If the server is outside of your organization's control, it will not recognize your credentials and you will have to use a Sql Server user ID and password to log in.
SQL Server Express by default only allows local connections - you can enable it, but you have to explicitly do so.
