I have installed SQL Server 2012 Express edition on a pc which is on a workgroup running Windows 10. I have also created an user for access to the database through the VS2013 application.
When trying to connect to the server from the client machine, I am getting a message saying login failed and it is from an untrusted domain. The client is also on the same workgroup. However, after the SQL Express was installed on the "server" machine, the name of that pc was changed. I can connect to the database from the server using SSMS using the new computer name (in the instance). I have set remote connection parameters and also configured firewall rules. Yet I am unable to access the server from the client machine.
I also want to ensure that the database is totally secured against access or intrusion. Anyone having access to the server machine can view/edit the database using Windows Authentication. How best to safeguard against it?
Any tips would be appreciated.

try to make a new user in server machin using SSMS and be sure that you are adding the new user to the Login Part of Security in SSMS . For this you need to Login to SSMS as administrator ...

I am on client network and installed Sql Server Express 2014, Blueprism 6 in win 10.
I am not able to create database after configuring in sql server configuraiton manager.
in my personal laptop, i am able to create DB if we setup "SQL server(SQLEXPRESS)"and "SQL Server browser" in Configuration manager as local system and start running. But same setup is not working in Client networks.
Do we have any other setup for client networks.
The error you are getting is quite self-explanatory. When you install SQL server on your machine, you are automatically assigned as the server's sysadmin.
When you installed the server on the client network, you most likely installed it under a different account than the one you are using now. That account has the sysadmin role and can do anything, other accounts will have no access.
To fix this you need to log to that server (using Management Studio) and modify the authentication settings and/or add a new user with greater privileges.
I am installing an app and I am at the point where I am supposed to provide the server details. I installed SQL Server Express and I also installed SQL Server Management Studio.
This is the screenshot:
I did execute this command
select ##servername
but I got this response:
I am running this on my local machine. How can I find the database server address and also the server password?.
PS: I do not remember setting any password when installing SQL Server.
Thanks.
When you executed the command select ##servername, how were you connected to the server? Running that command required knowing the servername and authentication of some kind. I'm guessing you were connected to DESKTOP-KOJLCIF\SQLEXPRESS or .\SQLEXPRESS using windows authentication.
When you installed SQL Express, there was an option for Windows Authentication or SQL Server + Windows (aka Mixed Mode) Authentication. If you chose Windows Authentication (which is the default if I recall), you will not have SQL Server usernames or passwords.
The app you are installing appears to required SQL Auth, so you need to pick Mixed Mode in your setup (which allows both Windows Auth and SQL Auth). You can find this setting in recent versions of SQL Server Management Studio by right-clicking your database server in object explorer, going to Properties, and then looking at the Security page. Older versions of SQL require going to another tool included in the installation folders-- server configuration or some such, the name escapes me. Change the authentication to "SQL Server and Windows Authentication mode". I believe a SQL Server restart is required after doing this.
You can then create SQL logins with username and passwords and appropriate permissions using the GUI in SSMS (expand security folder under your server and look at the logins sub folder) or via CREATE LOGIN t-sql command.
There is a fixed sql login called 'sa' that will always exist if SQL Auth is enabled. You could right click this login, go to properties, and change the password. Be careful giving out your sa credentials to an app, as that can control the entire server.
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 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 some database problems.
I have SQL Server Developer installed on my local machine. When I open SQL Server Management Studio and log in with windows authentication there is no problem. I have created a new database there and added a new user. The new user is owner of the database.
When I disconnect from my windows session and try to log in with the newly created user in SQL Server authentication mode I get the 'cannot connect to (local)'
Please help!
Have you enabled SQL Server authentication? (During installation and/or afterwards)
If not, connect using windows authentication, right-click on the server instance, go to properties and change auth mode...
